Abstract
An exercise apparatus having foot beams (38a, 40a) rotatably mounted to an upright post member (140a) of a frame to rotate about a first axis (322). Hand levers (132a, 134a) are secured to pivot members (152a) pivotally mounted to the upright post member to rotate about a second axis (328). The hand levers are coupled by resilient linkage members (340) to the foot levers so that as each foot lever rotates about the first axis, the corresponding hand lever normally rotates a related distance about the second axis. The linkage members are resiliently deformable to allow discontinuity between the rotation of the foot levers and hand levers when an exerciser exerts a differential force on the hand levers relative to the corresponding foot levers.
