People are talking about how maybe it's because he likes to hear the plates jiggle or that it's easier to take the weights off at an angle when doing hack squats. The thing is in the video when he's doing leg press on the machine he doesn't separate the plates whatsoever. But for some reason, when doing hack squats on the machine, he does.
Maybe it is an OCD thing for him. Who the hell knows. And no, I did not loose sleep over this.
