You're going deep but your form is not optimal.
"Work on arching and sitting back with your hips more"<<<
"Zero hip extension, both on the start of the eccentric and tail end of the concentric. And this is no small thing. It's a foundational part of a sound squat, and tells us you probably need to go back to square 1."
and that definitely
Basically in beginning you are just going down you are not pushing your hips back
and sticking your but out which is the FIRST thing you should do due to having that
kind of form it looks like starting from rep 4 you are doing a partial squat/partial
good morning to get the weight up. Also it looks like your heels are coming off the floor
on reps 3,7 and 8.
As far as your knees coming over your toes when you go that deep at a stance that wide
that is going to happen.
I haven't really said anything that anyone else hasn't already said.
