A stationary exercise machine in accordance with some examples herein may include a frame, a crankshaft rotatably supported by the frame, an upper moment-producing mechanism and a lower moment-producing mechanism both operatively engaged to the crankshaft to cause the crankshaft to rotate. The lower moment-producing mechanism and the upper moment-producing mechanism may be resiliently coupled to one another, such as via a resilient coupling between a crank arm of the lower moment-producing mechanism and a link or virtual crank arm or the upper moment-producing mechanism. The exercise machine may further include a measurement apparatus which may be configured to measure differential forces between the upper and lower mechanisms.

The present disclosure relates to a stair steppers, comprising a base, a bracket and a motion mechanism, the base supports the bracket, and the motion mechanism is disposed on the bracket, the bracket comprises a main body fixed to the base and a guide rail hinged to the main body, the guide rail is disposed to be inclined to the base, the motion mechanism comprises pedal links, pedals and pedal cranks, the pedal is disposed on the pedal link, the pedal link is hinged to the pedal crank, the pedal cranks are further hinged to the main body of the bracket, a hinge point of the pedal crank and the pedal link is disposed to be spaced apart from a hinge point of the pedal crank and the main body, the pedal link is provided with an abutting portion which abuts against the guide rail and is reciprocatingly movable along the guide rail. Since the guide rail is hinged to the main body, it is feasible to adjust an inclination angle of the guide rail relative to the base so as to change a movement trajectory of the pedal links and thereby adjust the difficulty of exercise of the stair steppers. When an angle between the guide rail and the base is larger, the difficulty of exercise is higher, otherwise, the difficulty of exercise is lower.

An exercise machine includes a frame, a movable element movably attached to the frame that is movable in the performance of an exercise, and a magnetic assembly attached to the frame. The magnetic assembly has a magnetic unit movably positioned adjacent to a non-ferromagnetic material.

A training bicycle, including a first frame (1, 36) configured to be supported on a floor, a second frame (2, 37) connected to the first frame, the second frame including an axle (4) allowing the second frame to tilt relative to the first frame along an axis in the longitudinal direction of the training apparatus, a handlebar (12, 35, 77, 90) connected to the upper end of a steering shaft (11, 76), the steering shaft being rotationally connected to the second frame, a crank (26, 110) connected to the second frame, and a first flywheel (22, 41, 56, 167, 193) rotationally connected to the lower end of said steering shaft with means for transferring movement from the crank to the first flywheel.

A multi-mode squat rack includes a frame, a support unit and a handle unit. The frame includes two struts pivotally connected to each other, two stepping boards connected to one of the struts, and a mount pivotally connected to the first strut. The support unit includes a seat post pivotally connected to the first strut, a seat supported on the seat post, a pair of ears supported on a side of the seat post near the first strut, at least one fin supported on an opposite side of the seat post, and an elastic unit arranged between the mount and the fin. The handle unit includes a stem pivotally connected to the first strut, a connection rod formed with an end pivotally connected to the stem and another end pivotally connected to the first strut or the pair of ears, and a handle connected to the stem.

An exercise device with a pair of upper links coupled to a frame and a pair of lower links pivotally and respectively coupled to the upper links is provided. A pedal is received on a distal end of each of the lower links. A transfer system between the pair of upper links may include a first and a second pushrod, each with a first end pivotally coupled to each respective upper link and a second end opposite to the first end. A first and a second damper arm, each pivotally coupled to the frame, may be included, each damper arm receiving a respective pushrod. An actuator may be coupled to the first damper arm and the second damper arm, thus providing movement of the first and second pushrods to alter a resting position of the first and second upper leg links with respect to the frame.

An exercise apparatus includes a base frame, a swing unit including a pair of swing arms pivotally mounted at the base frame, a pedal unit pivotally mounted at the swing unit, a travel path constraining unit including a pivot axle pivotally connected to the base frame, a pair of upper crank arms respectively affixed to two opposite ends of the pivot axle in reverse directions and a pair of links respectively pivotally connected between the upper crank arms and the swing arms for limiting the swinging range of the swing unit, a first damping unit for providing a damping resistance to the pedal unit, and a second damping unit for providing a damping resistance to the swing arms.

Various embodiments related to a recumbent therapeutic and exercise device are provided herein. The recumbent therapeutic and exercise device includes a frame; a hand crank system coupled to the frame, the hand crank system including a hand crank rotatable by a user, wherein the hand crank is movable in a substantially vertical plane closer to and further from a support surface for the frame; and a foot crank system coupled to the frame, the foot crank system including a foot crank rotatable by the user, wherein the foot crank is movable in a substantially horizontal plane relative to the support surface for the fame.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

An apparatus for gait training, comprising: a movable base (11) comprising a drive unit (13) for moving the movable base (11), an arm arrangement (15, 16, 18) extending from the movable base (11) to enable a person (113) to be at least partially suspended from above, a movement detector (14, 115; 20; 21) to detect a movement of the person (113), and a control unit (119) configured to control said drive unit (13) in response to movement of the person detected by the movement detector (14, 115; 20; 21) such that the movable base (11) follows the person (113) in a predetermined distance range and in a predetermined angular range with respect to a movement direction of the person (113). The apparatus may comprise a projector (112) configured to project a path to be taken by the person (113) and a securing mechanism (21) to secure the suspension of the person (113) in response to a fall or stumbling being detected by a fall detector (21).
