ABSTRACT:
An improved exercising apparatus specifically designed to permit, in a single compact unit, barbell type, lifting exercises as well as pull type, muscle toning exercises. Incrementally selectable, vertically movable weights are raised and lowered either by the exertion of vertical straight line forces on a vertically adjustable body engaging means removably connected to a vertically movable carriage which is directly coupled with the weights, or alternatively by the exertion of pull type forces on a second body engaging means coupled with the weights through a system of pulleys which reduces the amount of force required to raise the weights by a predetermined amount.
