Plus, check out the touch-point. The bar's perhaps two inches above his belly button. Such a severe low touch-point is only possible with the blast shirts. To attempt this raw is suicide. Also, it appears he's wearing two shirts. Whether the bottom one is another blast garment, who knows.
Without exaggeration, without the shirt(s), I'd suggest, with a controlled rep brought to his pec line or slightly lower, this guy would falter with much less than 500 pounds.
