Abstract
An exercise apparatus having right and left foot pedals with a forward end thereof pivotally supported by right and left swing arms and a rearward end thereof pivotally supported by right and left lift arms. In an alternative embodiment, a lift cable is used. A swing control member interconnects the swing arms to provide a dependent action with the rearward movement of one pedal causing the forward movement of the other, and an interconnect member interconnects the rearward end portions of the pedals to provide a dependent action with the downward movement of the rearward end of one pedal causing the rearward end of the other pedal to move upward. The swing control member and the interconnect member are operatively disconnected such that while the forward and rearward movement of the right and left pedals have dependent action and the downward and upward movement of the right and left pedals have dependent action, the forward and rearward movements and the downward and upward movements are independent of each other. A resistance device resists rearward movement of the right and left pedals.
