I find that on overhead press the most limiting factor is my lower back. my shoulds can push a shit load of wieght, but when that arch is over exerted, my strength goes to shit. Super setting with deads is really rough for this reason (ala waterbury hybrid).
But shit, it feels good when you stop so keep on with it hahahah
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
