But how ? Because he does have mass in his quads, but nothing compared to powerlifters.
Years of power training in weightlifting where the goal is to lift more on C&J and snatch. That squat is an accessory exercise!!!
You have to bear in mind that he is doing a 3xBW squat there at ~200lbs, so considering the guys weighing 20-30kg heavier at the same level (i.e. world class) in power lifting are squatting ~1000lb to parallel and in gear then it is about right.
