Stand with feet shoulder-width apart and place a barbell across your upper back. Brace your core and keep your chest up. Begin lowering your body by bending your knees and hips, pushing your hips back as if sitting into a chair. Descend until your thighs are parallel to the ground or slightly below while keeping your knees aligned with your toes. Push through your heels to stand back up, extending your hips and knees in a controlled motion. Keep your spine neutral and avoid letting your knees cave inward.
