Here's a story that kind of sums up the mentality of serious trainers...I was training with a powerlifter who is ranked #1 in the province, he's 5'7" and over 285lbs. We were both going for maxes that day, he on the squat and me on the deads. Well, he hit a 785lbs like he was playing with it, and I pulled a 545lbs single with no belt (I was happy with that as I'm a bodybuilder, not a powerlifter). We were in the changeroom chatting afterwards comparing marks, my shins were bleeding openly and he had burst a shit load of blood vessels in his upper chest from all the weight he had squatted, and a bunch of young teenagers walked in. They took one look at the crazy fuckers comparing wounds and beat it back out.
Lift hard or go home...
