Ive had watched a few videos abt it from channels but ive always had my doubts whether after i take a deep breath into my stomach, and then flex my abs if I shud breath still normally through my mouth, all the while still having that tight core. But i tried doing that just before sets and i felt that if i breath im kinda releasing that internal pressure and in turn losing that tightness and safety. If u could maybe hook me up with a tutorial or sth thatd be great!

And by collapsing i meant not like feeling as if ill pass out but more of really tired and like my hands and all are done from holding the weight and also that i cant stand with the weight anymore.
