Patent attributes
A portable exercise machine is provided for rotator cuff exercise. The portable exercise machine includes a flat board having an upper surface and a U-shaped cutout for receiving a torso of a user. A pair of opposing, rotatable arms are affixed to the upper surface of the flat board. The distal end of each arm includes a handle adapted to be grasped by a user and the proximal end of each arm is pivotally coupled to a steel coil. The steel coil provides resistance against the rotation of the distal end of the arms. The steel coil can be removably affixed to an inner connection region or an outer connection region of the flat board. The outer connection region provides resistance for inward movement of the arms and the inner connection region provides resistance for outward movement of the arms.
