Maybe I just seem completely unapproachable at the gym. I don't storm around the place or scowl at everyone, I only bring headphones about half the time, I don't throw shit around or scream.
I do wonder how I would react if someone said something about my squat, which is by far the weakest of the main lifts for me (245lb ass-to-grass front squat with a clean-grip as opposed to a 475lb deadlift with no straps or belt. WTF?!?!?!?). I think I would just look at them for a second and then go back to what I was doing because, really, the opinion of someone stupid enough to question what I'm doing when they know nothing about my goals or my past lifting history doesn't warrant any attention from me. I mean, this is a gym where I am literally the ONLY PERSON who I have ever seen foam roll any part of their body, ever.
But no one's ever going to say anything about my weak-ass squat because I have never seen most of the people in there who are about the same size as me but bench more do ANY sort of lower-body work aside from a random set or two on the leg press with a few plates on either side.
