shoulder scope

i will be recieving arthroscopy shoulder surgery to remove bone spurs in the AC joint
they are talkin 2-3 days in a sling, and then 2 months before heavy lifting (bench, military, cleans, etc)
what can i do to keep in shape/reduce atrophy during this time?
what about max contraction?

Your rehab will most likely consist of high volume work. When I had reconstructive shoulder surgery my rehab consisted of lifting 3x a day. The excess volume will be probably be a nice change of pace. Who knows, you might even see some growth. The main thing is to work hard at the exercises you are given. Be smart, your shoulder will tell you what you can and can’t do. Best of luck.
