I most definitely could do what Ben did in this particular video (which as said is past his prime). It is a complete shit squat and unimpressive. I know numerous athletes on this site alone who have squatted more weight deeper and with technique that is actually safe and beneficial. There isn’t a chance that the Ben in this video could do 455x1 to parallel without knee wraps and with a controlled eccentric. Absolutely no chance.
You just don’t have a clue about what you’re talking about and probably have no idea how to squat yourself. It isn’t even about it being a slight bit off technically as nobody is perfect with technique and a person not competing in the sport is rarely going to have optimal form, but the form in the video is so incredibly unsafe is poses an IMMEDIATE risk to the athlete, who could have a back injury at any time doing such a stupid technique.
