Added 2022-07-22 02:35:06 +0000 UTCProof as to why you should train both sides. :( my right rotator cuff is idk what's going on with it, it's just much weaker because I've always pushed with my left shoulder, and pulled with my right. This exercise isolates the rotator cuff like no other I've felt. I could barely do it on my weak arm.
