Maybe your form was wrong? Hey, it’s possible!
Yea , hes a jack ass, i get it all the time just look at him and keep doing what your doing. Your not a wuss , you got to start some where. I know alot of people who cant do that much.
As for form just make sure you have a little bend in the nees, sit back with your ass,bend over with the hips, and keep bar in front of your nees. ITs agreat exercise thats hard and not very many people do so he proble thought you were trying to do a squat or he is an ass who runs on the bike all day and then takes his stack of super duper gnc crap.
