If you don't already do them, I highly recommend rotator exercises. I do 6 sets twice a week, high rep, low weight. I kid you not, they have changed my life as far as lifting goes. Not long ago I could do no overhead presses, or incline bench. I now do them virtually pain free. IMO they should be done whether your having pain or not. Wish I knew about them 20 yrs ago lol.
