ABSTRACT:
A machine for exercising the rotator cuff of a user includes an upright support frame having a front, a top, first and second sides defining a plane of the upright support frame, and a support structure extending from the front adjacent the top of the upright support frame. The machine preferably includes a forearm support assembly for supporting a forearm of the user in a plane substantially transverse to the plane of the upright support frame, wherein the transverse plane also passes through the shoulders of the user such that the user's arm is positioned substantially in the transverse plane to isolate the user's rotator cuff. A tension mechanism is mounted on the upright support frame and includes a tensioned cable. A cam mechanism is connected to the tensioned cable and supported by the support structure of the upright support frame for rotation with the forearm support assembly under tension as the user's forearm is rotated.
