You can't be serious with this statement.....you should take a second (with all due respect) to learn the differnce between a type-1 and type-2 AC joint. Look at the research of pressing movements combined with each type of joint. For example, for someone with a type-2 AC, BTN presses are an absolutely NO NO...the impingement that occurs will absolutely lead to a rotator strain/tear/etc etc
yeah i know but, you are talking about genetic structure of the shoulder and not a whole lot can be done with that except surgery. most people are still going to press regardless and, pressing puts a significant strain on the RC, and it's usually the only thing that bottlenecks me when lifting. my pecs and shoulders will recover a lot faster than my RC because i'm hitting my RC multiple times a week, so i wouldn't add anymore RC exercises a week.
i'm pretty sure i'm a type 2 or 3, since my shoulders are always impinged and hurt. i think i inherited it from my dad as he had the same issue and had his long bicep tendon severed due to impingement even though he doesn't lift.
