Abstract

An exercise apparatus comprises: a frame having a base portion and having first and second right support elements and first and second left support elements; a crank system comprising first and second crank coupling locations, the crank system being supported by the frame; a right foot support member; a left foot support member; a right guide element coupled to the right foot support member and; a left guide element coupled to the left foot support member; a first flexible support system comprising a first flexible element, the first flexible element coupled to the first and second right support elements and the right guide element and coupled to the first crank coupling location; and a second flexible support system comprising a second flexible element, the second flexible element coupled to the first and second left support elements and the left guide element and coupled to the second crank coupling location, wherein alternating motion of the right and left foot support members causes the first and second crank coupling locations to rotate.
