A multipurpose exercise apparatus for performing free weight bar bell exercises is disclosed. The machine includes a pair of weight frames, each of which includes spaced apart columns and spaced apart horizontal top beams supported by the columns. A weight support member is disposed vertically between the columns and includes a plurality of apertures, a stack of primary weights being supported on the weight support member by a pin which is specially adapted to carry one or more supplementary weights. A bar assembly for performing diverse barbell exercises is connected by a pair of cables to the weight stacks and includes a pair of spaced apart bar support members which provide limited universal joint action with a lifting bar. Optionally, the cables may have detachable couplings intermediate their lengths in order that the bar assembly may be disconnected from the weight stacks and individual hand grips then connected to the cable segments for performing diverse additional exercises.
