I'll come right out and say it, I don't believe he can do it. Everyone acts like squatting 500 pounds is so pedestrian, I've maybe seen that happen 3 times in the gym. Jay Cutler never squats more then 405 (for reps, but still).
Then the defense is always "those numbers aren't even good, why are you questioning me?" Take all of this into account with the guys height and weight and I'm calling bullshit.
That being said, I don't care if he posts a video or not, I've come to take e-lifts with a grain of salt.
