A multifunctional chair is provided. The multifunctional chair includes a supporting body, a telescopic structure, a seat body, and a pedal assembly. The pedal assembly includes a fixing rod, a movable rod, an operation portion, and an elastic resistance member. The telescopic structure is connected to the supporting body and configured to be operated to telescopically move relative to the supporting body. One end of the fixing rod is fixed to the supporting body. The movable rod is movably connected to the fixing rod. The operation portion is arranged at an end of the movable rod away from the fixing rod. Two ends of the elastic resistance member are respectively connected to the supporting body and the fixing rod. A user can push against the operation portion to rotate the movable rod and the fixing rod toward the ground, and the elastic resistance member provides an elastic resistance.

An exercise apparatus for targeting the hip muscles is disclosed. The apparatus consists of a plurality of supports, a footboard, and a belt wherein elastic bands may be attached to the belt and to the base supports to provide resistance. The apparatus is fully adjustable for targeting muscles of interest, and collapsible for ready transport. Adjustable handles are optionally provided to maintain user stability and thus maximize the effectiveness of the exercise. A method of using the exercise equipment is also provided.

An exercise system includes a base module having a seat with a seat depth, and a vertically adjustable back configured to fixedly engage with the base module at a first seat depth and a second seat depth different from the first seat depth.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A compact, portable, lightweight, easily transportable leg press exercise apparatus to simulate both exercise and the daily activity of sitting in a microgravity environment. The exercise portion of the apparatus creates stress on the lower extremities by supplying a variable resistance to a reciprocating foot pedal by way of a coil spring and damper system acting through a four-bar linkage. The chair is adjustable in angle to fit each user and to simulate a force that is two-thirds of body weight. By combining resistance exercise and lower body negative pressure with the LBNP leg press exercise apparatus, the users experience one or more times body weight (BW) in stress on their musculoskeletal, cardiovascular and nervous systems. By achieving one times BW or greater (artificial gravity) during exercise and two-thirds BW during sitting, the gap between the precondition and post condition syndrome will become smaller.

An exercise device for alternating movement of arms and legs by which users perform alternating active exercises and passive exercises repetitively is revealed. The exercise device includes a base, a hand driving member, and a leg driving member. Both the hand and leg driving member are pivotally connected to the base while the leg driving member is arranged under the hand driving member. One end of the hand driving member and one end of the leg driving member are configured to be pivotally rotated on the base. The hand and leg driving members are pivotally connected by a linkage. By the pivotal connections of the above parts, the hand and leg driving members are linked and moved with each other so as to lift up or press down arms and legs for stretching. The stretching of arms and legs also generates pressure on the abdomen of the user to exercise his or her abdomen.

A permanently affixed and travelling selector pin, car and weight plate selection mechanism for use with physical fitness equipment is disclosed including a segmented track and/or cut out cavern within the plate body for the car to travel within in either vertically or horizontally in order to select a different weight plate or cumulatively, more or less weight for an exercise. The selector pin and car mechanism features a selector pin which is not removable from the car and is inserted through the car which is contained by the track and or plate body shape and into a throughbore in the weight plate in order to engage with the selector stem.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A locking device for an exercise system may include at least one moveable assembly that is in communication with a resistance mechanism. The locking device has an actuating device for selectively engaging the locking device, a locking member having a contact portion, wherein the contact portion of the locking member is not in contact with the resistance mechanism of the exercise system when the actuating device is in a first position, thereby allowing movement of the at least one moveable assembly, and wherein the contact portion of the locking member is in contact with the resistance mechanism of the exercise system when the actuating device is in a second position, thereby preventing movement of the at least one moveable assembly.

A ground-effect footplate against which a user applies plantar force and moves their foot in 3D across all seven lower-extremity biomechanical axes to accomplish specific as well as global ambulatory objectives related to lower extremity performance improvement, injury prevention and rehabilitation. A device comprising at least one articulating leg connected to a ground-effect footplate and a surface for a user to position against. The device can be used in conjunction with software to create virtual ambulatory environments that mimic GRFVs and cause moments of force that initiate muscular activations that substantially mimic human ambulation, and can couple those movements with non-functional movements in order to improve ROM, speed, strength, and proprioception.
