BACKGROUND OF THE INVENTION

[0007] The benefits of exercise are numerous and well documented. For example, exercise can reduce the instance and severity of many diseases. In addition, exercise can make a person feel better about themselves and provide the user with increased self-confidence and feelings of self-worth. However, many would be exercisers are intimidated by complex fitness machines and uncomfortable and unnatural motions associated with exercising. In addition, they may be reluctant to use heavy weights which can cause injury to the user.

[0008] Fitness machines have been made in the past that eliminate the heavy weights by using resistance within materials, such as elastic materials. These can allow the user to vary resistance. However, this creates the side effect of creating "reactive-force". I.e., as the user performs the exercise movement, the resistance being used causes a reaction force into the user's body. The greater the resistance, the greater the reactive force.

[0009] Reactive force can cause damage to the user's body if the resistance is too strong for a user and the exercise movement becomes uncontrolled. Additionally reactive force can also accumulate a "break-down" effect in the ligaments, tendons or other soft tissues in the exercising user, and their associated muscle groups. Further, reactive force is a dissipated energy, and means less than optimal result to the exerciser, meaning a poor return on time and effort invested in the exercise.

[0010] Additionally, many exercise systems allow only a single resistance setting. I.e., the system allows for a single exercise at a single resistance. This does not allow the exercise system to be used by individuals of different fitness levels. In particular, some individuals will be too new to exercising to use the exercise system while other individuals will be too advanced. Only the small group in the middle will be able to use the system.

[0011] In addition, elastic materials can rebound if the material fails. I.e., as the elastic material is stretched, the force is stored in the material. When the material fails the force in the material can cause sudden and unpredictable movement, which has potential to injure the user or damage the equipment. This is an inherent danger of the materials and the ability to reduce or eliminate this danger is very limited. [0012] Further, many exercise systems use unnatural movements. I.e., they involve movements that the user does not perform when not doing that particular exercise. These unnatural movements can cause injury to the user. Often, the user will not even be aware of the injury until it becomes a major injury because they do not perform that movement unless exercising.

[0013] Accordingly, there is a need in the art for an exercise system which uses resistance that is not produced by elastic materials. Additionally, there is a need in the art for the exercise system to allow the user to select from variable resistance. Further, there is a need in the art for the system to prevent reactive forces from entering the user's body. Moreover there is a need for the exercise system to allow the user to exercise using natural movements.

DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS

[0032] Reference will now be made to the figures wherein like structures will be provided with like reference designations. It is understood that the figures are diagrammatic and schematic representations of some embodiments of the invention, and are not limiting of the present invention, nor are they necessarily drawn to scale.

[0033] Figure 1 illustrates an example of an exercise system 100. In at least one implementation, the exercise system 100 can be used to increase the physical fitness of a user. In particular, the exercise system 100 can allow the user to perform a variety of movements with varying resistance. The resistance can be provided through friction rather than elasticity which reduces or eliminates the reactive force transmitted to the user's body. I.e., the exercise system 100 can increase the user's physical fitness with a reduced chance of injury.

[0034] Figure 1 shows that the exercise system 100 can include a pulley 102. In at least one implementation, the pulley 102 can allow a force applied by the user in a first direction to be redirected in a second direction. An ideal pulley 102 would not add any force to the forces applied by the user. However, resistance can be added by making rotation of the pulley 102 more difficult, as described below. This can allow the user to vary the resistance of the exercise system 100.

[0035] Figure 1 also shows that the exercise system 100 can also include a cable 104. In at least one implementation, the cable 104 can move along the pulley 102. In particular, the user can apply a force to one end of the cable 104. The pulley 102 can redirect the force back to the user at the other end of the cable 104. Therefore, if the user moves one end of the cable 104, he/she can simultaneously resist the movement at the other end. Additionally or alternatively, the user can connect an external device which can provide resistance.

[0036] In at least one implementation, the cable 104 can include any material of sufficient strength to resist the forces applied by the user. For example, the cable 104 can be made of metal strands, ropes, nylon or any other material. Additionally or alternatively, the cable 104 can be of sufficient length to give the user freedom of movement. For example, the cable 104 can be between 2.1 and 3.3 meters long. E.g., the cable 104 can be approximately 2.7 meters long. As used in the specification and the claims, the term approximately shall mean that the value is within 10% of the stated value, unless otherwise specified. [0037] Figure 1 further shows that the exercise system 100 can include a first sling 106a and a second sling 106b (collectively "sling 106" or "slings 106"). In at least one implementation, the slings 106 can be attached to the ends of the cable 104. The user can use the slings 106 to apply force to the cable 104. For example, the user can hold the cable 104 in his/her hands or can place a body part in the sling 106, such as a foot or leg in the sling 106.

[0038] Figure 1 additionally shows that the exercise system 100 can include an attachment 108. In at least one implementation, the attachment 108 can connect the sling 106 to the cable 104. For example, the attachment 108 can include a clip and ring. The clip can be any device capable of hooking to the ring on the sling 106. For example, the hook can include a carabiner or other similar device.

[0039] Figure 1 also shows that the sling 106 can include a support 1 10. In at least one implementation, the support 1 10 can be configured to support the forces applied to the sling 106. In particular, the support 1 10 can be sufficiently strong to resist the forces of the user's exercise routine. For example, the support 1 10 can include a loop which allows the user to grip the support 1 10 or place a body part in the support 1 10. The support 1 10 can be of sufficient length and width to allow the user to use the sling 106. For example, the support 1 10 can be between 39 centimeters and 49 centimeters long and 3 centimeters and 5 centimeters wide. E.g., the support 1 10 can be approximately 44 centimeters long and 4 centimeters wide.

[0040] Figure 1 further shows that the sling 106 can include a body 1 12. In at least one implementation, the body 1 12 can increase the user's comfort. In particular, the body 1 12 can cover at least part of the loop created by the support 1 10. The body 1 12 can be wider and softer than the support 1 10. This can allow the forces to be spread out over the user's body, lowering the chances of injury to the user. For example, the body 1 12 can be between 30 centimeters and 38 centimeters long and 8 centimeters and 12 centimeters wide. E.g., the body 1 12 can be approximately 34 centimeters long and 10 centimeters wide.

[0041] Figure 1 additionally shows that the exercise system 100 can include an external attachment 1 14. In at least one implementation, the external attachment 1 14 can allow the pulley 102 to be mounted on an external device. Mounting the pulley 102 to an external device can allow the user to change the direction of the movement of the slings 106 in the exercise routine. [0042] Figure 1 also shows that the external attachment 1 14 can include a spring 1 16. In at least one implementation, the spring 1 16 can provide additional resistance to the exercise system 100. In particular, as a user performs the exercise routine, the spring 1 16 can allow limited movement of the pulley 102 toward the user. However, the spring 1 16 will provide a resistive force to the movement, increasing the difficulty of the user's exercise routine. Additionally or alternatively, the spring 1 16 can increase the user's comfort. In particular, the spring 1 16 can add some "give" to the exercise system 100.

[0043] Figure 1 further shows that the external attachment 1 14 can include an extension strap 1 18. In at least one implementation, the extension strap 1 18 can allow the user to select the position of the pulley 102. For example, the extension strap 1 18 can allow the user to attach the pulley 102 to a wall, ceiling or other structure. Additionally or alternatively, the extension strap 1 18 can allow the user to vary the angle of the pulley 102. For example, the extension strap 1 18 can allow the user to change the angle of the pulley 102 relative to an external structure.

[0044] Figure 1 additionally shows that the external attachment 1 14 can include a secondary attachment 120. In at least one implementation, the secondary attachment 120 can allow the user to connect the extension strap 1 18 to an external structure. The secondary attachment 120 can include a hoop, a loop, a carabiner or any other structure configured to allow the connection of the exercise system 100 to an external structure.

[0045] In at least one implementation, the exercise system 100 can be configured to electronically communicate with an external device. For example, the exercise system 100 can be connected to a computer, a smart phone, a gaming console or any other electronic device. The electronic device can monitor the user's movements and/or the effectiveness of the user's exercise routine. For example, the electronic device can measure the user's heart rate or provide feedback for the user's exercise routine. E.g., the electronic device can monitor the motion of the various parts of the exercise system 100 and inform the user regarding motion that is overextended or underextended or regarding motion that includes starts and stops or interruptions to the user's exercise routine. Additionally or alternatively, the electronic device can provide information over numerous exercise sessions or routines. For example, the electronic device can show the user's progress as the user increases in strength and health.

[0046] The exercise system 100 can connect to the external device using any communications means. For example, the exercise system 100 can be physically connected or can be wirelessly connected to the external device. Additionally or alternatively, the exercise system 100 can connect to the external device using a network. The network exemplarily includes the Internet, including a global internetwork formed by logical and physical connections between multiple wide area networks and/or local area networks and can optionally include the World Wide Web ("Web"), including a system of interlinked hypertext documents accessed via the Internet. Alternately or additionally, the network includes one or more cellular RF networks and/or one or more wired and/or wireless networks such as, but not limited to, 802.xx networks, Bluetooth access points, wireless access points, IP-based networks, or the like. For example, the network can include cloud based networking and computing. The network can also include servers that enable one type of network to interface with another type of network.

[0047] Figures 2A and 2B illustrate an example of a pulley 102. Figure 2A illustrates an example of a pulley 102 with low resistance; and Figure 2B illustrates an example of a pulley 102 with high resistance. In at least one implementation, the pulley 102 can be used as part of an exercise system. In particular, the pulley 102 can redirect forces applied by the user back to the user and/or provide resistance to the user's movement. I.e., the pulley 102 can allow the user to impart additional force to the user's own movement.

[0048] Figures 2A and 2B show that the pulley 102 can include a wheel 202. In at least one implementation, the wheel 202 can rotate about an axle 204. The rotation of the wheel 102 can, in turn, allow a connected to device to move. For example, a cable can be in contact with the wheel 102 such that movement of the cable results in rotation of the wheel 102 and vice versa, as described below. The rotational resistance of the wheel 102 can be varied to allow the rotation to become easier or more difficult, as described below.

[0049] Figures 2A and 2B also show that the wheel 202 can include a groove 206. In at least one implementation, the groove 206 can enhance the contact between the cable and the wheel 202. In particular, the groove 206 can increase the surface area of the contact between the cable and the wheel 202. Increasing the surface area of the contact can prevent slipping or other sudden movements of the cable which can be uncomfortable for the user. Additionally or alternatively, the groove 206 can ensure that the cable remains substantially centered relative to the wheel 202.

[0050] Figures 2A and 2B further show that the pulley 102 can include an attachment 208. In at least one implementation, the attachment 208 can allow the pulley 102 to attach to an external device. For example, the attachment 208 can be connected to the external attachment 1 14 of Figure 1 . Additionally or alternatively, the attachment 208 can be connected to an external structure, such as a wall, ceiling or floor, or to an external device, such as an exercise or weight machine. The attachment 208 can rotate relative to the wheel 202. This can allow the wheel 202 to be aligned in virtually any direction.

[0051] Figures 2A and 2B further show that the pulley 102 can include a resistance adjustment 210. In at least one implementation, the resistance adjustment 210 can control the resistance of the pulley 102. In particular, the resistance adjustment can control the resistance of the rotation of the wheel 202 around the axle 204 and the movement of the connected cable. Higher resistance can make for a more difficult exercise routine for the user, while lower resistance can make for an easier exercise routine for the user.

[0052] Figures 2A and 2B additionally show that the resistance adjustment 210 can include a brake extension 212. In at least one implementation, the brake extension 212 can prevent motion of the cable. In particular, the brake extension 212 can decrease the available space for the motion of the cable. I.e., the cable must pass between the wheel 202 and the brake extension 212. The smaller the space between the wheel 202 and the brake extension 212 the higher the resistance as the cable is trapped between the wheel 202 which rotating and the brake extension 212 which is stationary increasing the friction preventing motion of the cable.

[0053] Figures 2A and 2B also show that the brake extension 212 can be connected to the attachment 208. In at least one implementation, the attachment 208 can be used to adjust the position of the brake extension 212. In particular, as the attachment 208 is moved a first direction, the brake extension 212 can be moved closer to the wheel 202. In contrast, as the attachment 208 is moved in the opposite direction, the brake extension 212 can be moved further from the wheel 202. For example, the attachment 208 and brake extension 208 can be threaded through the housing of the pulley 102. The user can rotate the attachment 208 relative to the housing, inducing lateral movement of the attachment 208 and the brake extension 212.

[0054] Additionally or alternatively, the resistance adjustment 210 can include a brake bar. In at least one implementation, the brake bar can prevent motion of the cable. In particular, the brake bar can decrease the available space for the motion of the cable. I.e., the cable must pass between the wheel 202 and the brake bar. The smaller the space between the wheel 202 and the brake bar the higher the resistance as the cable is trapped between the wheel 202 which rotating and the brake bar which is stationary increasing the friction preventing motion of the cable.

[0055] Figures 2A and 2B also show that the resistance adjustment 210 can include an adjustment knob. In at least one implementation, the adjustment knob can be used to adjust the position of the brake bar. In particular, as the adjustment knob is moved a first direction, the brake bar can be moved closer to the wheel 202. In contrast, as the adjustment knob is moved in the opposite direction, the brake bar can be moved further from the wheel 202.

[0056] One of skill in the art will appreciate that the resistance adjustment 210 can include any mechanism which is configured to make movement of the cable more difficult. For example, the resistance adjustment 210 can include a mechanism that increases resistance to rotation of the wheel 202. E.g., the resistance adjustment can include a resistance tube. The resistance tube can be placed between the wheel 202 and the axle 204. Pressure can expand the resistance tube or otherwise make rotation of the wheel 202 relative to the axle 204 more difficult. The resistance adjustment can include further mechanisms such as those disclosed in the resistance chamber of U.S. application Ser. No. 13/109,654 filed on May 17, 201 1 , previously referenced. Additionally or alternatively, the resistance adjustment can include a screw or other mechanism that acts to decrease the space available for movement of the cable.

[0057] Figure 3 illustrates an example of a user 302 using the exercise system 100. In at least one implementation, the user 302 can use the exercise system 100 to tone or strengthen his/her muscles. In particular, the exercise system 100 recreates natural movements of the human body, allowing the user 302 to exercise with little or no detrimental impact to the body of the user 302. I.e., the exercise system allows the user 302 to exercise using natural movements and low impact resistance.

[0058] Figure 3 shows that the user 302 can hold the exercise system 100 using the slings 106. In at least one implementation, the user 302 can place one hand on the first sling 106a and the other hand on the second sling 106b. As the user 302 attempts to move the slings 106, the resistance provided by the pulley 102 to movement of the cable 104 can provide resistance to the movement of the slings 106.

[0059] Figure 3 also shows that as the user 302 moves the first sling 106a the second sling 106b moves in an equal but opposite direction and vice versa. I.e., the force applied by the user 302 to the first sling 106a is transmitted by the cable 104 to the pulley 102 which redirects the force to the second sling 106b, and vice versa. For example, if the user 302 pulls on the first sling 106a then the second sling 106b moves away from the user 302. Therefore, an additional component of resistance is imparted by the user 302. Additionally or alternatively, additional resistance can be imparted by an external device, such as the spring 1 16 or an additional exercise system or weight machine, or resistance to movement of the pulley 102, as described above.

[0060] Figure 4 illustrates an alternative example of a user 302 using the exercise system 100. One of skill in the art will appreciate that the exercise system 100 can be used by the user 302 to perform any number of exercises. The examples provided herein are intended to be illustrative only and are not limiting unless otherwise specified in the claims.

[0061] Figure 4 shows that the user 302 can place his/her feet in the slings 106. In at least one implementation, the user 302 can place one foot the first sling 106a and the other foot in the second sling 106b. As the user 302 attempts to move the slings 106, the resistance provided by the pulley 102 to movement of the cable 104 can provide resistance to the movement of the slings 106.

[0062] Figure 4 also shows that as the user 302 moves his/her first foot, the forces is imparted to the user's second foot and vice versa. I.e., the force applied by the foot of the user 302 to the first sling 106a is transmitted by the cable 104 to the pulley 102 which redirects the force to the second sling 106b and the second foot of the user 302, and vice versa. For example, if the user 302 pulls on the first sling 106a then the second sling 106b moves away from the user 302. Therefore, an additional component of resistance is imparted by the user 302. Additionally or alternatively, additional resistance can be imparted by an external device, such as the spring 1 16 or an additional exercise system or weight machine, or resistance to movement of the pulley 102, as described above.

[0063] In at least one implementation, the user 302 can use a supplemental exercise device, such as a vertical movement vibrating exercise and wellness platform. An example of a vertical movement vibrating exercise and wellness platform is disclosed in U.S. application Ser. No. 13/109,658 filed on May 17, 201 1 , previously referenced. In particular, the user 302 must balance himself/herself while performing the exercise routine with the exercise system 100, making the exercise routine more difficult and, consequently, more beneficial to the user.

[0064] Additionally or alternatively, the user 302 can use a supplemental exercise device, such as a tri-circular exercise device. An example of a tri-circular exercise device is described below. In particular, the user 302 can balance himself/herself on the secondary plates or the main plate. However, the secondary plate and/or the main plate are rotating. Therefore, the user 302 must control the movement of the slings 106 while directing the rotation of the secondary plates and/or the main plate, making the exercise routine more difficult and, consequently, more beneficial to the user.

[0065] Additionally or alternatively, the user 302 can use other supplemental exercise devices, such as weights or other exercise systems, while using the exercise system 100.

[0066] Figures 5A and 5B illustrate an example of an exercise system 500. Figure 5A illustrates a top perspective view of the exercise system 500; and Figure 5B illustrates a bottom view of the exercise system 500. In at least one implementation, the exercise system 500 can be used to increase the physical fitness of a user. In particular, the exercise system 500 can allow the user to perform a variety of movements with varying resistance. The resistance can be provided through friction rather than elasticity which reduces or eliminates the reactive force transmitted to the user's body. I.e., the exercise system 500 can increase his/her physical fitness with a reduced chance of injury. [0067] Figures 5A and 5B show that the exercise system 500 can include a foundation 502. In at least one implementation, the foundation 502 can be configured to support the exercise system 500. In particular, the foundation 502 can rest or be attached to a surface. The foundation 502 can then support the exercise system 500 relative to the surface. Additionally or alternatively, the foundation 502 can provide a stable resting place for the exercise system 500. I.e., the foundation 502 can prevent the exercise system 500 from tipping or falling over while in use.

[0068] Figures 5A and 5B also show that the exercise system 500 can include a main plate 504. In at least one implementation, the main plate 504 is configured to rotate relative to the foundation 502. In particular, the foundation 502 can form a plane and the main plate 504 can be in a plane approximately parallel to the foundation 502. The main plate 504 can rotate within the plane formed by the main plate 504. As used in the specification and the claims, the term approximately shall mean that the value is within 10% of the stated value, unless otherwise specified.

[0069] In at least one implementation, the main plate 504 can be attached to the foundation 502. The connection between the main plate 504 and the foundation 502 can allow for resistance to the rotation of the main plate 504. The amount of resistance can be adjusted by the user in order to increase or decrease the difficulty of the user's workout, as described below. The main plate 504 can be round to help ensure smooth rotation or can be other shapes, such as hexagonal, as desired by the user.

[0070] Figures 5A and 5B further show that the exercise system 500 can include a first secondary plate 506a and a second secondary plate 506b (collectively "secondary plates 506"). In at least one implementation, the secondary plates 506 are attached to the main plate 504. The secondary plates 506 are able to rotate about the attachment point of the secondary plate to the main plate 504. I.e., even as the main plate 504 rotates relative the foundation 502, the secondary plates can rotate relative to the main plate 504, as described below.

[0071] In at least one implementation, the attachment between the secondary plates 506 and the main plate 504 can allow for resistance to the rotation of the secondary plates 506 or the attachment can be designed to be relatively resistance free. The amount of resistance can be adjusted in a manner similar to the adjustment in the resistance of the rotation of the main plate 504 relative to the foundation 502. The secondary plates 506 can be round to help ensure smooth rotation or can be other shapes, such as hexagonal, as desired by the user.

[0072] Figures 5A and 5B additionally show that the exercise system 500 can include a stand 508. In at least one implementation, the stand 508 can provide a user with leverage during an exercise routine. Additionally or alternatively, the stand 508 can be used to support the user. The stand 508 can be attached to the foundation 502. Additionally or alternatively, the stand 508 and the foundation 502 can be a single piece of material, without restriction unless otherwise specified in the claims.

[0073] Figures 5A and 5B also show that the exercise system 500 can include a handle 510. In at least one implementation, the handle 510 can provide leverage to a user during an exercise routine. For example, the user can grip the handle 510 while twisting his/her core and/or lower body. This can provide a stable location for the user's hands, providing leverage for moving other body parts. Additionally or alternatively, the handle 510 can include grips, straps or other supplementary devices to help the user maintain his/her grip.

[0074] Figures 5A and 5B further show that the handle 510 can include a first grip 512a and a second grip 512b (collectively "grips 512"). In at least one implementation, the grips 512 can prevent the user's hands from slipping off the handle 510. For example, the grips 512 can include a non-slip material, such as rubber or plastic, or features, such as finger grooves, that assist the user in retaining his/her hold on the handle 510.

[0075] In at least one implementation, the exercise system 500 can be configured to electronically communicate with an external device. For example, the exercise system 500 can be connected to a computer, a smart phone, a gaming console or any other electronic device. The electronic device can monitor the user's movements and/or the effectiveness of the user's exercise routine. For example, the electronic device can measure the user's heart rate or provide feedback for the user's exercise routine. E.g., the electronic device can monitor the motion of the various parts of the exercise system 500 and inform the user regarding motion that is overextended or underextended or regarding motion that includes starts and stops or interruptions to the user's exercise routine. Additionally or alternatively, the electronic device can provide information over numerous exercise sessions or routines. For example, the electronic device can show the user's progress as the user increases in strength and health.

[0076] The exercise system 500 can connect to the external device using any communications means. For example, the exercise system 500 can be physically connected or can be wirelessly connected to the external device. Additionally or alternatively, the exercise system 500 can connect to the external device using a network. The network exemplarily includes the Internet, including a global internetwork formed by logical and physical connections between multiple wide area networks and/or local area networks and can optionally include the World Wide Web ("Web"), including a system of interlinked hypertext documents accessed via the Internet. Alternately or additionally, the network includes one or more cellular RF networks and/or one or more wired and/or wireless networks such as, but not limited to, 802.xx networks, Bluetooth access points, wireless access points, IP-based networks, or the like. For example, the network can include cloud based networking and computing. The network can also include servers that enable one type of network to interface with another type of network.

[0077] Figure 6 illustrates a top perspective view of an example of a main plate 504. In at least one implementation, the main plate 504 can rotate during an exercise routine. In particular, the user can user his/her core muscles to apply a force on the main plate 504. The main plate 504 can rotate as result of the applied force. Additionally or alternatively, the resistance to rotation of the main plate 504 can be adjusted by the user, as described below.

[0078] Figure 6 shows that the main plate 504 can include a primary rotator house 602. In at least one implementation, the primary rotator house 602 can allow at least a portion of the main plate 504 to rotate. In particular, as the main plate 504 is rotated about the primary rotator house 602, the user is forced to user his/her core muscles to control the rotation. This can help increase the user's core muscle strength.

[0079] In at least one implementation, the main plate 504 can include an indent or other feature for receiving the primary rotator house 602. In particular, the top of the primary rotator house 602 can be lower than the top surface of the main plate 504. An indent can allow for the attachment between the main plate 504 and the external structure to reside completely or partially below the top surface of the main plate 504, which prevents the attachment mechanism from interfering with the user's exercise routine.

[0080] Figure 6 also shows that the primary rotator house 602 can include a hole 604. In at least one implementation, the hole 604 can allow for an attachment between the main plate 504 and an external structure, such as the foundation 502 of Figure 5. A portion of the attachment can be inserted through the hole 604 while another portion rests on the primary rotator house 602. The can apply pressure to the primary rotator house 602, securing the main plate 504 to the external structure. The attachment can provide resistance to rotation of the main plate 504, as described below.

[0081] Figure 6 further shows that the main plate 504 can include a first secondary rotator house 606a and a second secondary rotator house 606b (collectively "secondary rotator houses 606"). In at least one implementation, the secondary rotator houses 606 can allow for a secondary plate, such as the secondary plates 506 of Figure 5, to be attached to the main plate 504. Additionally or alternatively, the secondary rotator houses 606 can allow the attached secondary plate to rotate about the secondary rotator house 606.

[0082] Figure 6 additionally shows that the first secondary rotator house 606a and the second secondary rotator house 606b can be approximately equidistant from the center of the main plate 504. I.e., the rotator houses 606 can be located on the dashed circle 608. The rotation of the main plate 504 can allow the secondary plates to rotate about any point on the dashed circle 608, as desired by the user.

[0083] Figure 7 illustrates side perspective view of an example of a main plate 504. In at least one implementation, the main plate 504 can support the weight of a user. In particular, the weight of the user can be distributed in any configuration on the main plate 504. Therefore, the main plate 504 must be of sufficient strength to support the weight of the user at any point, even along the circumference of the main plate 504.

[0084] Figure 7 shows that the main plate 504 includes a runner house 702. In at least one implementation, the runner house 702 is attached to the foundation 502. I.e., the runner house 702 does not rotate relative to the foundation 502 but is instead fixed in place relative to the foundation 502. The runner house 702 can be made of metal, polymers, plastic or any other suitable material. [0085] Figure 7 also shows that the main plate 504 includes one or more runners 704. In at least one implementation, the runner 704 is attached to the runner house 702. In particular, the runner 704 can include a wheel and an axle. The axle is attached to the runner house 702 such that the wheel can rotate about the axle. I.e., the axle can rotate relative to the runner house 702. Additionally or alternatively, the wheel can rotate relative to the axle.

[0086] Figure 7 further shows that the main plate 504 includes a runner indent 706. In at least one implementation, the runner indent 706 is configured to receive the axle of the runner 704. The runner indent 706 can attach to the axle of the runner 704 in a manner that allows the wheel of the runner to rotate freely. Additionally or alternatively, the runner indent 706 can provide sufficient space for the wheel to rotate about the axle as needed.

[0087] Figure 7 additionally shows that the main plate 704 can include a top plate 708. In at least one implementation, the top plate 708 rests on the runner 704. The top plate 708 can then move freely over the top of the runner 704. In particular, the runner 704 can support the circumference of the top plate 708 and allow the top plate 708 to move relative to the runner house 702. One of skill in the art will appreciate that any mechanism which supports the circumference of the top plate 708 and allows the top plate 708 to move relative to the runner house 702 is contemplated herein. For example, the main plate 504 can include ball bearings or other support devices.

[0088] Figure 8 illustrates an exploded view of an example of a resistance mechanism 800. In at least one implementation, the resistance mechanism 800 can be used to vary the resistance of the rotation of the main plate 504 of the exercise system. In particular, the resistance mechanism 800 can allow the user to set the resistance at any desired setting. For example, the user can increase the resistance for a more difficult workout or can decrease the resistance for an easier workout.

[0089] Figure 8 shows that the resistance mechanism 800 can include a resistance conduit 802. In at least one implementation, the resistance conduit 802 can provide friction which prevents the rotation of the main plate 504. Friction is the force resisting the relative motion of material elements sliding against each other. Friction is proportional to the normal force of the materials against one another. I.e., the higher the force of the main plate 504 against the resistance conduit 802 the higher the friction and the greater the resistance of the rotation of the main plate 504.

[0090] Figure 8 also shows that the resistance mechanism 800 can include a resistance spring 804. In at least one implementation, the resistance spring 804 can press the main plate 504 against the resistance conduit 802. As the spring presses the main plate 504 against the resistance conduit 802 with more force the resistance of rotation of the main plate 504 is increased. In contrast, as the resistance spring 804 presses the main plate 504 against the resistance conduit 802 with less force the resistance of rotation of the main plate 504 is decreased.

[0091] Figure 8 further shows that the resistance mechanism 800 can include a resistance knob 806. In at least one implementation, the resistance knob 806 allows the user to adjust the resistance created by the resistance mechanism 800. In particular, the resistance knob 806 can be turned to change the force of the resistance spring 804 on the main plate 504. The resistance knob 806 can include one or more markings to allow the user to determine the resistance. For example, the resistance knob 806 can include numbers or other markers which can allow the user to easily identify the amount of resistance.

[0092] In at least one implementation, the resistance knob 806 can move laterally with respect to the main axis of the main plate 504. For example, the resistance knob 806 can include threading or other elements which translate rotational movement into lateral movement. The resistance knob 806 can be turned a first direction to increase resistance and turned the opposite direction to reduce resistance. Additionally or alternatively, the resistance knob 806 can include a maximum point with rotation from that point in either direction reducing the resistance, and a minimum point with rotation from that point in either direction increasing the resistance.

[0093] Figure 9 illustrates an example of a user 302 using the exercise system 500. In at least one implementation, the user 302 can use the exercise system 500 to tone or strengthen his/her muscles. In particular, the exercise system 500 recreates natural movements of the human body, allowing the user 302 to exercise with little or no detrimental impact to the body of the user 302. I.e., the exercise system allows the user 302 to exercise using natural movements and low impact resistance. [0094] Figure 9 shows that the user 302 can stand on the exercise system 500. In at least one implementation, the user 302 is must balance himself/herself on the secondary plates 506. However, the secondary plates 506 and the main plate 504 are capable of rotating. Therefore, the user must user his/her muscles to maintain the proper motion and/or his/her balance. One of skill in the art will appreciate that the user 302 can place any body part on one or both of the secondary plates 506. For example, the user 302 can place his/her hands, feet or any other body part on one or both of the secondary plates 506.

[0095] In at least one implementation, the user 302 can use a supplemental exercise device, such as the exercise system using a variable resistance fitness chamber. An example of a variable resistance fitness chamber is disclosed in U.S. application Ser. No. 13/109,652 filed on May 17, 201 1 , previously referenced. In particular, the user 302 can balance himself/herself on the secondary plates 506 or the main plate 504 while using the exercise system using a variable resistance fitness chamber. However, the movement of the exercise system using a variable resistance fitness chamber can make it more difficult to direct the rotation of the secondary plates 506 and/or the main plate 504, making the exercise routine more difficult and, consequently, more beneficial to the user.

[0096] Additionally or alternatively, the user 302 can use a supplemental exercise device, such as a vertical movement vibrating exercise and wellness platform. An example of a vertical movement vibrating exercise and wellness platform is disclosed in U.S. application Ser. No. 13/109,658 filed on May 17, 201 1 , previously referenced. In particular, the user 302 can balance himself/herself on the secondary plates 506 or the main plate 504. However, the platform is moving up and down. Therefore, the user 302 must balance himself/herself while directing the rotation of the secondary plates 506 and/or the main plate 504, making the exercise routine more difficult and, consequently, more beneficial to the user.

[0097] Additionally or alternatively, the user 302 can use a supplemental exercise device, such as a variable-resistance functional fitness bag. An example of a variable-resistance functional fitness bag is disclosed in U.S. application Ser. No. 13/109,662 filed on May 17, 201 1 , previously referenced. In particular, the user 302 can balance himself/herself on the secondary plates 506 or the main plate 504 while using the exercise bag. However, the movement of the exercise bag can make it more difficult to direct the rotation of the secondary plates 506 and/or the main plate 504, making the exercise routine more difficult and, consequently, more beneficial to the user.

[0098] Additionally or alternatively, the user 302 can use other supplemental exercise devices, such as weights or other exercise systems, while using the exercise system 100. One of skill in the art will appreciate that the exercise system 100 can be used by the user 302 to perform any number of exercises. The examples provided herein are intended to be illustrative only and are not limiting unless otherwise specified in the claims.

[0099] Figure 10 illustrates an example of a user 302 using the exercise system 500 in combination with an exercise system 100. For example, the exercise system 100 can be attached to the exercise system 500. Additionally or alternatively, the exercise system 100 can be located near the exercise system 500.

[00100] Figure 10 shows that the user 302 can place his/her feet in the slings 106. In at least one implementation, the user 302 can place one foot the first sling 106a and the other foot in the second sling 106b. As the user 302 attempts to move the slings 106, the resistance provided by the pulley 102 to movement of the cable 104 can provide resistance to the movement of the slings 106. In particular, the user 302 can balance himself/herself on the secondary plates 506 or the main plate 504. However, the secondary plates 506 and/or the main plate 504 are rotating. Therefore, the user 302 must control the movement of the slings 106 while directing the rotation of the secondary plates 506 and/or the main plate 504, making the exercise routine more difficult and, consequently, more beneficial to the user.

[00101] Figure 10 also shows that as the user 302 moves his/her first foot, the forces is imparted to the user's second foot and vice versa. I.e., the force applied by the foot of the user 302 to the first sling 106a is transmitted by the cable 104 to the pulley 102 which redirects the force to the second sling 106b and the second foot of the user 302, and vice versa. For example, if the user 302 pulls on the first sling 106a then the second sling 106b moves away from the user 302. Therefore, an additional component of resistance is imparted by the user 302. Additionally or alternatively, additional resistance can be imparted by an external device, such as the spring 1008 or an additional exercise system or weight machine, or resistance to movement of the pulley 102, as described above.
