ABSTRACT:
The force resistance device of the present invention enables the muscle groups which rotate the humerus about its axis to be safely and adequately developed. A base provides a series of rollers in a radial configuration which enables the humerus to rotate about its own axis. The device protectingly surrounds the elbow and lies adjacent the radius and ulna portions of the arm. Tension cords which may be selected based upon number and individual tension characteristics extend from an elongate portion to the base portion and about the curved portion which protects the elbow.
