Abstract

A power body building machine for athletes, gymnasts, body builders and the like for exercising the upper torso, including the chest, the back, and the shoulders. A rigid, upright, free standing frame includes a pair of rigid, spaced apart, sides which dynamically mount a weight bar assembly which extends horizontally therebetween. A user may enter the machine through the frame and grasp the loaded weight bar assembly, which may be stressed with "outboard" free weight bar assembly is slidably coupled to parallel, rigid, guide rods associated with each of the frame sides rods which establish a vertical travel path and it is manipulated by handles which are slidably mounted upon it for horizontal movement, and which are synchronized with each other by a cable assembly. A user can exercise by concurrently performing hand/arm movements and hand/wrist rotation while the stressed weight bar is manipulated. Rotatable sprockets are associated with the top and bottom of the machine frame. A chain entrained about the upper and lower sprockets synchronizes the weight bar assembly and enables it to be stressed when moved either upwardly or downwardly. The upper sprockets are synchronized by a rod extending across the top of the frame between them, so that proper control of the weight bar assembly is facilitated.
