Personally I always like wearing minimums running shoes when I do squats and dead lifts. There's little to nothing to the shoes so its as if your lifting bare foot, without actually taking your shoes off. I also wear light weight shorts, generally Adidas they are super comfortable. I do wear wrist wraps for the added support with heavier weights; I never wear gloves (Build thoes calluses!) For shirts I'm always rocking the SHF cut offs, the freedom and the fact that they breath so well is very important to me.
What do you all wear in the gym?!
