Im new to training just passed my year 1 mark. Recently I pulled a new PR 405 and I had ask this big guy at the gym to watch my form. I had never seen him Dl before but he gave my feind some good dl pointers and he was pretty big and lean so i figured he might no a thing or to. Normally when i dead i try to feel my belly with air and hold it until i lock the weight out.
He said my form looked good except that i shouldnt hold my breath the whole time or i could pass out, he referenced a you tube video. I watched it and the guy did indeed pass out after holding jhis breath for the duration of the lift. However i have seen many people who deadlift who hold there breath but dont pass out.
So my question is should i breath thru out the lift or just at lock out? Will breathing thr out the lift cause me to loose some of the tightness in my abbs? Is it just a personal preference thing?
