Abstract
An exercise apparatus has a force receiving member movably interconnected between a crank and a frame with a degree of freedom for variable length exercise strokes as a function of user applied force.
Claims14
A method of facilitating elliptical exercise motion, comprising the steps of:
- providing a frame designed to rest upon a floor surface;
- mounting left and right cranks on the frame for rotation about a crank axis;
- and
- interconnecting left and right foot supporting linkages between the frame and respective said cranks for movement relative to the frame through respective closed curved paths of motion having a variable length stroke measured parallel to the floor surface and variable as a function of user applied force.
