Barbell back squat

How to do it

1. Rest the bar across your upper back and grip it just outside your shoulders.
2. Stand with your feet shoulder-width apart and brace your core.
3. Sit your hips back and down until your thighs are about parallel to the floor.
4. Drive through your whole foot to stand back up tall.

Form tips

• Keep your chest up and your knees tracking over your toes.
