Abstract
Abstract An exercise apparatus includes a support member that is movable relative to a frame, and a force receiving member that is movable relative to the support member. A first end of the support member is pivotally connected to the frame, and a second, opposite end of the support member is supported on a crank. A flexible link is interconnected between the crank and the force receiving member. The crank, the roller, the support member, and the link cooperate to move the force receiving member in a desired path.
