man i don't know about you guys but when i first started working out i learned two very imp things. always re rack your weights and never stand or walk in front of someone doin a set. for good reason it breaks there concentration. i don't ever see that anymore. including today. i'm doin military press drop set and on my last couple of balls to the wall reps and some smuck comes and stands right in front of me and starts doin shrugs with 30lb dumbells all wrong and at like 100mph. man did that piss me off. but just when i was gonna say something this guy next to me who was about 50 years old and in pretty damn good shape starts chewin this kid a new asshole. about how not to do that shit and really yellin at him. i just sat there and lmao. sorry for the long post just wanted to vent.
