Looking at the StrongLifts channel, I'm going to guess that the video of a 180kg/400lbs squat he posted a month ago is the first time he's managed that. Apparently he weighs around 170lbs/75kg. He never says directly. He also has consistent problems with lifting his heels and maintaining his back angle. Also too much yelling. You're letting all your air out fer' chrissakes.
Apparently he has been squatting for 13 years now.
