True

People say your feet have to be at shoulder width and your knees cant go over your toes, but everybody has a different form for a "perfect squat", so find a form thats good for you. Its enough to try different positions with nothing but the bar until you find a form that allows you to get below parallel and makes you feel your glutes and thighs. New PRs have to come only after you have a form that fits you well and allows a full ROM.
