Confident, much?

This morning when I started my workout I was alternating between pull throughs and DB rows. There was a guy working out near me but I wasn't paying too much attention to him. He came over after I finished my last set of the group and asked me what the pull throughs were for. I said glutes. He said he'd never seen them done before and that he thought I was 'posing for him'. I just laughed. Jerk.
