48 and have partial rotator cuff tear on one side for 6-8 years or so. Was advised don't operate and do operate by two different surgeons. 6 months recovery put me off (I was told there is a good chance they have to bore the bone, bone spur removal or something?). I noticed it's getting worse with lack of consistent exercise. To get back to status quo I hit the gym and use small free weights (12-15 lbs) to strengthen deltoids.
