Barbell Hack Squat

Description

The barbell hack squat is an old-school standing quad exercise where the barbell is held behind the body with arms straight, starting on the floor behind your heels. Named after George Hackenschmidt, the wrestler who popularized it, the lift loads the quads heavily through a unique posterior-loaded squat pattern. It is more knee-dominant than a traditional deadlift and more posterior-loaded than a squat.

Barbell Hack Squat Instructions

Stand in front of a loaded barbell so the bar is on the floor directly behind your heels.
Squat down and grip the bar with an overhand grip, hands roughly shoulder-width apart, palms facing your body.
Set your feet shoulder-width apart with toes slightly turned out. Lift your chest and brace your core.
Drive through your feet and stand straight up, lifting the bar off the floor while keeping it in contact with your glutes and hamstrings on the way up.
Stand tall at the top with the bar held behind your thighs and arms straight.
Lower the bar by sitting back and bending the knees, keeping the bar tracking close to your body.
Touch the bar lightly to the floor (or stop just above) and drive back up for the next rep.
The lift is unusual and feels awkward at first — start light and master the groove before loading heavily.
