Watch 5-Star RB David Gabriel-Georges Is Deadlift 725 Pounds

2 Things:
1) That's not a dead lift, It's the concentric portion of a trap bar deadlift. 0 reps
2) 600 lbs is a lot of weight to rack and unrack, but calling that a squat is unfair to those that lift. 0 reps

I've seen bigger quads in the quad.
