Abstract
An exercise apparatus (10) includes a frame (12) on which left and right levers (14) and (16) are pivotally mounted. A resistance mechanism (18) resists pivoting of the levers between nominal and displaced positions. The levers are coupled by a linkage (20), including an elongate coil spring (22) and an internal extension-limiting cable (24). The linkage normally acts to urge each of the first and second levers toward its respective nominal position when the other of the first and second levers is in a displaced position. The coil spring is capable of elongating to permit limited non-synchronous motion of the left and right levers, with the elongation of the coil spring being limited by the presence of the extension-limiting cable.
