An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

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 exercise apparatus orienting foot pedals and handlebars having first and second rotating armatures for generating subtended paths of rotation, with motors to revolve the first and second rotating armatures in opposite directions and allowing the subtended paths to migrate from a first two-dimensional plane into a second two dimensional plane and back into the first two-dimensional plane.

A portable elliptical exercise apparatus where movement of the right pedal or left pedal defines an ellipse having an ellipse width and ellipse height, where the ellipse height can be incrementally varied according to the pedal surface location of a left foot or right foot on a corresponding left pedal or right pedal.

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.

Described herein is a swivel mount for rotatably coupling a display to the frame of an exercise machine. The swivel mount includes a rigid arm fixed to one of the display or the terminal end of a frame member, the arm terminating with a ball at its free end. A socket is defined at the other one of the display or frame member which rotatably received the ball. A rotational resistance mechanism is operatively associated with the socket to selectively engage the ball and resist the rotation of the swivel mount. In some embodiments, the arm of the swivel mount may rotate in a conical range of motion for repositioning the display in relation to the frame while the display remains in a fixed position relative to the arm.

An exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing the reciprocation path of movable components of the machine. In some examples, adjustment to an incline of the path of a reciprocating linkage may be achieved, for example by a lift assembly, the components of which may be arranged in a manner that provides a relatively compact form factor. In general, a more compact design may be achieved through the examples of the present disclosure, for example by co-axially locating a rotatable resistance element on the driven/input shaft.
