ABSTRACT:
A rear deltoid exercise machine includes a frame, a bench supported by the frame along a vertical midplane and two independently pivotal levers connected to the frame on opposite sides of the midplane adjacent a head end of the bench. Each lever includes a hub adapted to hold at least one removable weight, a connector that extends rearwardly toward the bench and an actuating pad at the rear end of the connector. With the backs of the upper arms engaging inwardly directed surfaces of the actuating pads, an exerciser lying face down on the bench may pivotally raise the levers upwardly, through shoulder adductive motion, against the weight supported on the hubs to exercise the rear deltoid muscle groups.
