Abstract: The disclosure describes a rotator cuff machine comprising an upright support frame having a front, a back and two sides. A handle is connected to a tensioning structure mounted on the upright support frame. The tensioning structure biases the handle such that the handle can be moved forwardly of the support frame under tension. A first body support member is spaced from the upright support frame and contains a first support surface positioned in front of the upright support frame. A second body support member is spaced from the upright support frame and contains a second support surface positioned in front of the upright support frame. The second support surface is spaced laterally of the first support surface and is also spaced vertically above the first support surface such that the arm of a user can rest substantially horizontally on the second body support surface while the user sits on the first body surface.
