Since that book was written, I have had surgery on both shoulders. I used chin-ups and presses as the only rehab exercises I performed. I did NOT ONE SINGLE REP of any PT-type isolation movement for the shoulder. I am about 9 months post-op on the second surgery and I pressed 200 lbs. Monday night. Chin-ups help because they strengthen the whole shoulder under tension, so that the cuff is not impinged during the exercise. In fact, I was doing chins about 4 weeks post-op from the first surgery, a cuff tear repair. The second shoulder was an osteophyte removal/modified Mumford repair with no soft-tissue involvement, so it was much easier.
