Last night was the first time I have ever seen anyone wear a squat suit at the LA Crapness. Now I know what you're thinking but stop right there. You do not need a squat suit, knee wraps and a belt...
Why don't you go and try it? Increase the weight until you hit the wall. Be warned though, don't think just because you can squat 300+ on a smithy that you can even do 225 on a barbell.
I negged him the minute he posted no. Then someone with 20k smacked his ass into the ground. He was way way way red yesterday for about 5 minutes before the thread vanished.
