I once had to pull 365 lbs off a guy who was benching in his jeans. he actually did a couple of reps w the weight . . . and then just got stuck.
i jammed and cut one of my fingers pretty deep as I helped him rack it . . . i had to come in from the front.
he didn't thank me either. I walked away. But i think if someone just saved my ass from asphyxiation, I'd find him and thank him. guy was a dumb shit.
i also saw a guy fail w 260 . . . funny thing was the weight didn't touch his chest. he lowered the weight to practically his knees in one smooth motion and then stood up w it. i was quite impressed.
