Few inches shallow (but not dreadful depth), knee wraps, mountains of gear, and a wrap-'round spot (don't underestimate this edge), but otherwise, better than I expected.
Having said this, I am 47 and can sink this weight ass-to-ankle with no drugs and no wraps, for several reps. All things considered, Levrone is only a symbol of the dramatic effects of hormones and pharmaceuticals. I'd expect if he was a genuine hardcore mofo he'd have never stopped and would be smashing sets of eight with considerably more.
Shit, he's on GRAMS of gear.
As others say, however, Kevin doesn't require such weight to derive maximal muscle-building benefit from free-bar squats. Multiple (deep) sets of 10-12 with 315-405 is sufficient.
The fact he's SO overperforming (and not a habitual heavy weight trainer) solely from heavy gas use puts him at extreme risk for injury.
Levrone is all ego and ignorance.
