Six months ago I had surgery to reattach my left bicep. It completely detached from the bottom insertion. My arm looks ridiculous, but that is the least of my worries. I need to rehab it. Surgeon said I am good for working out. Anybody have experience with type of injury. The last 20 years have been spent mainly powerlifting, compound movements etc. Never had to rehab myself. My main concern is not doing this all over again. I do not recommend this injury for anybody.
