LOL it takes time.. you're supposed to use your whole body when you're doing the powerlifting technique. Though it doesn't target the chest as much as the flat bench you gain a lot more power in your back, forearms, and legs
I do mine flat bench but pinch my shoulders so i won't flare my elbows to prevent any future shoulder injuries and that targets my chest the most, and i don't want to go super heavy because not a lot of people workout when i go in the morning so spotters aren't really an option
who's going to catch that weight ?
