Abstract
An exercise bar for use with standard weight machines employing exercise bars. The bar is vertically hinged in the center, so that it is usable not only for pull down exercises, but also forms a vee which is compressed during pectoral exercises. The two sides of the vee are geared together, so that the vee opens and closes symmetrically, both arms being forced to move the same amount. An adjustable spring assembly attaches to the bar for selectively varying resistance for the pectoral exercises. A brace contacts the user'"'"'s forearm, so that the user applies a force countering the tendency of the bar to incline responsive to being drawn downwardly. The bar is configured to include a relief in the center, so that it can be pulled down past the user'"'"'s head, while avoiding interference with the user'"'"'s neck. The novel exercise bar is rugged, uncomplicated, increases the number of exercises which can be performed, and can be retrofit to a standard weight machine.
