Context: 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 ! "

Question: Why did he tell you guys to suck in your guts and so on ?
Options:
0. He thought that we were better looking when we sucked in our guts and made our butts seem tighter
1. he liked to watch us while we worked out and he preferred that we looked slim and muscular
2. He wanted us to maintain the proper posture for the exercise that we were taking on and doing
3. None of the above choices .
Answer: 2
