ON box squats, should one actully sit down like that or is your ass just suppose to touch it and use explosive power to drive upward? thanks for the clerification
You stop momentum, but you don't sit down and relax. You MUST stay tight.
WRT the JM presses, they are awesome for chaos recovery. On my 240 attempt at the comp, I was SO GRATEFUL that I had been doing these religiously. The bench was slick, I got out of the groove, and my right arm benched while my left arm did a JM press. It pays off.
