ABSTRACT:
A rotary cuff exercise machine includes a frame, an elongated platform aligned along a vertical midplane through the frame, and two sides rotatably connected to the frame on opposite sides of the midplane. Each rotatable side includes a horizontally pivotal lever, a hub for holding removable weights on one end of the lever, at least one actuating pad connected to the lever away from the hub for pivotally moving the weighted lever and an elbow rest located below the actuating pad for supporting the elbow during pivotal movement. With elbows supported on the elbow rests, and the hands bearing against the actuating pads, an exerciser lying face up on the platform may pivotally move the weighted levers, through either an internal rotation or an external rotation, depending upon the direction the exerciser is pointed, to exercise the muscles associated with the rotary cuff joint.
