Hack Squat
Learn how to do hack squat with a clear setup, controlled movement, and a technique you can repeat.

How to do hack squat
- Place the back of your torso against the back pad of the machine and hook your shoulders under the shoulder pads provided.
- Position your legs in the platform using a shoulder width medium stance with the toes slightly pointed out. Tip: Keep your head up at all times and also maintain the back on the pad at all times.
- Place your arms on the side handles of the machine and disengage the safety bars (which on most designs is done by moving the side handles from a facing front position to a diagonal position).
- Now straighten your legs without locking the knees. This will be your starting position. (Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances described in the foot positioning section).
- Begin to slowly lower the unit by bending the knees as you maintain a straight posture with the head up (back on the pad at all times). Continue down until the angle between the upper leg and the calves becomes slightly less than 90-degrees (which is the point in which the upper legs are below parallel to the floor). Inhale as you perform this portion of the movement. Keep the feet planted and let the knees follow the toes through a range you control.
- Begin to raise the unit as you exhale by pushing the floor with mainly with the heel of your foot as you straighten the legs again and go back to the starting position.
- Repeat for the recommended amount of repetitions.

Start with a version you can control. Record the same setup and range each time. Add reps or a small load increase when you can repeat the movement without changing the technique.
