Reverse Shoulder Replacement Surgery - Is There a Weight Limit?

I'm 76 years old and recently stopped all upper body work due to pain. Prior to stopping, my best was a two 25 dead lift. I have three irreparable rotator cuff muscles. What exercises can i do, and is there a weight limit following reverse shoulder replacement surgery? It's just the frustration having your shoulderope, god them. And she was like 12 when she had that surgery. You know, you're 76 years old. Ahwiere's an lim here. That hurts real bad. If i was 76 and i had your situation, i wouldn't let these fuckers chop on my shoulder again.
