I need some help with my bench. When I bench, it really seems to irritate my shoulders. I can push press/military press/klokov press with absolutely no shoulder discomfort. I can bench with dumbbells with no shoulder discomfort. I say this to illustrate that I think my shoulders are healthy, but that it is something explicit about the bench with the barbell that messes me up.
I am guessing that I am shoulder dominant when I bench, but I am looking for tips on how to bench properly without messing up my shoulders permanently. The ache I get from benching lasts a full day after I do it, sometimes two.
