premise: Last time he was leading us , I also noticed that his entire body ( arms , legs ) was totally smooth and hairless . So I am assuming he shaves his body as well . Also the last time he lead our class , we were doing exercises that caused him to yell , " Suck in your guts ! Squeeze your butts closed ! " Why did he tell you guys to suck in your guts and so on ?
hypothesis: He thought that we were better looking when we sucked in our guts and made our butts seem tighter
