I'm not an anatomy wiz so bear with me.
I want to say an elevated shoulder girdle is a more advanced issue than just an internal rotation/impingement issue.
I've had a lot of problems with shoulder balance and health because information wasn't specific enough to go beyond "balance your upper body from front to back with more pulling exercises" or "do more upper back work."
Common advice has been to "keep the elbows in to hit the lats," but most lifters aren't aware that the lats actually internally rotate the shoulders....
So movements like pulldowns, rows, straight arm pulldowns, chinups and pullups aren't ideal for shoulder health if the lats are the prime movers.
Obviously you can target the lower traps and rear delts by flaring your elbows, but that never seemed natural, at least not to me.
Consequently, movements like pull aparts, external rotations, and face pulls, which are very good for shoulder health, are almost non existent in gyms.
I've been meaning to make a thread screaming that upper back work means lower traps and rear delts and not lat work but I never got around to it.
