A substantially rectangular, flexible foam-filled cushion, consists of three substantially rectangular, hingeably connected segments: a longest upper segment, which is configured to align with and support a user's upper torso, a shorter middle segment, which is configured to align with and support a user's pelvis/buttocks and upper legs, and a shortest lower segment, which is configured to align with and support a user's lower legs. From the top of the upper segment extends an elastic resistance cord. From the bottom of the lower segment extend two elastic resistance ankle straps and an elastic foot strap. The thickness and flexibility of the cushion are adapted to provide both resistance to bending of the cushion and support for the portion of the user's body engaged with the cushion during bending. Therefore, the cushion is adapted to play an active role in the exercise movements, along with its appended resistance bands. The cushion's ability to move cooperatively with the exercise movements is enhanced by the alignment of its hinges with the body's principal bending locations in the waist/lower back and knees.

A pedal system for tracking use of a cycle style exercise device. The pedal system includes a pedal with a shaft for coupling to the pedal crank of the exercise device and a housing that is rotatable about the shaft. An accelerometer positioned in the housing is configured to provide data about the movement of the pedal to a microcontroller. A wireless communication chip positioned in the housing is used to transmit the data about the movement of the pedal to a remote device via the wireless communication chip. The remote device is programmed to receive, display and track the data about the movement of the pedal.

The present disclosure relates to a chair with game features. A foldable chair includes a foldable structure having a back canvas structure, a bottom canvas secured to the foldable structure and having a through-hole, a cover flap removably connected to the bottom canvas covering the through-hole, and a back canvas removably secured to the back canvas structure. A field goal includes a plurality of pipes connected with a plurality of connection fittings. The back canvas can be removed so that the field goal can be removably connected to the back canvas structure. The cover flap can be moved from a first position covering the through-hole, and a second position where the through-hole is exposed. In some embodiments a foldable backboard can be removably connected to the back canvas structure.

An exercise device with a crank housing supporting a pedal crank having a pair of opposing pedals that are pivotally mounted to the pedal crank. A first strut extends from the crank housing and is jointed to a second strut by a coupling that selectively allows the struts to rotate relative to each other so that the device may be folded into a planar configuration or extended for use. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank. A telescoping arm may be used to interconnect the exercise device to a table or seat so that it can be folded and stored under the table or seat, and unstowed and unfolded for easy use.

A first strut extends from the crank housing and is jointed to a second strut by a coupling that selectively allows the struts to rotate relative to each other so that the device may be folded into a planar configuration or extended and locked into place for use of the pedal crank. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A strap may be coupled to one of the pair of legs for additionally securing the exercise device to an airline seat. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank.

A game system is disclosed that comprises a game processor configured to control game play of an electronic video game, and a game controller in electronic communication with the game processor. The game controller includes a plurality of appendicular members configured for respective engagement with legs and arms of a user, and a resistance control system providing a resistive force on each of the plurality of appendicular members with respect to movement of the legs and arms of the user. The resistive force provided by the resistance control system is adjustable in a generally continuous manner in response to the game play of the electronic video game. The game controller also includes a feedback control system responsive to at least one of a motion parameter, a force parameter, and/or a position parameter of each of the plurality of appendicular members to control the game play of the electronic video game.

An auxiliary device for muscle strength training is provided, which includes: a base; a sliding member slidingly coupled to the base; and a connecting-rod mechanism connected to the base and the sliding member in such a way that a positional shift of the sliding member allows the connecting-rod mechanism to rotate relative to the base and change its state. As such, the auxiliary device has first and second configurations to assist patients who are incapable of controlling their muscles by themselves to effectively train specific muscle groups. Further, elastic members are connected to the base and the connecting-rod mechanism and provide elastic potential energies so as to keep the auxiliary device in static equilibrium. The auxiliary device has a simple structure and is easily manufactured at a low cost and applicable for patients with muscle strength lower than grade 3.

A rocking chair provides abdominal exercise by user actuation of pivotal armrest handles that are configured to provide a crunch type exercise motion. The arrangement of internal pivot frames is such that armrest handle actuation shifts the user's center of mass both vertically and longitudinally, which in turn initiates a natural rocking motion by gravity. The inertial dynamics of the resulting motion are inherently kinesthetically pleasurable. The resistance is provided by the user's own body weight with variation through differential leverage. Alternatively, the configuration of the armrest handles is such that a user may benefit from an isometric exercise by simply holding them stationary in a conventional armrest position.

An exercise system includes a base module having a seat portion having a seat depth in a lengthwise direction from a front portion of the base module toward a rear portion of the base module, and an adjustable back module configured to fixedly engage with the base module at a first seat depth and a second seat depth different from the first seat depth in the lengthwise direction.
