Abstract
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. Both a force receiving member and a discrete support member are linked to the axially extending support in such a manner that rotation of the crank relative to the frame is linked to movement of the force receiving member in a generally elliptical path relative to the frame.
