Barbell Box Squat

Instructions

1. Set the barbell in a rack at upper-chest height and position a box behind you, a few inches from your heels.
2. Step under the bar, rest it across your upper back, and unrack it, then take a couple of steps back.
3. Inhale, brace your core, and descend by sitting your hips back until your buttocks lightly touch the box.
4. Pause briefly without relaxing onto the box.
5. Exhale and drive through your heels to stand back up to the starting position.
