I also had rotator cuff surgery :-(. As Susan said: no fun. In addition to the PT guidelines, here is what I do not do:
Upright rows and lateral raises straight out to the side. I still do rotator cuff exercises even though my surgery was a long time ago. I am careful about the load of upper body exercises. I do overhead presses but with rather light weight; they do’t bother me but I am always cautious.
Since I am a MELT instructor, I do all the MELT length and strength movements for the upper body and found those very helpful.
