Abstract
Abstract A exercise bench system has a lower bench that rests on the floor and carries on it a separate upper bench in any of three positions of interfit: (1) collapsed flat on the lower bench, (2) inclined relative to the lower bench, (3) upstanding parallel with the lower bench. The upper bench has detachably affixed to it, by stud and socket and flange hook, a leg extension-leg curl pivotal component that can be set for limited pivot if desired. Seat structures provide an incline position on the lower bench when horizontal, in cooperation with the pivotal component fixed to act as a post. The lower bench has transverse base members connecting the lower portions of the legs, and a pulley for guiding when a line is attached to the pivotal component and run back to any suitable weight stack.
