A foldable gymnastic machine comprising a supporting structure to rest said gymnastic machine on a resting surface, comprising a front portion, comprising in turn a resistance member, and a rear portion, an exercise device, through which a user performs a gymnastic exercise, coupled to said supporting structure and to said resistance member, capable of resisting during the execution of a gymnastic exercise, said exercise device comprising a second pair of levers for the feet, in turn comprising a first and a second lever, each provided with a first end, coupled to said supporting structure, and a free second end, capable of fitting said user's feet during the execution of the gymnastic exercise, said gymnastic machine being characterized in that said first and second lever of said second pair of levers for the feet are capable of passing from an open position, in which the user can perform the gymnastic exercise, to a closed position, when the gymnastic machine is not in use.

An elliptical trainer includes a machine table, a transmission unit, two pedal units and two suspension arms. Each pedal unit has a pedal rod and a guide. The pedal rod has a front end thereof pivoted to one respective crank arm, and an opposing rear end thereof pivoted to one respective pedal seat. The pedal seat has the top surface thereof bearing one respective pedal. Each suspension arm has two opposite ends of a bottom side thereof respectively pivoted to the machine table and the rear end of one respective pedal rod. Each suspension arm is skewed in the direction of the pedal, so that each suspension arm can guide the pedal forward along a straight line direction and backward along a diagonal direction.

An exercise machine is provided. The exercise machine may include a frame, an adjustment assembly coupled to the frame and selectively movable relative thereto, a foot linkage arranged to reciprocally move in a closed loop path, and a handle linkage arranged to reciprocally move in a defined path. The adjustment assembly may include a pivot axis. The foot linkage may be pivotably coupled to the adjustment assembly at the pivot axis such that selective movement of the pivot axis relative to the frame alters the closed loop path of the foot linkage in use. Movement of one of the foot linkage and the handle linkage may cause corresponding movement of the other of the foot linkage and the handle linkage Actuation of the adjustment assembly may selectively move the pivot axis in more than one direction.

An elliptical exercise machine may include a base, one or more upright stanchions coupled to the base and extending upward from the base and supporting first and second cranks. The first crank may support a first crank arm. The first crank arm may support a first pedal leg hanging downward from the first crank arm. The first pedal leg may support a right pedal. The right pedal may be configured to swing forward and rearward and to raise upward and lower downward. The second crank may support a second crank arm. The second crank arm may support a second pedal leg hanging downward from the second crank arm. The second pedal leg may support a left pedal. The left pedal may be configured to swing forward and rearward and to raise upward and lower downward.

Electromechanical rehabilitation of a user can include receiving a pedal force value from a pedal sensor of a pedal; receiving a pedal rotational position; based on the pedal rotational position over a period of time, calculating a pedal velocity; and based at least upon the pedal force value, a set pedal resistance value, and the pedal velocity, outputting one or more control signals causing an electric motor to provide a driving force to control simulated rotational inertia applied to the pedal.

An adjustable elliptical trainer is disclosed, which includes a body, a sliding rail, a connecting piece and a movement mechanism. The sliding rail has one end rotatably connected to the body around an axis and other end detachably connected to the body by the connecting piece along a longitudinal extension direction of the sliding rail. The movement mechanism includes a sliding part matched with the sliding rail, and the sliding part is provided on the sliding rail and is slidable along the sliding rail. The axis is perpendicular to the longitudinal extension direction of the sliding rail, a first connection point is provided at a joint between the connecting piece and the sliding rail, and a second connection point is provided at a joint between the connecting piece and the body, the connecting piece is configured to be movable relative to the sliding rail and/or the body.

An exercise machine may include a reciprocating linkage that supports one or more pedals configured to move in a closed loop (e.g., elliptical) path as a user exercises with the machine. The exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing an incline of a rail supporting the reciprocating linkage, and thus an angle of the closed loop path. The exercise machine may vary the incline with a lift mechanism operatively associated with the front upright frame of the machine, which may also support a resistance assembly, all in a compact form factor that may be more aesthetically pleasing and practical for relatively smaller exercise spaces.

An exercise device has a frame supporting guide links to which foot support links are pivotally attached. Upper pulleys are pivotally connected to the frame. Lower pulleys are connected to the foot support links. A vertical drive assembly is coupled to the foot support links by flexible elements. The flexible elements extend from the vertical drive assembly, about an upper pulley, about a lower pulley and to a second end connected to the frame.

In various embodiments, provided herein are systems, methods, processes, and devices for providing locomotive rehabilitation to a subject via one or more gait motions that substantially accurately mimic motions performed in healthy, natural gait cycles. The system may mimic natural gait motions via footplates and handles, and one or more linkage systems. In particular embodiments, the system may further include a motor unit and/or clutch for providing controlled forces assisting or resisting motions of a linkage system. Further, the system may include a tower for operating in a standing or seated position. In at least one embodiment, the system includes a body weight support system that provides offloading forces to a subject.

An exercise device includes a frame and a crank assembly. A pair of foot links each has a forward end, a rearward end, and a mid-portion. Each foot link has a crank attachment at the forward end that is connected the crank assembly. A foot receiving area is defined at the rearward end of each foot link. Each foot receiving area is longitudinally fixed with respect to the respective foot link and the mid portion of each foot link has a defined support location. The frame supports the support locations of the support links at a generally constant vertical height while allowing horizontal motion relative to the frame. The rearward length of the foot links is at least 1.5 times the forward length such that the foot receiving areas move in a path of travel having more vertical travel than horizontal travel.
