[0003] The present invention generally relates to exercise systems, apparatus, and methods and, in particular, to exercise systems, apparatus, and methods that include an unsteady platform having a resistance band system.

[0004] Exercise devices are known that are intended to provide balance and strength training for a person's core muscles, i.e., the muscles of the abdomen and back that are often associated with providing balance, stability, and a straight posture. Such devices often include an unsteady platform member upon which a person is to stand and attempt to keep his or her balance. The platform may tend to rotate, tilt, twist, or move in some combination of these motions so as to create an unsteady platform surface for the user. By regaining his or her balance, a user is able to exercise core muscles in the abdomen and back. Examples of patents disclosing a balancing device for core strengthening include U.S. Pat. No. 4,183,521 and U.S. Pat. No. 7,008,359.

[0005] In addition, exercise devices are known that provide a step device upon which a person may step on and step off in order to perform cardiovascular exercises. Such step devices may be used for various other strength training exercises. These step devices may include the ability to adjust the height of the step or may include a step surface that includes a cushion or some other resilient surface upon which a user will step. Examples of patents disclosing exercise devices providing a step device include U.S. Pat. No. 5,683,331 and U.S. Pat. No. 5,562,575. U.S. Patent Application Publication No. 2006/0040796, which is incorporated herein by reference, also discloses an exercise device providing a step and, moreover, providing a degree of unsteadiness during use.

[0006] Still other known exercise devices provide a platform surface with one or more resistive elements that permit the user to exercise an even wider array of muscle groups. Known resistive elements that may be used in connection with exercise devices include coiled springs and elastic bands. A user may grasp and pull a terminal end of the resistive element in order to strengthen various muscle groups, such as arm muscles, leg muscles, shoulder muscles, or back muscles. Depending on the position of the user's body (i.e., standing, sitting, or lying down) and how the user grasps and pulls the resistive element (i.e., pulling with a hand or foot), the user may target a specific muscle group for strengthening. Examples of patents disclosing exercise devices providing one or more resistive elements include U.S. Pat. No. 3,893,667 and U.S. Pat. No. 6,558,301.

[0007] While these devices perform their intended functions, a need exists for a more versatile exercise device that enables a person to have a complete workout experience with a single device, i.e., a single device that may be used for stretching, core strength training, balance training, cardiovascular exercise, and general strength training.

[0082] In a feature of this aspect of the invention, a user may position both hands on the platform and place one foot on the floor or ground and the other foot in the air. The user may then perform a pushup exercise.

[0083] In each pushup exercise, the user may repeat the exercise several times, or in combination with other exercises, as might be required for a particular workout. Additionally, as can be appreciated, a user may also prefer to have a stable surface for use in connection with any of the pushup exercises set forth above. In this regard, the user may choose to attach the platform to the frame in order to provide such a stable surface. Alternatively, the user may choose to use the frame alone for use in providing a stable surface for pushup exercises and other exercises. For example, a user may perform a pushup exercise using the frame. In particular, in one contemplated pushup exercise, a user may position his or her hands at either end of the frame and position his or her feet on the floor or ground. In accordance with another contemplated pushup exercise, the user may position his or her hands at either end of the frame and position one foot on the floor or ground and the other foot in the air.

[0084] The various exercises set forth above may be performed in connection with a stable surface, as provided by the exercise device or the frame, or with an unstable surface, as provided by the platform. Some exercises, discussed in greater detail below, are contemplated as providing a particular advantage to users when performed in connection with an unstable surface.

[0085] In a feature of this aspect of the invention, a user may perform a single leg forward lunge using the platform as an unstable surface. A user may stand with both feet on the floor or ground adjacent to the platform. The user may then lunge with one foot forward and place the foot on top of the platform. The user may bend his or her knee to about a 90° angle before pushing off to return to a standing position adjacent the platform.

[0086] In a feature of this aspect of the invention, various exercises may be performed that use the platform as an unstable surface. In each exercise, the user stands on the platform and may grasp handles corresponding to one or more of the resistance bands. The user may retain the handles at shoulder height with his or her elbows bent or at the sides of his or her body. In this position, the user may turn the palms of his or her hands to face outward. The user may then bend his or knees to about a 90° angle. As the user returns to a standing position, the user may curl or pull the handles such that each is raised approximately at shoulder height. The user may then repeat the exercise. Additionally, the user may incorporate additional steps to the exercise or replace some of the steps with alternate steps. According to one step, the user may continue to raise the handles such that each handle is extended over the user's head. According to another step, the user may extend the handles outwardly away from his or her body in a lateral direction.

[0199] As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

[0200] Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

[0201] Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

[0202] Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

[0203] Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

[0204] When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

[0205] Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.

[0206] FIGS. 1-7 provide various views of an exercise device 10 in accordance with a preferred embodiment of the present invention. The exercise device 10 includes a platform 12 and a frame 14 with the frame 14 supporting the platform 12 above a surface on which the exercise device 10 is placed for use. The platform 12 includes a first platform member 16 having a generally planar stepping surface defining a stepping deck, and a second platform member 18 having a generally planar stepping surface defining a stepping deck (perhaps best seen in FIG. 2). The first and second platform members 16,18 are removably fastened to one another and are arranged in a generally parallel relationship with one another. Each platform member 16,18 may comprise a panel.

[0207] The first and second platform members 16,18 include curved edges 20 at sides 22 thereof. The curved edges 20 of the platform members 16,18 curve toward one another and abut one another when the platform members 16,18 are fastened together. The platform 12 further includes a plurality of end members 24,26. Each platform member 16,18 has a pair of end members 24,26 at opposite ends 28 thereof. As such, there are a pair of first end members 24 and a pair of second end members 26. The first end members 24 are detachably connected to the first platform member 16 and the second end members 26 are detachably connected to the second platform member 18. In addition, the first end member 24 at one end 28 of the first platform member 16 is detachably connected to the second end member 26 at a corresponding end 28 of the second platform member 18, and the first end member 24 at the opposite end 28 of the first platform member 16 is detachably connected to the second end member 26 at the corresponding end 28 of the second platform member 18. When the first and second platform members 16,18 are fastened together, the end members 24,26 essentially enclose ends 30 of the platform 12, and the curved edges 20 of the platform members 16,18 enclose sides 32 of the platform 12, to create a substantially enclosed platform interior space 34 (perhaps best seen in FIG. 8).

[0208] The platform 12, and hence the platform members 16,18 and the end members 24,26, are connected by a plurality of binding members 36 disposed near the ends 30 of the platform 12. The plurality of binding members 36 transect the first platform member 16, the first end members 24, the platform interior space 34, the second platform member 18, and the second end members 26. A portion of the binding members 36 are linearly disposed near one end 30 of the platform 12 and another portion of the binding members 36 are linearly disposed near the opposite end 30 of the platform 12. It will be understood by the Ordinary Artisan that any type of binding member having the physical characteristics needed to perform the functions of the binding members may be used.

[0209] Both of the first end members 24 include a plurality of slots 38 (perhaps best seen in FIG. 16) therethrough that match up with coinciding slots 38 in both of the second end members 26 when the end members 24,26 are connected. The coinciding slots 38 form openings 40 (perhaps best seen in FIG. 16) in the ends 30 of the platform 12. In the embodiment shown in FIGS. 1-7, there are three slots 38 in each end member 24,26, which results in three openings 40 at each end 30 of the platform 12 when the platform members 16,18 and end members 24,26 are connected. It will be understood that a platform 12 including more or fewer openings 40 than those shown in the exemplary embodiment is within the scope of the present invention.

[0210] The platform 12 may have resilient characteristics similar to conventional step exercise apparatus, whereby the impact experienced by a user in stepping onto the platform may be lessened. The resilient characteristics are enabled by the material from which the platform 12 is made and the configuration of the platform 12. For example, it is contemplated that the platform members 16,18 of the platform 12 may be made from nylon, high density polyethylene, or some other material with similar characteristics. In addition, the hollow nature of the platform interior space 34 combined with stiffeners 42 (perhaps best seen in FIG. 8) disposed inside the platform interior space 34 further enable the resilient characteristics of the platform 12. The stiffeners 42 will be described in greater detail below.

[0211] The frame 14 includes a pair of arcuate rails 44 disposed in fixed parallel relation to one another. Each arcuate rail 44 includes ends 46 and a rounded apex 48 intermediate the ends 46 thereof. Vertical planes of the rails 44 are disposed generally orthogonally to the generally planar surface of the first platform member 16. The frame 14 further includes a pair of connection bars 50 disposed in fixed parallel relation to one another and fixedly connecting the ends 46 of the pair of arcuate rails 44 to one another to form the frame 14. The connection bars 50, the intersection of the connection bars 50 and the arcuate rails 44, and the ends 46 of the arcuate rails 44 are encased in a covering 52. The covering 52 aids in inhibiting slipping of the exercise device 10 when it is in use. The covering 52 also provides an easily graspable surface for a user to grip when the exercise device 10 is in use. It is contemplated that the covering 52 will be made from a non-marking, non-slip, soft, but durable material. Examples of possible materials include, but are not limited to, neoprene, rubber, or a low cost thermoplastic elastomer.

[0212] The exercise device 10 may be used in the configuration shown in FIGS. 1-7, which is a stationary configuration 54 in which the exercise device provides stability during exercise by a user. In this stable configuration 54, the connection bars 50 are supported on a surface on which the device 10 is placed, typically the ground, and the exercise device 10 is immobile when a user is positioned on the platform 12.

[0213] The exercise device 10 may also be used in a configuration that is not stable, i.e., in a the rocking configuration. In the unstable rocking configuration, the exercise device 10 is basically turned upside-down relative to the stationary configuration 54. The rounded apexes 48 of the arcuate rails 44 are supported on the ground such that the exercise device 10 rocks back-and-forth from side to side when a force is applied to the platform 12 that is not directly centered relative to the ends of the device 10.

[0214] The exercise device 10 further includes a resistance band system that is housed within the interior space 34 of the platform 12 and that includes a plurality of resistance bands 58. An end 60 of each of the plurality of resistance bands 58 is disposed exterior to the platform 12 so that the user may easily access the resistance band 58. More particularly, an end 60 of each of the plurality of resistance bands 58 exits the interior 34 of the platform 12 through one of the openings 40 at the ends 30 of the platform 12. Each resistance band 58 exits through a designated opening 40 with only one resistance band 58 exiting through each opening 40; therefore, the number of resistance bands 58 corresponds to the number of openings 40. In the exemplary embodiment shown in FIGS. 1-7, there are six resistance bands 58 and six openings 40 with each resistance band 58 having a particular opening 40 through which to exit the platform interior 34.

[0215] It furthermore is contemplated that the resistance bands 58 at each end of the platform will have varying resistances so that varying amounts of strength or exertion are needed to engage and expand the respective resistance bands 58, and that each end of the platform will have a plurality of resistance bands that are the same as the plurality of resistance bands at the other end of the platform. Such varying resistance at respective ends of the platform may be accomplished by varying the thickness of the resistance bands, with a resistance band having a relatively greater thickness requiring more force to expand than a resistance band having a relatively lesser thickness. In addition, it is contemplated that a user can combine more than one resistance band when using the exercise device to add further versatility to a workout using the exercise device.

[0216] With particular reference to the resistance bands 58, FIG. 8 shows the exercise device 10 with the first platform member 16 and first end members 24 removed so that the platform interior 34 and a resistance band assembly 62 may easily be seen, and FIGS. 9-15 show various views of the resistance band assembly 62 removed from the exercise device 10. The resistance band assembly 62 is primarily housed within the interior 34 of the platform 12. The resistance band assembly 62 includes the plurality of resistance bands 58, a plurality of pulleys 64, and a plurality of rollers 66.

[0217] Each of the resistance bands 58 has an attachment ring 68 at an end 60,70 thereof. The attachment ring 68 at one end 70—the “anchor end”—is used to anchor the resistance bands 58 to one of the plurality of binding members 36 within the interior 34 of the platform 12. The attachment ring 68 at the other end 60 of the resistance bands 58—the “exit end”—is used to enable a user of the exercise device 10 to more easily access the resistance bands 58.

[0218] For example, a user may attach a user interface to the end 60 of a resistance band 58 using the attachment ring 68. Additionally, a user may attach a user interface to multiple ends 60 of a plurality of particular resistance bands 58 at the same end of the platform using the attachment rings 68 of the particular resistance bands 58. In this way, resistance bands can be combined for greater variability in the levels of resistance. Additionally, a user interface may include, for example, a handle for grasping by the hand or a strap for attachment to a foot or ankle. A carabineer or other mechanism may be used to attach the user interface to each of the attachment rings of the resistance bands.

[0219] As indicated previously, in the exemplary embodiment, each end 30 of the platform 12 has three resistance bands 58 exiting therefrom for a total of six resistance bands 58 available in the exercise device 10. The resistance bands 58 are connected to the previously described binding members 36 that are aligned at opposite ends 30 of the platform 12. Further, the anchor end 70 of each resistance band 58 is anchored to a binding member 36 at the same end 30 of the platform 12 from which the exiting end 60 of the resistance band 58 exits.

[0220] More particularly, following a single exemplary resistance band 58, the anchor end 70 of the resistance band 58 is anchored to a binding member 36 at one end 30 of the platform 12. The resistance band 58 then travels longitudinally across the interior 34 of the platform 12 to a second binding member 36 at the opposite end 30 of the platform 12. The resistance band 58 is partially wrapped around the second binding member 36 such that the resistance band 58 makes approximately a 180° turn around the second binding member 36. The second binding member 36 has a pulley mechanism 64 disposed in surrounding relation thereto that freely rotates around the second binding member 36. The pulley mechanism 64 enables the resistance band 58 to readily change direction and turn around the second binding member 36. After turning around the second binding member 36 and its associated pulley mechanism 64, the resistance band 58 travels longitudinally back across the platform 12 in a direction opposite to the direction in which the resistance band 58 initially transects the platform 12. The exiting end 60 of the resistance band 58 then exits the platform interior 34 through its designated opening 40.

[0221] A pair of horizontal rollers 66 are disposed in the opening 40 above and beneath the resistance band 58 to facilitate more smooth movement of the resistance band 58 into and out of the interior 34 of the platform 12. The smooth movement makes exercising with the resistance band 58 more comfortable, i.e., less jerky, and increases the useful life of the resistance band 58 by reducing friction of the resistance band 58 at the opening 40 as the resistance band 58 expands and contracts.

[0222] Each of the six resistance bands 58 follows the configuration described above for an exemplary resistance band 58. As such, the resistance band assembly 62 includes six pulley mechanisms 64 and six pairs of horizontal rollers 66. With regard to the horizontal rollers 66, the rollers 66 above the platform openings 40 share a common shaft 72 about which they rotate, and the rollers 66 below the platform opening share a common shaft 72 about which they rotate.

[0223] Because the platform 12 has three resistance bands 58 exiting (and initiating) from one end 30 and three resistance bands 58 exiting (and initiating) from the opposite end 30, there is some functional overlap for the binding members 36. More particularly, for four of the resistance bands 58, the anchor binding member 36 for a first resistance band 58 also serves as the second binding member 36 or the pulley binding member 36 for a second resistance band 58 that initiates at the opposite end 30 of the platform 12 from the first resistance band 58. The resistance bands 58 are arranged in the resistance band assembly 62 such that the functional overlap of the binding members 36 does not interfere with the functionality of the resistance bands 58. Rather the arrangement of the resistance band assembly 62 enables maximum functionality while maintaining a compact size, which is desirable for the exercise device 10.

[0224] FIGS. 16 and 17 provide exploded views of the platform 12 of the exercise device 10. As shown, the platform 12 includes a pair of stiffeners 42 disposed in the platform interior 34, one disposed adjacent each side 32 of the platform 12. The stiffeners 42 are connected to the platform 12 by a portion of the binding members 36. It is contemplated that the stiffeners 42 may be made of a foam rubber or neoprene material. The stiffeners 42 further enable the platform 12 resiliency, which was previously described above.

[0225] In use, the exercise device 10 can be used in the stable configuration and the unstable configuration. In the stable configuration 54, a user may sit, stand, or lie on the platform member 16 to perform various exercise movements including cardiovascular exercises, strength training exercises, and/or stretching exercises. In so doing, the user may engage the resistance bands 58 on either end 30 of the platform 12 by attaching handles thereto and causing the resistance bands 58 to expand. The user may pull one or more of the resistance bands 58 with one or more of his or her hands if it is desired to exercise some aspect of his or her upper body. In addition, the user may pull one or more of the resistance bands 58 with one or more of his or her legs by using straps that extend around his or her foot or ankle. As indicated previously, the resistance bands 58 may have varying resistances thereby enabling a versatile exercise experience. In addition, more than one resistance band 58 may be connected to a handle or a grasping member to further add to the versatility of the exercise device.

[0226] In the unstable configuration, a user may also sit, stand, or lie on the platform member 18 to perform various exercise movements. It is believed that the unstable configuration aids in strengthening a user's core muscles and in improving a user's balance. The resistance bands 58 may be used in the rocking configuration in the same way in which they would be used in the stationary configuration 54.

[0227] In addition, the exercise device 10 may also be used in either configuration without the user sitting, standing, or lying on the platform member 18. In this respect, the user may engage the connection bars 50 of the exercise device 10 with his hands to perform various exercises with the exercise device 10 without interacting with the platform 12. Preferably, the connection bars 50 include intermediate portions that are configured to be used as handle bars or handle grips. Indeed, such intermediate portions may include contoured surfaces for receiving the fingers and thumb of a hand in a gripping configuration.

[0228] As will be appreciated, the platform 12 and the frame 14 of the exercise device 10 are not intended to be coupled and uncoupled during use in exercising. Moreover, while the exercise device 10 has been disclosed and described as having a platform 12 that is secured to the frame 14, it is contemplated that, within the scope of the present invention, at least a portion of the platform 12 may be integrally formed with the frame 14 during manufacturing whereby such portion of the platform 12 is inseparable from the frame 14 without destroying this portion of the platform 12 and the frame 14.

[0229] FIGS. 18-22 show various views of an exercise device 100 in accordance with a second preferred embodiment of the present invention.

[0230] The exercise device 100 includes a frame 102 having a pair of side rails 104 and a pair of connection bars 108 disposed at ends 106 of the side rails 104. The rails 104 are disposed at a fixed distance from one another, and the connection bars 108 are disposed at a fixed distance from one another. The connection bars 108 are oriented generally orthogonally in relation to planes defined by the pair of side rails 104 and are fixedly attached to the ends 106 of the side rails 104 to form the frame 102.

[0231] The exercise device 100 further includes a platform 110 having an arched base 112 and a stepping deck 114 removably coupled to one another to define an interior space 116 therebetween (perhaps best seen in FIG. 20A).

[0232] The exercise device 100 also includes a resistance band system having a resistance band assembly 118 that is housed within the platform 110 and that includes a plurality of resistance bands 120 (perhaps best seen in FIGS. 35-39). The plurality of resistance bands 120 are arranged within the interior space 116 of the platform 110 and have ends 200,202 that are disposed exterior to the platform 110 for easy access by a user.

[0233] The rails 104 have relatively level central portions and curved end portions. Vertical planes defined by the rails 104 are disposed generally orthogonally to a surface on which the exercise device 100 is placed, typically the ground.

[0234] The connection bars 108, the intersection of the connection bars 108 and the rails 104, and the end portions 106 of the rails 104 are encased in a covering 126. The covering 126 aids in inhibiting slipping of the exercise device 100 when it is in use. The covering 126 also provides an easily graspable surface for a user to grip when the exercise device 100 is in use. It is contemplated that the covering 126 will be made from a non-marking, non-slip, soft, but durable material. Examples of possible materials include, but are not limited to, neoprene, rubber, or a low cost thermoplastic elastomer.

[0235] The frame 102 also includes a pair of support cross bars 124 disposed near the transition between the curved end portions and level central portions of the rails 104. The support cross bars 124 are arranged in a parallel orientation with the connection bars 108 and serve to support the platform 110 when the platform 110 is received by the frame 102. To this end, the platform 110 includes groves within which the support cross bars 124 are received when the platform 110 is supported by the frame 102. In particular, as perhaps best shown in FIG. 22, the platform 110 is positioned between the rails 104 and is supported by the pair of support cross bars 124 disposed near the transition between the curved end portions and level central portions of the rails 104. The platform 110 thereby is supported on, and is separable from, the frame 102.

[0236] The stepping deck 114 has a generally planar stepping surface and includes sides 128, ends 130, an interior surface 132 (perhaps best seen in FIG. 29) and an exterior surface 134 (perhaps best seen in FIG. 19). Portions of the stepping deck 114 near side edges thereof curve toward a surface on which the exercise device 100 is placed and meet side edges of the arched base 112 when the platform 110 is assembled.

[0237] A cushioned pad 136 substantially covers the exterior surface 134 of the stepping deck 114 (as perhaps best seen in FIG. 19). The pad 136 is preferably approximately 3/16 inches thick. Further, it is preferably made from foam rubber, neoprene, or another non-skid, non-slip, cushioned material. The pad 136 aids in traction for a user stepping on the stepping deck 114.

[0238] The stepping deck 114 of the platform 110 itself further may have resilient characteristics similar to conventional step exercise apparatus, whereby the impact experienced by a user in stepping onto the platform may be lessened. The resilient characteristics are enabled by the material from which the stepping deck 114 as well as the structural configuration of the stepping deck 114. It is contemplated that the stepping deck 114 may be made from nylon, high density polyethylene, or some other material with similar characteristics. In addition, the hollow nature of the stepping deck 114 further enables the resilient characteristics.

[0239] The arched base 112 has a generally rectangular perimeter with sides 138 that are longer than ends 140 thereof. An exterior surface 122 of the arched base 112 includes a pair of arched portions 142 disposed adjacent sides 138 of the arched base 112. The exterior surface 122 further includes a recessed central portion 144 between the pair of arched portions 142. Non-skid pads 146 are disposed on the arched portions 142 of the arched base 112. The non-skid pads 146 are preferably made from foam rubber, neoprene, or another non-skid, non-slip material.

[0240] It is contemplated that the stepping deck 114, the arched base 112, or both, may include indicia indicating a trademark or brand of the exercise device 100. In the exemplary embodiment, the indicia is disposed on the exterior surface 122 of the arched base 112. One of ordinary skill in the art will understand that such trademark or brand indicia may be located anywhere on the exercise device 100 and still be within the scope of the present invention.

[0241] When assembled, the exercise device 100 may be used in the configuration shown in FIGS. 18-22, which is the stationary or stable configuration 190. In the stable configuration 190, the connection bars 108 are supported on a surface on which the exercise device 100 is placed, typically the ground, and the exercise device 100 is immobile when a user is positioned on the platform 110. In addition, the exterior surface 122 of the arched base 112 of the platform 110 is seated on and supported by the pair of support bars 124 and does not engage the ground.

[0242] Alternatively, the exercise device 100 may be used in an unstable configuration. To achieve this configuration, the platform 110 is removed from and used without the frame 102. In this respect, the arched base 112 engages the ground and the stepping deck 114 is oriented for receiving a person thereon. The platform 110, due to the arched base 112, is thereby rendered unstable and is prone to rock back and forth when a user exerts a force on the stepping deck 114.

[0243] Another unstable configuration of the exercise device 100 includes use of both the platform 110 and the frame 102. In this respect, the platform 110 is removed from the frame 102 and the frame 102 is turned upside down and is placed onto the stepping deck 114. More particularly, the support cross bars 124 of the frame 102 are inserted into the grooves 125 of the stepping deck 114, which grooves 125 are dimensioned to receive the support cross bars 124 in frictional snap-fit manner therein. The platform 110 remains in the same orientation as in the stable configuration, i.e., only the frame 102 is inverted. In this unstable configuration, the arched portions 142 of the arched base 112 are supported on the ground such that the exercise device 100 rocks from side to side when a user exerts force on the exercise device 110, whether such force is on the stepping deck 114 or on the connection bars 108.

[0244] The stepping deck 114 and the arched base 112 are connected by a pair of end caps 148 disposed at the ends 130,140 of the stepping deck 114 and arched base 112, respectively. The end caps 148 are identical; therefore, only one will be described in detail.

[0245] As shown in FIGS. 23-24, the end cap 148 includes a plurality of curved indentations 150 that align with corresponding curved indentations 152 in the stepping deck 114 when the end caps 148 and stepping deck 114 are connected. The corresponding curved indentations 150,152 form openings 154 (perhaps best seen in FIG. 18) at ends 156 of the platform 110. In the embodiment shown herein, there are three curved indentations 150,152 in the end caps 148 and at each end 130 of the stepping deck 114, respectively, which results in three openings 154 at each end 156 of the platform 110 when the stepping deck 114 and end caps 148 are connected. It will be understood that a platform 110 including more or fewer openings 154 than those shown in the exemplary embodiment are within the scope of the present invention.

[0246] The end cap 148 also includes a plurality of threaded apertures 158 and a plurality of shaft receiving recesses 160 and shaft receiving apertures 162. The threaded apertures 158 are disposed near corners of the end cap 148 near the curved indentations 150 of the end cap 148. The threaded apertures 158 receive binding members 176 (perhaps best seen in FIG. 35) for connecting the end cap 148 to the stepping deck 114. The shaft receiving apertures 162 are disposed near an edge 164 of the end cap 148. The shaft receiving apertures 162 provide an opening for pulley shafts 166 to pass through. The pulley shafts 166 (perhaps best seen in FIG. 35) are seated in shaft receiving knobs 168 (perhaps best seen in FIG. 27) of the stepping deck 114 and shaft recesses 170 (perhaps best seen in FIG. 31) of the arched base 112, which are described in greater detail below. The shaft receiving recesses 160 cooperate with a portion of the shaft receiving knobs 168 of the stepping deck 114 to receive and retain horizontal roller shafts 172 (perhaps best seen in FIG. 35) of the resistance band assembly 118, which will be described in greater detail below.

[0247] Turning to FIGS. 25-29, and with particular reference to the stepping deck 114, the stepping deck interior surface 132 includes a plurality of threaded knobs 174 projecting orthogonally therefrom. In the present embodiment, the plurality of threaded knobs 174 includes four threaded knobs disposed near four corners of the stepping deck interior surface 132. These four threaded knobs 174 receive threaded binding members 176 connecting the stepping deck 114 to the arched base 112. In addition, the plurality of threaded knobs 174 includes four threaded knobs 174 disposed adjacent four corners of the stepping deck 114 interior surface 132. These four threaded knobs 174 receive threaded binding members 176 connecting the stepping deck 114 to the end caps 148. The interior surface 132 also includes a plurality of shaft receiving knobs 168 projecting orthogonally therefrom. A portion of the shaft receiving knobs 168 cooperate with shaft recesses 170 of the arched base 112 to receive and retain pulley shafts 166 of the resistance band assembly 118, which will be described in greater detail below. In addition, a portion of the shaft receiving knobs 168 cooperate with shaft recesses 160 of the end caps 148 to receive and retain horizontal roller shafts 172 of the resistance band assembly 118, described in greater detail below.

[0248] The interior surface 132 further includes a plurality of ridges 178 projecting orthogonally therefrom. The plurality of ridges 178 are aligned lengthwise with the stepping deck 114.

[0249] Turning to FIGS. 30-34 and with particular reference to the arched base 112, the arched base 112 includes an interior surface 180. The interior surface 180 is generally planar and includes a recessed central portion 182 oriented lengthwise across the interior surface 180. A pair of further recessed ribs 184 transect the recessed central portion 182. The dimensions, location, and number of ribs 184 may be varied.

[0250] In addition, a plurality of raised slots 186 disposed orthogonally to the recessed ribs 184 are aligned along the central portion 182. The raised slots 186 mate with the ridges 178 of the stepping deck 114 when the platform 110 is assembled and serve to inhibit any relative rotational movement between the stepping deck 114 and the arched base 112.

[0251] A plurality of connection openings 188 are disposed at ends 140 of the arched base 112. More particularly, four connection openings 188 are disposed near four corners of the arched base 112. The connection openings 188 are aligned with the threaded knobs 174 of the stepping deck 114. The connection openings 188 and threaded knobs 174 receive threaded binding members 176 connecting the arched base 112 with the stepping deck 114 when the platform 110 is assembled.

[0252] The arched base 112 further includes a plurality of shaft recesses 170 disposed at ends 140 thereof. More particularly, four shaft recesses 170 transect the recessed central portion 182 near either end 140 of the arched base 112. As indicated previously, the shaft recesses 170 cooperate with the shaft receiving knobs 168 of the stepping deck 114 to receive and retain pulley shafts 166 of the resistance band assembly 118, which will be described in greater detail below.

[0253] With particular reference to the resistance band system including the resistance band assembly 118, FIG. 35 shows the exercise device 100 with the stepping deck 114 removed for clarity in viewing the resistance band assembly 118. As with the first preferred embodiment, an end 200 of each of the plurality of resistance bands 120 is disposed exterior to the platform 110 so that the user may easily access the resistance band 120. More particularly, an end 200 of each of the plurality of resistance bands 120 exits the interior of the platform 110 through one of the openings 154 at the ends 156 of the platform 110. Each resistance band 120 exits through a designated opening 154 with only one resistance band 120 exiting through each opening 154, therefore, the number of resistance bands 120 corresponds to the number of openings 154. In this exemplary embodiment, there are six resistance bands 120 and six openings 154 with each resistance band 120 having a particular opening 154 through which to exit the platform interior.

[0254] It furthermore is contemplated that the resistance bands 120 at each end of the platform will have varying resistances so that varying amounts of strength or exertion are needed to engage and expand the respective resistance bands 120, and that each end of the platform will have a plurality of resistance bands that are the same as the plurality of resistance bands at the other end of the platform. Such varying resistance at respective ends of the platform may be accomplished by varying the thickness of the resistance bands, with a resistance band having a relatively greater thickness requiring more force to expand than a resistance band having a relatively lesser thickness. In addition, it is contemplated that a user can combine more than one resistance band when using the exercise device to add further versatility to a workout using the exercise device.

[0255] It is further contemplated that indicia indicating the relative strength or resistance levels of the resistance bands 120 may be included on the platform 110. In the exemplary embodiment shown, the indicia include schematic barbells of relatively smaller and larger sizing to indicate the direction of increasing resistance levels of the resistance bands 120.

[0256] FIGS. 36-40 show various views of the resistance band assembly 118 apart from the exercise device 100. The resistance band assembly 118 is primarily housed within the interior 116 of the platform 110. The resistance band assembly 118 includes the plurality of resistance bands 120, a plurality of pulleys 204, and a plurality of rollers 206,208.

[0257] Each of the resistance bands 120 has an attachment ring 210 at an exit end 200 thereof and a hook 212 at an anchor end 202 thereof. The hook 212 is used to anchor the resistance band 120 to one of a plurality of pulley shafts 166 within the interior 116 of the platform 110. The attachment ring 210 is used to enable a user of the exercise device 100 to more easily access the resistance bands 120. For example, a user may attach a handle or strap to the attachment ring 210 of the resistance band 120 using a carabineer or other mechanism. Additionally, a user may attach a handle or strap to multiple resistance bands 120 in order to add further versatility to the functionality of the exercise device 100.

[0258] As indicated previously, each end 156 of the platform 110 has three resistance bands 120 exiting therefrom for a total of six resistance bands 120 available in the exercise device 100. The resistance bands 120 are connected with vertical pulley shafts 166 that are aligned at opposite ends 156 of the platform 110. More particularly, a plurality of vertical pulley shafts 166 transect the interior of the platform 110 at either end 156 thereof. The vertical pulley shafts 166 are seated at ends 156 of the platform 110 in the arched base 112 shaft receiving recesses 170 and the stepping deck 114 shaft receiving knobs 168. The vertical pulley shafts 166 also pass through the shaft receiving apertures 162 of the end caps 148.

[0259] The anchor end 202 of each resistance band 120 is anchored to a pulley shaft 166 at the same end 156 of the platform 110 from which the exiting end 200 of the resistance band 120 exits. More particularly, following a single exemplary resistance band 120, the anchor end 202 of the resistance band 120 is anchored to a pulley shaft 166 at one end 156 of the platform 110. The resistance band 120 then travels longitudinally across the interior 116 of the platform 110 to a second pulley shaft 166 at the opposite end 156 of the platform 110. The resistance band 120 is partially wrapped around the second pulley shaft 166 such that the resistance band 120 makes approximately a 180° turn around the second pulley shaft 166. The second pulley shaft 166 has a pulley mechanism 204 disposed in surrounding relation thereto that freely rotates around the second pulley shaft 166. The pulley mechanism 204 enables the resistance band 120 to readily change direction around the second pulley shaft 166. After extending around the second pulley shaft 166 and its associated pulley mechanism 204, the resistance band 120 travels longitudinally back across the platform 110 in the opposite direction from which it initially transects the platform 110. The exiting end 200 of the resistance band 120 then exits the platform interior 116 through its designated opening 154.

[0260] A pair of vertical rollers 206 are disposed in the opening 154 on either side of the resistance band 120, and a horizontal roller 208 is disposed above the resistance band 120. Each of the vertical rollers 206 is supported by a vertical roller shaft 172 about which it rotates. The roller shaft 172 is seated between the shaft receiving recesses 160 of the end caps 148 and shaft receiving knobs 168 of the stepping deck 114. The horizontal rollers 208 are supported by a single horizontal roller shaft 214 about which they rotate. The roller shaft 214 is supported between the end cap 148 and the stepping deck 114. All of the horizontal rollers 208 at one end 156 of the platform 110 are supported by the same roller shaft 214. The rollers 206,208 facilitate more smooth movement of the resistance band 120 into and out of the interior 116 of the platform 110. The smooth movement makes exercising with the resistance band 120 more comfortable, i.e., less jerky. The rollers 206,208 also are believed to significantly increases the useful life of the resistance band 120 by reducing friction of the resistance band 120 at the opening 154 during expansion and contraction.

[0261] It is further noted that no horizontal roller is disposed below a resistance band 120, as the platform 110 has only one orientation for intended use during exercising; this is in contrast to the platform 12 of the exercise device 10. Moreover, it is contemplated that the exercise device 10 may include vertical rollers located on either side of the resistance bands 120 in the exercise device 10.

[0262] Each of the six resistance bands 120 follows the path described above for an exemplary resistance band 120. As such, the resistance band assembly 118 includes six pulley mechanisms 204, six pairs of vertical rollers 206, and six horizontal rollers 208.

[0263] Because the platform 110 has three resistance bands 120 exiting (and initiating) from one end 156 and three resistance bands 120 exiting (and initiating) from the opposite end 156, there is some functional overlap for the shafts 166. More particularly, for four of the resistance bands 120, the anchor pulley shaft 166 for a first resistance band 120 also serves as the second pulley shaft 166 for a second resistance band 120 that initiates at the opposite end 156 of the platform 110 from the first resistance band 120. The resistance bands 120 are arranged in the resistance band assembly 118 such that the functional overlap of the pulley shafts 166 does not interfere with the functionality of the resistance bands 120. Rather the arrangement of the resistance band assembly 118 enables maximum functionality while maintaining a compact size, which is desirable for the exercise device 100.

[0264] Like the exercise device 10, the exercise device 100 can be used in either a steady or stable configuration 190; or an unsteady or unstable configuration. In the stable configuration 190, a user may sit, stand, or lie on the platform 110 to perform various exercise movements including cardiovascular exercises, strength training exercises, and/or stretching exercises. The user may engage the resistance bands 120 on either end 156 of the platform 110 by grasping handles attached thereto and pulling the resistance bands 120. The user may pull the resistance bands 120 with his or her hands. In addition, the user may pull the resistance bands 120 with his or her legs using straps extending around his or her foot or ankle. As indicated previously, the resistance bands 120 may have varying resistances thereby enabling a versatile exercise experience. In addition, more than one resistance band 120 may be joined together at a handle or strap to further add to the versatility of the exercise device 100.

[0265] In an unstable configuration of the exercise device 100 with the frame 102 inverted, a user also may sit, stand, or lie on the platform 110 to perform various exercise movements, or a user may engage the frame 102 in supporting himself or herself above the platform 110, such as when performing such as rocking pushups. The exercise device 100 is unstable in this configuration and tends to rock from side to side due to the engagement of the arched base 112 with the ground. This rocking motion is believed to aid in strengthening a user's core muscles and in improving a user's balance. The resistance bands 120 may be used in the unstable configuration in the same way in which they would be used in the stable configuration 190.

[0266] In addition, because the frame 102 and the platform 110 are removably coupled, the platform 110 of the exercise device 100 may be used in exercises without the frame 102, and the frame 102 may be used in exercises without the platform 110. That is, the user may engage the frame 102 of the exercise device 100 with his hands to perform various exercises without interacting with the platform 110. Similarly, the user may engage the platform to perform various exercises without interacting with the frame 102.

[0267] FIGS. 40-44 show various views of an exercise device 300 in accordance with a third preferred embodiment of the present invention. The structural design of the exercise device 300 is very similar to that of the exercise device 100, and the exercise device 300 represents the intended commercial embodiment of the present invention. The minor structural differences will be apparent from contrasting of the drawings.

[0268] Irrespective of the exercise device 100, the exercise device 300 includes a frame 302 and a platform 310. The frame 302 includes a pair of side rails 304 and a pair of connection bars 308 disposed at ends 306 of the side rails 304. The rails 304 are disposed a fixed distance from one another, and the connection bars 308 are disposed a fixed distance from one another. The connection bars 308 are oriented generally orthogonally in relation to planes defined by the pair of side rails 304 and are fixedly attached to the ends 306 of the side rails 304 to form the frame 302. The rails 304 have a modified arcuate shape with relatively level central portions and curved end portions. Vertical planes defined by the rails 304 are disposed generally orthogonally to a surface on which the exercise device 300 is placed, typically the ground.

[0269] The connection bars 308, the intersection of the connection bars 308 and the rails 304, and the end portions 306 of the rails 304 are encased in a covering 326. The covering 326 helps to inhibit slipping of the exercise device 300 when it is in use. The covering 326 also provides an easily graspable surface for a user to grip when the exercise device 300 is in use. It is contemplated that the covering 326 will be made from a non-marking, non-slip, soft, but durable material. Examples of possible materials include, but are not limited to, neoprene, rubber, or a low cost thermoplastic elastomer.

[0270] The frame 302 also includes a pair of support cross bars 324 disposed near the transition between the curved end portions and level central portions of the rails 304. The support cross bars 324 are arranged in a parallel orientation with the connection bars 108 and serve to support the platform 310 when the platform 310 is received by the frame 302. To this end, the platform 310 includes groves within which the support cross bars 324 are received in frictional snap-fit manner when the platform 310 is supported by the frame 302. In particular, as perhaps best shown in FIG. 43, the platform 310 is positioned between the rails 304 and is supported by the pair of support cross bars 324 disposed near the transition between the curved end portions and level central portions of the rails 304. The platform 310 thereby is supported on, and is separable from, the frame 302.

[0271] With particular regard to the platform 310, the platform 310 comprises an arched base 312 and a stepping deck 314 that are removably fastened together to define an enclosed interior space 316 therebetween (perhaps best seen in FIG. 53). The exercise device 300 also includes a resistance band system housed within the platform 310 that includes a resistance band assembly 318 (perhaps best seen in FIG. 53) having a plurality of resistance bands 320. The plurality of resistance bands 320 are partially disposed within the interior space 316 of the platform 310 and have ends 400,402 that are disposed exterior to the platform 310 for easy access by a user.

[0272] The platform 310 and, in particular, the stepping deck 314, may have resilient characteristics similar to conventional step exercise apparatus, whereby the impact experienced by a user in stepping onto the stepping deck of the platform may be lessened. The resilient characteristics are enabled by the material from which the platform 310 is made and the configuration of the platform 310. It is contemplated that the stepping deck 314 may be made from nylon, high density polyethylene, or some other material with similar characteristics.

[0273] The stepping deck 314 has a generally planar stepping surface and includes sides 328, ends 330, an interior surface 332 and an exterior surface 334. Portions of the stepping deck 314 near side edges thereof curve toward a surface on which the exercise device 300 is placed and meet side edges of the arched base 312 when the platform 310 is assembled.

[0274] A cushioned pad 336 substantially covers the exterior surface 334 of the stepping deck 314. The pad 336 is preferably approximately 3/16 inches thick. Further, it is preferably made from foam rubber, neoprene, or another non-skid, non-slip, cushioned material. The pad 336 may be permanently attached to the exterior surface 334 or removably secured thereto. The pad 336 aids in traction for a user stepping on the stepping deck 314. In variations, the pad may include a loose granular material or fluid for providing additional instability when the platform 310 is used.

[0275] The arched base 312 has a generally rectangular perimeter with sides 338 that are longer than ends 340 thereof. An exterior surface 322 of the arched base 312 includes a pair of arched portions 342 disposed adjacent sides 338 of the arched base 312. The exterior surface 322 further includes a recessed central portion 344 between the pair of arched portions 342. As shown in FIG. 55, non-skid pads 346 are disposed on the arched portions 342 of the arched base 312. The non-skid pads 346 are preferably made from foam rubber, neoprene, or another non-skid, non-slip material.

[0276] As shown in FIGS. 46-51, the platform 310 is fully detachable from and reattachable to the frame 302. In particular, the platform 310 may be separated from the frame and placed on the ground with the arched portions 342 of the arched base 312 supporting the platform 310. In this regard, the platform 310 is capable of rocking side to side when a user is positioned on the platform 310. Such rocking motion may aid in strengthening a user's core muscles and in improving a user's balance. Additionally, the resistance bands 320 may be used in the same way as they would be used when the platform 310 is supported by the frame 302.

[0277] FIG. 53 is a plan view of the bottom of the stepping deck 314 of the platform 310 of FIG. 46, shown with end caps 348 detached and displaced from the ends thereof and the resistance band assembly 318 situated therein. FIG. 54 is a plan view of the top of the arched base 314 of the platform 310 of FIG. 46. With particular reference to FIG. 54, the arched base 312 includes side surfaces 380 that are generally planar and an intermediate surface 382 having a pair of recesses 384. The dimensions, location, and number of recesses 384 may vary in accordance with the present invention.

[0278] A plurality of connection openings 388 are disposed at ends 340 of the arched base 312. More particularly, four connection openings 388 are disposed near four corners of the arched base 312. The connection openings 388 are aligned with the threaded knobs 374 of the stepping deck 314 (as shown in FIG. 53). The connection openings 388 and threaded knobs 374 receive threaded binding members (not shown) that connect the arched base 312 with the stepping deck 314 when the platform 310 is assembled.

[0279] The arched base 312 further includes a plurality of shaft recesses 370 disposed at ends 340 thereof. More particularly, four shaft recesses 370 transect the recessed central portion 382 near either end 340 of the arched base 312. As indicated previously, the shaft recesses 370 cooperate with shaft receiving knobs (not shown) of the stepping deck 314 to receive and retain pulley shafts 366 of the resistance band assembly 318, as shown in FIG. 53.

[0280] With particular reference to FIG. 53, the resistance band assembly 318 is primarily housed within the interior 316 of the platform 310 between the stepping deck 314 and the arched base 312. As with the embodiments set forth above, an end 400 of each of the plurality of resistance bands 320 is disposed exterior to the platform 310 so that the user may easily access the resistance band 320.

[0281] The end caps 348, which connect to the stepping deck 314 of the platform 310, provide a series of openings 354 at the ends 356 of the platform. In particular, an end 400 of each of the plurality of resistance bands 320 exits the interior of the platform 310 through one of the openings 354 at the ends 356 of the platform 310.

[0282] Each resistance band 320 exits through a designated opening 354 with only one resistance band 320 exiting through each opening 354. In this regard, the number of resistance bands 320 corresponds to the number of openings 354. In this exemplary embodiment, there are six resistance bands 320 and six openings 354 with each resistance band 320 having a particular opening 354 through which to exit the platform interior 316.

[0283] Each of the resistance bands 320 has an attachment ring 410 at an exit end 400 thereof and a hook 412 at an anchor end 402 thereof. The hook 412 is used to anchor the resistance band 320 to one of a plurality of pulley shafts 366 within the interior 316 of the platform 310. The attachment ring 410 is used to enable a user of the exercise device 300 to more easily access the resistance bands 320.

[0284] As shown in FIGS. 45 and 51, a user may attach a grasping member, such as a handle 420, to the end 400 of the resistance band 320 using the attachment ring 410. Additionally, a user may attach the handle 420 to multiple resistance bands 320 using the attachment rings 410 thereof in order to add further versatility to the functionality of the exercise device 300. The handle may be attached to one or more of the attachment rings using a carabineer or other mechanism.

[0285] As shown in FIGS. 45 and 51, the handle 420 is a grasping member that may be most easily graspable by a user with his or her hands. However, it is also within the scope of the present invention that a grasping member attached to one or more attachment rings 410 may take any form that might be preferred to allow the user to grasp the member with other appendages, such as an arm or foot. For example, as shown in FIG. 52, the grasping member may be a strap 422 configured to wrap around or secure to the user's foot. As shown, the strap 422 may include a clasp 424 to secure the strap 422 into a proper use position and to permit adjustment of the strap 422.

[0286] As indicated above, each end 356 of the platform 310 has three resistance bands 320 exiting therefrom for a total of six resistance bands 320 available in the exercise device 300. The resistance bands 320 are connected with vertical pulley shafts 366 that are aligned at opposite ends 356 of the platform 310.

[0287] More particularly, a plurality of vertical pulley shafts 366 transect the interior of the platform 310 at either end 356 thereof. The anchor end 402 of each resistance band 320 is anchored to a pulley shaft 366 at the same end 156 of the platform 310 from which the exiting end 400 of the resistance band 320 exits.

[0288] Following a single exemplary resistance band 320, the anchor end 402 of the resistance band 320 is anchored to a pulley shaft 366 at one end 356 of the platform 310. The resistance band 320 then travels longitudinally across the interior 316 of the platform 310 to a second pulley shaft 366 at the opposite end 356 of the platform 310. The resistance band 320 is partially wrapped around the second pulley shaft 366 such that the resistance band 320 makes approximately a 180° turn around the second pulley shaft 366. The second pulley shaft 366 has a pulley mechanism 404 disposed in surrounding relation thereto that freely rotates around the second pulley shaft 366. The pulley mechanism 404 enables the resistance band 320 to easily change direction and turn around the second pulley shaft 166. After extending around the second pulley shaft 366 and its associated pulley mechanism 404, the resistance band 320 travels longitudinally back across the platform 310 in the opposite direction from which it initially transects the platform 310. The exiting end 400 of the resistance band 320 then exits the platform interior 316 through its designated opening 354.

[0289] Two vertical rollers 406 are disposed in the opening 354 on either side of the resistance band 320, and a horizontal roller 407 is disposed above the resistance band 320. Such rollers facilitate smooth expansion and contraction of the resistance band 320 out of and in to the interior 316 of the platform 310. The smooth movement makes exercising with the resistance band 320 more comfortable, i.e., less jerky. The rollers 406,407 also are believed to significantly increases the useful life of the resistance band 320 by reducing friction of the resistance band 320 at the opening 354 during expansion and contraction.

[0290] Each of the six resistance bands 320 follows the path described above for an exemplary resistance band 320. Because the platform 310 has three resistance bands 320 exiting (and initiating) from one end 356 and three resistance bands 320 exiting (and initiating) from the opposite end 356, there is some functional overlap for the shafts 366. More particularly, for four of the resistance bands 320, the anchor pulley shaft 366 for a first resistance band 320 also serves as the second pulley shaft 366 for a second resistance band 320 that initiates at the opposite end 356 of the platform 310 from the first resistance band 320. The resistance bands 320 are arranged in the resistance band assembly 318 such that the functional overlap of the pulley shafts 366 does not interfere with the functionality of the resistance bands 320. Rather the arrangement of the resistance band assembly 318 enables maximum functionality while maintaining a compact size, which is desirable for the exercise device 300.

[0291] It furthermore is contemplated that the resistance bands 320 at each end of the platform will have varying resistances so that varying amounts of strength or exertion are needed to engage and expand the respective resistance bands 320, and that each end of the platform will have a plurality of resistance bands that are the same as the plurality of resistance bands at the other end of the platform. The resistance band assembly 318 shown in FIG. 53 includes resistance bands 320 having varying levels of resistance. Such varying resistance at respective ends of the platform is accomplished by varying the thickness of the resistance bands, with a resistance band having a relatively greater thickness requiring more force to expand than a resistance band having a relatively lesser thickness.

[0292] Preferably, the resistance bands 320 may be situated within the platform 310 according to the corresponding degree of resistance. In this regard, resistance bands 320 with the least resistance may be positioned toward the front of the platform 310, resistance bands 320 with an intermediate level of resistance may be positioned centrally, and resistance bands 320 with the greatest resistance may be positioned toward the rear of the platform 310.

[0293] It is further contemplated that indicia indicating the relative strength or resistance level of the resistance bands 320 may be included on the platform 310. As shown in FIGS. 42 and 48, the indicia include schematic barbells of relatively smaller and larger sizing. In particular, a smaller barbell 426 may identify the side having resistance bands 320 with less resistance, and a larger barbell 428 may identify the side having resistance bands 320 with greater resistance.

[0294] In addition, it is contemplated that a user may combine more than one resistance band 320 when using the exercise device 300 to add further versatility to a workout using the exercise device 300. In particular, the handle 420 or strap 422 (as shown in FIGS. 45 and 52, respectively) may be attached to attachment rings 410 corresponding to any combination of resistance bands 320. In this regard, the user may vary the level of resistance beyond the pre-set level of resistance of each individual resistance band 320.

[0295] As will be explained in greater detail below, the exercise device 300 may be used for exercising a wide array of muscles. In particular, the exercise device 300 may be used with the platform 310 being fully supported by the frame 302, as shown in FIGS. 40-45. Here, the platform 310 of the exercise device 300 is in a stable or steady configuration. A user may sit, stand, or lie on the platform 310 to perform various exercise movements including cardiovascular exercises, strength training exercises, and/or stretching exercises. The user may engage and pull the resistance bands 320 on either end 356 of the platform 310 via a user interface, such as a handle 420 or strap 422 attached to the attachment rings with a carabineer. The user may pull the resistance bands 320 with his or her hands if it is desired to exercise some aspect of the upper body. In addition, the user may pull the resistance bands 320 with his or her legs if it is desired to exercise some aspect of the lower body. As indicated previously, the resistance bands 320 may have varying resistances thereby enabling a versatile exercise experience. In addition, more than one resistance band 320 may be connected to a user interface to further add to the versatility of the exercise device 300.

[0296] The frame 302 and the platform 310 may also be separated from one another for use individually, as will be explained in greater detail below. As shown in FIGS. 46-51, the platform 310 may be placed onto the ground in order to provide an unstable surface. Here, a user may also sit, stand, or lie on the platform 310 to perform various exercise movements. The exercises may vary significantly because the platform 310 is permitted to rock from side to side. The rocking motion may aid in strengthening a user's core muscles and in improving a user's balance. With the platform 310 separated from the frame 302, the user may still engage the resistance bands 320 on either end 356 of the platform 310 by holding the grasping member attached thereto, such as a handle 420 or strap 422, and pulling the resistance bands 320.

[0297] Further still, the frame 302 of the exercise device 310 may be used separately from the platform 310. In particular, the user may engage the frame 302 of the exercise device 300 with his hands to perform various exercises without interacting with the platform 310.

[0298] Like the exercise device 100, the frame 102 also may be positioned on top of the platform 110 for performing exercises with the exercise device 300 in this alternative, unstable configuration.

[0299] FIGS. 56-123 are directed to various methods of using the exercise device 300, including use of the platform 310 and the frame 302 independently of one another. As will be explained in greater detail below, the exercise device 300 may be used in a stable manner, where the platform 310 is supported by the frame 302 and remains stationary. Further, the platform 310 may be separated from the frame 302 to permit the platform 310 to be used in an unstable manner. In this regard, the arched base supports 312 the platform 310 so that the platform 310 is permitted to rock back and forth. Still further, the frame 302 may be used separately from the platform 310 to permit other types of exercises, and the frame 302 may be used in an unstable configuration in which the frame 302 is supported on top of the platform 310. The versatility of the exercise device 300 may thus be understood, whereby a user is able to have a complete workout experience covering a broad range of different muscle groups with a single exercise device.

[0300] With reference to FIG. 56, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands extended downwardly at his or her sides. The user may then raise each arm to a generally horizontal position in generally parallel disposition relative to the stepping deck 314 while keeping the elbow of each arm slightly bent, as shown in FIG. 56. The arms then may be lowered through the same motion in reverse, and the routine repeated.

[0301] As shown in FIG. 57, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may then position each arm in a generally vertical orientation at his or her respective sides, this position being defined as a starting position. Then, the user may raise a first arm out to the side and slightly forward, while keeping an elbow of the first arm slightly bent, until the first arm is generally vertically oriented. The first arm may then be lowered through the same motion in reverse to return to the starting position.

[0302] As shown in FIG. 58, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may then position each arm in a generally vertical orientation at his or her respective sides, this position being defined as a starting position. Then, the user may raise a first arm upward and across his or her chest, while keeping an elbow of the first arm slightly bent, until the hand of the first arm is proximate the shoulder of the second arm of the user. The first arm may then be lowered through the same motion in reverse to return to the starting position.

[0303] As shown in FIG. 59, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. In particular, the user may stand on the platform in such a way that if the user's arms are positioned in generally vertical orientations at his or her respective sides, then one of the plurality of resistance bands 320 will be crossed with another of the plurality of resistance bands 320. The user may then position his or her arms across his or her torso such that his or her hands are generally at a waist level in front of the user, this position being defined as a starting position. Then, the user may raise a first arm up and across his or her torso, while keeping the elbow of the first arm slightly bent, until the first arm is generally parallel to the stepping deck of the platform 310. The first arm may then be lowered through the same motion in reverse to return to the starting position.

[0304] As shown in FIG. 60, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may then position handles of the resistance bands 320 at a height that is level with his or her shoulders, this position being defined as a starting position. Then, the user may press the handles upward generally simultaneously, until the handles are above the user's head. The handles may then be lowered downward through the same motion in reverse to return to the starting position. Additionally, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may then position handles of the resistance bands 320 in front of his or her hips with his or her palms facing backward, this position being defined as a starting position. Then, the user may pull the handles upward, generally simultaneously, by bending his or her elbows, while keeping his or her hands close to his or her torso. This action may be continued until the handles are proximate the user's chin. The handles may then be lowered downward through the same motion in reverse to return to the starting position.

[0305] As shown in FIG. 63, a user may lie on the platform 310 of the exercise device 300 such that a portion of his or her upper back rests on the platform 310. The user may grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may then position the handles at a level that is equal to the user's chest proximate the arm pits of the user, this position being defined as a starting position. Then, the user may press the handles upward, generally simultaneously, until his or her arms are oriented generally vertically. The handles are then lowered downward through the same motion in reverse to return to the starting position.

[0306] As shown in FIGS. 64A and 64B, a user may lie on the platform 310 of the exercise device 300 such that a portion of his or her upper back rests on the platform 310. The user may grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may then position the handles above his or her chest with elbows straight, this position being defined as a starting position. Then, the user may lower the handles downward and outward through an arc, generally simultaneously, until his or her arms are oriented generally parallel to the stepping deck 314 of the platform 310. The handles may then be raised upward and inward through the same motion in reverse to return to the starting position.

[0307] As shown in FIG. 66, a user may sit on the platform 310 of the exercise device 300 such that a portion of the user's rear rests on the platform 310. The user may grasp handles corresponding to one or more of the resistance bands 320. The user may then position the handles at a level that is equal to the user's chest proximate his or her shoulders, this position being defined as a starting position. Then, the user may press the handles upward generally simultaneously, until his or her elbows are generally straight. The handles may then be lowered downward through the same motion in reverse to return to the starting position.

[0308] As shown in FIG. 67, a user may sit on the floor or ground with his or her knees generally straight and his or her feet pressed against the platform 310 of the exercise device 300. The user may grasp handles corresponding to one or more of the resistance bands 320. The user may position the handles proximate his or her ankles, this position being defined as a starting position. Then, the user may pull the handles toward his or her torso, generally simultaneously, until his or her elbows are bent at a generally 90° angle and his or her shoulder blades are contracted. The handles may then be returned through the same motion in reverse to return to the starting position.

[0309] As shown in FIG. 69, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may bend forward at his or her hips while preventing his or her back from rounding. The user may bend forward until his or her torso is generally parallel to the stepping deck of the platform 310. The user may then position the handles proximate the user's knees, this position being defined as a starting position. Then, the user pulls the handles toward his or her torso, generally simultaneously, until his or her elbows are bent at a generally 90° angle and his or her shoulder blades are contracted. The handles may then be returned through the same motion in reverse to return to the starting position.

[0310] As shown in FIG. 70, a user may stand on the platform 310 of the exercise device 300 such that the distance between the user's feet is generally equal to the distance between the user's shoulders. The user may grasp handles corresponding to one or more of the resistance bands 320. The user may bend his or her knees slightly. The user may then position his or her arms each in a generally vertical orientation with elbows at a generally 90° angle and palms facing upward, this position being defined as a starting position. Then, the user may pull up by bending at the elbows and curling the handles until the handles are proximate the user's shoulders. The handles may then be lowered through the same motion in reverse to return to the starting position. Additionally, a user may stand on the platform 310 of the exercise device 300 such that the distance between the user's feet is generally equal to the distance between the user's shoulders. The user may grasp handles corresponding to one or more of the resistance bands 320. The user may then position his or her arms each in a generally vertical orientation with elbows bent at a generally 90° angle and with palms facing inward, this position being defined as a starting position. Then, the user may pull up by bending at the elbows and curling the handles until the handles are proximate the user's shoulders. The handles may then be lowered through the same motion in reverse to return to the starting position.

[0311] As shown in FIG. 79, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may bend forward at his or her hips while keeping his or her back from rounding. The user may bend forward until his or her torso is generally parallel to the stepping deck of the platform 310. The user may then position the handles proximate his or her ankles, this position being defined as a starting position. Then, the user may straighten at the hips while keeping his or her back straight. The user may then undergo the same motion in reverse to return to the starting position.

[0312] As shown in FIG. 84, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may stand with knees slightly bent with the handles at a height that is level with the user's shoulders, this position being defined as a starting position. Then, the user may bend his or her knees until the knees are bent at a generally 90° angle. The user may then straighten his or her knees through the same motion in reverse to return to the starting position. Additionally, a user may stand on the platform 310 of the exercise device 300 and grasp handles corresponding to one or more of the resistance bands 320 with his or her hands. The user may stand with knees slightly bent with the handles at a height that is level with a portion of the user's torso, this position being defined as a starting position. Then, the user may bend his or her knees until the knees are bent at a generally 90° angle.

[0333] As shown in FIG. 81, the user may stand on the platform 310 of the exercise device 300 and secure a strap corresponding to one or more of the resistance bands 320 to the foot of a working leg. The user may bend the working leg behind the user's body at the knee while keeping the knee in line with the user's hip.

[0334] As shown in FIG. 123, the user may position the user's hands and knees on the platform 310 of the exercise device 300 and secure a strap corresponding to one or more of the resistance bands 320 to the foot of a working leg. The user may then extend the working leg back and up in one motion while simultaneously straightening the knee of the working leg.

[0335] As will be understood, the exercise device 300 may also be used to exert muscles through exercises such as lunging, stepping, jumping, and hopping. FIG. 85 depicts a user performing a forward lunge exercise with a single leg. FIG. 87 depicts a user performing a lateral lunge exercise with a single leg. FIGS. 92 and 93 depict a user performing a reverse lunge exercise. As shown in FIG. 92, the user may begin in a standing position with both feet on the platform 310. The user may step back with one foot so that the foot is positioned flatly on the floor or ground, while bending the other knee to a generally 90° angle. The user then returns the foot back to the platform 310 and returns to a standing position. As shown in FIG. 93, a user may begin in a standing position with both feet on the platform 310. The user may step back with one foot so that the user's toes touch the floor or ground, while bending the other knee to a generally 90° angle. The user then returns the foot back to the platform 310 and returns to a standing position. In each lunging exercise, the user may repeat the exercise several times, or in combination with other exercises, as might be required for a particular workout.

[0336] FIGS. 88-91 depict a user performing various step exercises with the exercise device 300. As shown in FIG. 88, a user may perform a basis step exercise, by stepping on and off of the platform 310 with one foot at a time. As shown in FIG. 89, a user may perform a step exercise, where the user raises his or her knee while stepping on and off of the platform 310 with one foot at a time. As shown in FIG. 90, a user may perform a step exercise while standing on the platform 310, where the user alternates between raising each knee while stepping. In exercises where the user raises his or her knee, the knee may be raised such that his or her thigh is generally parallel to the stepping deck of the platform 310 when the knee is bent. As shown in FIG. 91, a user may perform an “over the top” step exercise where the user steps onto and over the platform 310 one foot at a time. In particular, a user may position the first foot on the platform 310 followed by the second foot. Once standing on the platform 310, the user may then step off of the platform 310 on the opposite side thereof beginning with the first foot followed by the second foot. In each stepping exercise, the user may repeat the exercise several times, or in combination with other exercises, as might be required for a particular workout.

[0337] FIGS. 94-99 depict a user performing various jump exercises with the exercise device 300. FIG. 94 depicts a user performing a forward jump exercise onto the platform 310. FIG. 95 depicts a user performing a lateral jump exercise onto the platform 310. FIG. 98 depicts a user performing a single leg jump exercise, where the user may jump from the floor or ground and land on the platform 310 with a single leg. As shown in FIG. 96, a user may perform an exercise where the user begins with a first foot on the floor or ground and a second foot supported by the platform 310. The user may then quickly push off from the platform 310 and alternate the position of his or her feet during the jump so that the first foot is supported by the platform 310 and the second foot is on the floor or ground. As shown in FIG. 97, a user may perform an exercise where the user may stand at one side of the exercise device 300 with a first foot on the floor or ground and the second foot supported by the platform 310. The user may bounce quickly with the foot on the floor or ground before jumping. During the jump, the user may switch the position of his or her feet so that the first foot is supported by the platform 310 and the second foot is on the floor or ground at the other side of the exercise device 300. As shown in FIG. 99, a user may perform an exercise where the user stands with a first foot on the floor or ground and a second foot supported by the platform 310. The user may then jump and land with the first foot supported by the platform 310 and the second foot on the floor or ground. In each jumping exercise, the user may repeat the exercise several times, or in combination with other exercises, as might be required for a particular workout.

[0338] Advantageously, a broad range of exercises may be performed with either of a stable surface or an unstable surface. The exercises set forth above are described with a user using the exercise device 300 having a stable surface, where the platform 310 is supported by the frame 302. It should also be appreciated that each of the exercises set forth above may also be performed in connection with an unstable surface.

[0339] In this regard, the platform 310 may be separated from the frame 302 and placed on the floor or ground with the arched base 312 in contact with the floor or ground. As such, the user may then use the platform 310 of the exercise device 300 in order to provide an unstable surface that further enhances the versatility of the exercise device 300. For many of the exercises set forth above, performance by a user in connection with an unstable surface may also enhance the difficulty of the exercise and may increase the range of muscle groups that are engaged with each exercise.

[0340] The exercise device may also be used in connection with pushup exercises. To enhance pushup exercises with an unstable surface, the platform 310 may be separated from the exercise device 300 to create such an unstable surface. FIGS. 100-102, 105-111, and 121-122 depict a broad range of different push-up exercises that may be performed with the platform 310 or the frame 302.

[0341] As shown in FIG. 100, a user may position his or her elbows on the platform 310 and position his or feet on the floor or ground. The user may then raise his or her hips such that the user's feet, hips, and head are generally in a straight line. Additionally, a user may position his or her elbows on the platform 310. The user may position one foot on the floor or ground and the other foot in the air. The user may then raise his or her hips such that the user's feet, hips, and head are generally in a straight line.

[0342] As shown in FIG. 101, a user may position one elbow on the platform 310 and place a side of one foot on the floor or ground. The user may then raise his or her hips such that the user's foot, hips, and head are generally in a straight line.

[0343] As shown in FIG. 102, a user may position a knee, hand, and foot on the platform 310. The user may then extend the other arm outward in front of his or her body and the other leg outward behind his or her body.

[0344] As shown in FIG. 105, a user may position a portion of his or her upper back against the floor or ground. The user may then position one foot on the platform 310 with the knee being bent. Then, the user may position the other foot in the air with the knee being generally straight. The user may then press his or her hips upward.

[0345] As shown in FIG. 106, a user may position one hand generally more forward on the platform 310 and position the other hand generally more backward on the platform 310. The user may then perform a pushup exercise.

[0346] As shown in FIG. 107, a user may position both hands on the platform 310. The user may then perform an oblique pushup exercise, where the user's feet are positioned side by side behind the user's body and against the surface of the floor or ground.

[0347] As shown in FIG. 108, a user may position both feet on the platform 310 and position both hands on the surface of the floor or ground. The user may then perform a “T” pushup exercise, where the user raises one arm off of the floor or ground and rotates his or her body until the arm creates a straight line overhead with the user's body.

[0348] As shown in FIG. 109, a user may position both feet on the platform 310 and position both hands close together on the surface of the ground. The user may then perform a close-handed pushup exercise, where the user lowers his or her body to the floor or ground while his or her hands are positioned close together.

[0349] As shown in FIG. 110, a user may position both feet on the platform 310 and position both hands on the floor or ground such that the digits of each hand form a diamond shape when positioned together. The user may then perform a pushup exercise, where the user lowers his or her body to the floor or ground while his or her hands are positioned to form the diamond shape.

[0350] As shown in FIG. 111, a user may position one foot on the platform 310 and the other foot in the air with both hands on the floor or ground. The user may then perform a pushup exercise.

[0351] As shown in FIG. 121, a user may position both hands on the platform 310 and place one foot on the floor or ground and the other foot in the air. The user may then perform a pushup exercise.

[0352] In each pushup exercise, the user may repeat the exercise several times, or in combination with other exercises, as might be required for a particular workout. Additionally, as can be appreciated, a user may also prefer to have a stable surface for use in connection with any of the pushup exercises set forth above. In this regard, the user may choose to attach the platform 310 to the frame 302 in order to provide such a stable surface. Alternatively, the user may choose to use the frame 302 alone for use in providing a stable surface for pushup exercises and other exercises. For example, FIG. 122 depicts a user performing a pushup exercise using the frame 302. In particular, in one contemplated pushup exercise, a user may position his or her hands at either end of the frame 302 and position his or her feet on the floor or ground. In accordance with another contemplated pushup exercise, the user may position his or her hands at either end of the frame 302 and position one foot on the floor or ground and the other foot in the air.

[0353] The various exercises set forth above may be performed in connection with a stable surface, as provided by the exercise device 300 or the frame 302, or with an unstable surface, as provided by the platform 310. Some exercises, discussed in greater detail below, are contemplated as providing a particular advantage to users when performed in connection with an unstable surface.

[0354] As shown in FIG. 104, a user may perform a single leg forward lunge using the platform 310 as an unstable surface. A user may stand with both feet on the floor or ground adjacent to the platform 310. The user may then lunge with one foot forward and place the foot on top of the platform 310. The user may bend his or her knee to about a 90° angle before pushing off to return to a standing position adjacent the platform 310.

[0355] FIGS. 103, 112, 117-118, and 120 depict various exercises that use the platform 310 as an unstable surface. In each exercise, the user stands on the platform 310 and may grasp handles corresponding to one or more of the resistance bands 320. The user may retain the handles at shoulder height with his or her elbows bent or at the sides of his or her body. In this position, the user may turn the palms of his or her hands to face outward. The user may then bend his or knees to about a 90° angle. As the user returns to a standing position, the user may curl or pull the handles such that each is raised approximately at shoulder height (as perhaps best shown in FIGS. 112 and 120). The user may then repeat the exercise. Additionally, the user may incorporate additional steps to the exercise or replace some of the steps with alternate steps. According to one step, the user may continue to raise the handles such that each handle is extended over the user's head. According to another step, the user may extend the handles outwardly away from his or her body in a lateral direction (as perhaps best shown in FIG. 118).

[0356] The exercises as set forth above may be repeated or combined with one another in order to develop a workout routine as might be preferred.
