I was an idiot when I was younger. I worked for a bottled water company and let the full weight drop from over my head on my shoulder joint. We are talking about 48 pounds from 6 feet in the air with just a grip on the bottle neck. My right rotator cuff is shot. On inclines I feel like it may blow out of socket. I can't do militaries with any kind of weight without suffering for several days. What are some good substitutes that will not destroy my shoulder on chest and shoulder day.
