This was a few years back but might help your thought process. I've shot archery my whole life and feel like I have taken decent care of myself. Do some weights, peloton, hike and shoot a lot. I had horrible bone spurs in my left shoulder that basically destroyed my bursa. Couldn't tie my shoes, button or unzip pants, shirts on over my head etc. Went to lots of PT which did zero, but Insurance said I had to before they'd let me have surgery. I finally had surgery in Feb of '12, they went in a ground down 5/8" from one bone and 3/4" from the other and worked on the Bursa. I did exactly the rehab that the Dr said to the T. There were days that I wanted to do more but didn't, I think this is where people get themselves into trouble. At 4 months post operation, I started pulling bands back like a bow, I also ordered 25# limbs for one of my bows and started shooting it shortly after that. I made it to 62# by Sept 1 and killed a buck and bull that year. That was 12 years ago and my left shoulder is better than my right for sure. It does work, but PT and following directions is a must do. The surgeon did say that because of my regular conditioning routine with weights before my injury, did help with the recovery. PM me if you want more info....wish you the best
