Abstract
An exercise apparatus includes a frame, an arm driven member, a leg driven member, and a transmission interconnected between the arm driven member and the leg driven member. At least one of the arm driven member and the leg driven member is pivotally connected to the frame. The arm driven member and the leg driven member are operatively connected in such a manner that the two members are subject to independent influences but nonetheless synchronized with respect to direction of movement.
Claims21
An exercise apparatus, comprising:
- a frame designed to rest upon a floor surface;
- a left leg driven member and a right leg driven member, wherein each said leg driven member is movably connected to the frame;
- a left arm driven member and a right arm driven member;
- a means for interconnecting each said arm driven member and a respective leg driven member in such a manner that during movement of each said leg driven member through a leg stroke length, each said arm driven member is both synchronized with a respective leg driven member and movable through an arm stroke length which is variable independent of the leg stroke length.

An exercise apparatus, comprising:
- a frame designed to rest upon a floor surface;
- a left leg driven member and a right leg driven member, wherein each said leg driven member is movably connected to the frame;
- a left arm driven member and a right arm driven member;
- a means for connecting each said arm driven member and a respective leg driven member in such a manner that during movement of the respective leg driven member, the arm driven member is both (a) selectively movable relative to the frame, and (b) constrained to remain synchronized with the respective leg driven member when moving relative to the frame.

An exercise apparatus, comprising:
- a frame designed to rest upon a floor surface;
- a left leg driven member and a right leg driven member, wherein each said leg driven member is movably connected to the frame;
- a left arm driven member and a right arm driven member;
- and
- a means for connecting each said arm driven member and a respective leg driven member in such a manner that the arm driven member is constrained to always be in one of two modes, including a first mode fixed against movement relative to the frame, and a second mode constrained to move in synchronous fashion together with the respective leg driven member.
