ABSTRACT:
An exercise device has left and right foot supports that are supported on respective pairs of pivoting rails that are constrained to remain parallel to one another. Left and right cranks move the rails relative to a frame, and move the foot supports along the rails in a manner that defines adjacent paths of generally elliptical foot motion, while maintaining the foot supports in a fixed orientation relative to the frame.
