Disclosed is a rehabilitation training apparatus including a pair of first tracks that are arranged in parallel at an interval, a second track that is perpendicular to the pair of first tracks and is movably connected to the pair of first tracks, a hand holder that is movably provided in the second track and on which a hand of the user is held, a holder driving unit that reciprocally moves the hand holder along the second track, and a track driving unit that reciprocally moves the second track along the pair of first tracks.

A cordless treadmill including a frame, a belt system. and a drop-in cartridge is disclosed. The cartridge includes a plurality of staggered rollers configured to provide tactile feedback to the user. The frame is adapted to receive the belt system and the cartridge as they are lowered into the frame, and the frame is adapted to place the belt of the belt system into tension as the belt system is lowered into the frame. An integrated flywheel generator system provides smooth operation of the treadmill and generates electricity to power additional systems.

According to an embodiment of the present disclosure, a left and right balancing system for a treadmill may comprise two detection devices respectively installed at a left and right side of the treadmill, detecting strengths of vibrations respectively at the left and right side of the treadmill when a user exercises on the treadmill, generating detection strength signals according to the detected strengths, and transferring the generated detection strength signals to the user, and a notification device receiving the detection strength signals from the detection devices and indicating the user's left and right balance state.

A trampoline comprising a trampoline mat defining a jumping area and supported via springs from a circumextending support structure, the support structure including a plurality of legs so that the trampoline mat is positioned at a height above ground or flooring; the trampoline being provided with a safety enclosure surrounding the jumping area. The safety enclosure comprises a net supported by a plurality of telescopically extendable poles, each pole when extended comprising a plurality of sections, each successive extended section with distance above the trampoline mat having a cross-section less than that that of the next less extended section whereby the sections nest when telescopically collapsed. The lowermost such section is supported at a position above the ground or flooring by the support structure.

A motor resistance control structure for an exercising apparatus comprises a motor, a drawing member, a control unit, and a sensing element. The control unit controls the motor to generate a resistance and outputs a first instruction to allow an output shaft to rotate by a first present revolution along a first sense of rotation. The drawing member receives an applied force and pulls the output shaft to rotate by a training revolution along the first sense of rotation. The sensing element senses the applied force and gets a sensing result. By the comparison of the applied force with the resistance, the control unit controls the output shaft to rotate by a second preset revolution along a second sense of rotation or release the resistance of the motor, which avoids a problem in an ordinary exercising apparatus that a counterweight may fall freely to injure a user.

A weighted-squat exercise machine comprises a pivotable, length-adjustable lever, a weight supported by said lever, a support base, and a hip-belt that connects a user to the machine. Weights are supported by the machine at a safe distance from a user. The weighted-lever has an angle with respect to the horizon with a range of from about 35 degrees to about 45 degrees. When a user wearing the hip-belt connects it to the weighted-lever, the weight's gravitational force is transferred to the user providing for the user to perform weighted squats in a safe manner as the weights are spaced from the user. Thus, athletes can safety exercise without a spotter even if using 1000 pound weights. The belt supports the weight about the athlete's hip structure so that there is no stress on the user's neck and spine and no restriction in breathing.

An upper limb exercise apparatus comprises a base, a frame, and a display mounted on the frame. The apparatus further comprises 5-bar linkage-type movable parts positioned on the display and including a first link and a second link. The first link comprises a 1-1 member having one end attached to the frame and being rotationally driven, and a 1-2 member having one end rotatably attached to the other end of the 1-1 member, the other end having attached thereto a handle for gripping. The second link comprises a 2-1 member having one end attached to the frame and being rotationally driven, and a 2-2 member having one end rotatably attached to the other end of the 2-1 member, the other end having attached thereto the handle and the other end of the 1-2 member. Series elastic actuators attached to the 1-1 member and the 2-1 member provide torque.

A bicycle trainer, including a base, permitting fore and aft movement and a frame, supported by the base. Also, a seat and a handlebar assembly and a pedaling assembly is supported by the frame. The handlebar assembly is rotatably engaged to the frame, and is supported by a tongue, that is hinged to the base so as to permit horizontal rotation, and the handlebar assembly is attached to the tongue at a position removed from the hinge. Turning the handlebars causes the frame to move laterally.

There is provided a plank exercise device including a support portion adapted to receive arms or hands of a person and adapted to receive a display device, a destabilizer connected to the support portion, and a stationary base adapted to hold the destabilizer.

A handheld resistance exercise device is contemplated for exercise, rehabilitation, warm-up and the like, which provides resistance to muscles, tendons, joints, and fasciae in the upper body and lower back as it is actuated by a user standing a distance away from a vertical surface that is engaged with the device. Actuation thereof by the user in performing various exercise protocols provides stability for one or more muscles of the hand, elbow, shoulder girdle, shoulder blade, rib cage, as well as the inner core muscles, while also providing improved mobility for one or more of the wrist, forearm, elbow, shoulder joint, and muscles that rotate and bend the spine sideways.
