1. An exercise apparatus, comprising:
- a frame designed to rest upon a floor surface;
a left crank and a right crank, wherein each said crank is rotatably mounted on the frame and rotatable about a crank axis;
a left crank support and a right crank support, wherein each said crank support is mounted on a respective crank at a radial distance from the crank axis, and the left crank support and the right crank support cooperate to define a crank diameter;
a left rail and a right rail, wherein each said rail is movably connected between a respective crank support and the frame in such a manner that a first end of each said rail is supported by a roller, and an opposite, second end of each said rail is pivotally connected to a pin;
a left rocker link and a right rocker link, wherein each said rocker link is pivotally mounted on the frame;
a left foot support and a right foot support, wherein each said foot support is rollably mounted on an intermediate portion of a respective rail and pivotally connected to a respective rocker link; and
a left cable assembly and a right cable assembly, wherein each said cable assembly links rotation of a respective crank to movement of a respective foot support through a range of motion which is twice the crank diameter.

Abstract
An exercise apparatus includes a crank rotatably mounted on a frame, and an axially extending support connected to the crank at a radially displaced location. A foot supporting member is movably interconnected between the axially extending support and the frame. A linkage assembly links rotation of the crank to movement of a foot platform through a generally elliptical path.
