BODYWEIGHT SQUAT
1) When performing the squat, let your body weight shift back into your heels as you sit your hips back.
2) Keep your knees as far back behind your toes as possible.
3) Keep your chest up and back held in neutral position or with a slight arch.
4) Prevent yourself collapsing forward as you perform a squat.
5) Make sure your toes, knees, and hips are all in line as you squat back.
