Squat Form Check

Hi, I think i have some buttwink / lower back losing its arch at the bottom of my squat but no one in my gym can seem to confirm it, everyone i ask just says “it looks fine”. im not sure if you can tell by the video, the safety bar is blocking the view. anyways, i thought id give it a shot.

btw those arent wraps, they are those ATP sleeves that look kind of like wraps

thanks
