sometimes when i just did a heavy back or legs day i bump into shit. some people aren't doing it to be assholes. I just lose myself in my lift sometimes. i've never been that unaware of my surroundings though. a lot of guys go to the gym and see a big guy and try to lift what / how he's lifting. that type of shit that happened to you is one of the reasons i been lifting real light lately, doing a ton of reps / sets - noone looks twice cause your not throwing around a couple hundred lbs
