The trainers personality is very off the cuff and we have a pretty open friendship. He is in his late 50s and is married. He made a comment the other day about liking watching my ass move up and down during this workout. I believe he was kidding but maybe not. Do you think other guys notice my ass too? I'm 5'8 and weigh about 135 pounds but am super fit. I've gained muscle in my butt from doing squats etc.
