Barbell Hack Squat

How to do it

Stand with the barbell on the floor behind your heels and grip it with both hands behind your body, palms facing back.
Set your feet about hip width apart and brace your core before lifting the bar off the floor.
Bend your knees and push your hips back to squat down, keeping the bar close to your calves as it travels behind you.
Lower until your thighs are near parallel, feeling the work concentrated through your quadriceps and glutes.
Drive through your heels to stand back up, exhaling as you extend your hips and knees to lockout.
Avoid letting the bar drift away from your legs, which shifts stress off the target muscles and rounds your lower back.
