I think the vid proves the kid and his pops are full of shit, use improper form and can't squat worth a shit. the kid had some good thighs but only compared to his weak upperbody. I never squatted ass deep. My ankles don't allow me to go down that deep without raising my heels off the ground. I did it to parallel and could get up to 500-515 but with a spotter acting like a weightlifting suit on me.
I'd never brag about how much weight i lifted but i could sure as hell do 225x20 with no problem - even today with my knees completely gone to shit. I tried high rep squatting after that pic of Tom Platz on Ironman and the article in it. All i'd get is exhuasted and a good pump, but no size to speak off. ]
Great ownage either way though.
