Bent over rows...90 degrees, it's in the program as a back exercise, actually it's not in Starr's program, I think it is a modification Madcow made because without some coaching a lot of people butcher the power clean. Most people also butcher the bent over row to the point of making it a glorified jump shrug, thus totally ineffective at training the lats......read through Madcow's website and try to stay at 90 degrees.
