My coracoid process is blocked from moving properly – and yes, I did smashing and mobilizing for months until we figured out the problem. I had a broken humerus and collar bone at 13 that wasn’t treated properly and then I was sedentary for the next (mumble, mumble) decades. Consequences from the improperly treated shoulder has led to a mechanical problem that has really effected my external rotation. Thankfully that shoulder is VERY stable, so deadlifting and related lifts aren’t a problem. The problem comes when I want to do something at shoulder height or higher.
