The exercise arm assembly includes equally spaced ports and locking pins to allow altering the active length of the arm. Further, the platen contains ports, radially positioned around its facial surface to permit adjusting the angular displacement of the exercise arm through 90.degree. either side of the horizontal. The platen also has inscribed degree indexes to define angular displacement from preset azimuth during the exercise routine.
