He has to pull from a dead stop on every rep, and also to a complete lockout......nothing else will suffice.
No straps, no bouncing,no hitching,no bent knees in the top position, and he has to lean back flexing the erectors and cottage cheese glutes at the top of each rep.......old school style.
280 pounds is around 50 pounds under his bodyweight.............. ...pathetic that I`m even involved in this fiasco but whatever.........I pulled 300 pounds as a 130 pound child.
