i didnt see ur video, but is that all ur chest routine consisted of??? 2 full reps, and a try at 2 maxes??? that wont do much in terms of building muscle or strength--stay away from the maxes for a month--stay around 6-8 reps on say like 225, and go for ur max in like a month--i wouldnt wana see u go down cuz ur not stimulating ur chest muscles enough, or worse get hurt maxing---good luck bro
