been doing them daily for like 8 weeks and my squat depth improved without me trying to force it. i thought my depth issue was ankle mobility for years, turned out it was mostly hips locked up from sitting 40 hours a week. if u have never done 90/90s just sit on the floor with one leg bent in front and one bent behind, both knees at 90 degrees, and slowly rotate side to side. sounds simple but ur hips will let u know real quick where ur restricted.
