Yes, I have a group of them at my gym. They're all big and juiced up but with no legs, a little tubby and they travel in a pack. They look at me but don't want to acknowledge the fact that I'm in decent shape because I'm not a part of their tubby pack. I was working incline bench and going heavy and when I finished my set and sat up quickly. It was like turning on the lights and watching roaches run to hide. One dude was peeping around the corner behind a pillar. Another one was behind a stair master and the other 2 were kneeling down watching me but were watching the reflection bouncing off of two mirrors. They turned around to pretend they were not watching all at the same time. I couldn't help it. I sat on my bench and laughed for a few minutes. Sometimes when I walk by I see them look at me then look in the mirror at themselves and they say stuff like "we should start doing cardio!"
I don't know what it is. I think I'm to worried about my own body dsymorphia but I NEVER EVER compare myself to other guys at the gym. You will never see me look at someone bigger and in better shape than me then look down at myself comparing. I just give a nod "nice work!" and keep walking.
