A weight stack is provided and has a plurality of predetermined weight elements which are guidingly connected to a pivoting support platform. Restraining guide rods are secured to the pivoting support platform to permit the weight elements to be displaced therealong in a predetermined stack form. An elongated carrier rod extends freely through the weight stack and has a plurality of attachment holes along a prescribed length thereof. A connecting pin secures a selected one of the weight elements to one of the attachment holes of the carrier rod to form the predetermined stack. A pivotal connecting linkage is secured to the carrier rod and to a pivoting exercising frame engageable by a user person to perform an exercise. The predetermined stack is displaced along the restraining guide rods during a pivoting displacement of the pivoting exercising frame while the pivoting support platform and pivotal connecting linkage pivot whereby to accommodate an arcuate displacement of the rear end portion of the pivoting exercising frame when displaced about a pivotal connection.
