DB and BB shrugs are my best friend. so today, i figured, since i do OH squats, i might as well do OH shrugs i was in for quite a surprise i tried it first with DBs my left side was fine, perfect ROM, i could elevate and descend normally but my right side...get this: i couldn't even "reach" or extend my arm. its as if it wouldn't move or i had no muscle/nerve endings/whateverthefuck there whatsoever. what the hell is going on? is it a muscle imbalance? weakness? flexibility issue?
