A fitness device includes a main body, a left wing extending outwardly from the main body in a first direction, and a right wing extending outwardly from the main body in a second direction opposite the first direction. A cable extends from the main body to each of the left wing and the right wing. The fitness device further includes a gearbox, a spool assembly connected to an input end of the gearbox, a brake assembly connected to an output end of the gearbox, and a pulley assembly.

A lightweight, portable leg strengthening apparatus includes a footplate and calf support which form a leg rest, a top a friction free sliding element running longitudinally along and supported on a rectangular base. The leg rest is hinged at its attachment to the sliding element to allow a longitudinal tilting movement. The leg rest has adjustability at the hinge point at the ankle to enable alterations in the foot position. The apparatus uses resistance material/rubber cords or springs attached via a plate to a steel cable, travelling via an aperture in the end of the device to the back of the sliding element a top the body of the device to create tension as the leg rest a top the sliding element is moved longitudinally along the body of the device. Resistance can be varied and progressed by using different numbers of resistance cords/springs.

An exercise device includes a frame, handlebars supported by the frame, and a computing device. The handlebars include a yoke that is movable relative to the frame, a biasing element positioned between the yoke and the frame, and a sensor configured to measure a movement of the yoke.

Hand held weight units of light weight manufactured as a solid unit, a shell unit with core insert combinations or modular units with interlocking ends. Shell units with core inserts and modular interlocking units allow for the changing of held weight by inserting or removing inserts or by locking or unlocking of modular weight unit sets creating varying held weight. The weight units are primarily used with upper body exercises during aerobic exercises in the home, outdoors, or in a gym setting such as walking or running to vary the intensity of workout during use.

A portable smart hand grip according to an embodiment of the present disclosure includes a first housing, a guide part combined with the first housing and including a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along first axis, a second track disposed on the pair of first tracks, and moving along the first axis, and formed along second axis, a hand holder disposed on the second track, and moving along the second track, and on which at least one of hand and arm of a user is held, a stopper for a track disposed on the pair of first tracks for limiting a movement range of the second track, and a stopper for a holder disposed on the second track for limiting a movement range of the second pair of first tracks, wherein the first axis and the second axis are disposed with an inclination.

The Hand Strengthener is a unique handheld exercise device that has manifold applications. The Hand Strengthener's design and utility is distinctive in several manners: Due to the device's non-uniform, contoured shape, the position and angle the user holds the device can strengthen and stretch different muscle and anatomy groups. The design's sphere shape fits in the users' palm for a comfortable, yet challenging handgrip on one side, while the two other contours allow for a uniquely different exercise experience for the users. Furthermore, the polyurethane material combined with the varied, and non-uniform shape allow for a therapeutic experience for the users. Our disclosures for research of competing devices clearly indicate a lack of multi purpose handheld devices with the Hand Strengthener's distinctive design, shape and contour.

A lever for use in a trampoline includes a frame attachment, a rigid element and a tensioner. The frame attachment is configured for connection to a supporting frame of the trampoline; the frame attachment includes a stop formation. The rigid element is connected to the frame attachment and is configured to pivot about a fulcrum connected to the frame attachment. The rigid element includes a lug configured to contact the stop formation to limit an extent of a pivot motion of the rigid element about the fulcrum. The rigid element comprises a jump mat end and a frame end, the jump mat end being configured for connection to a jumping mat. The tensioner is connected to the rigid element and is configured for attachment to the trampoline supporting frame.
