Description

Hack squat focuses on controlled movement and maintaining proper body alignment throughout the exercise. The goal is to create tension where needed while avoiding unnecessary strain or momentum. This helps improve movement quality, joint stability, and overall physical control.

Instructions:

  1. Place the back of your torso against the back pad of the machine and hook your shoulders under the shoulder pads provided.
  2. 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.
  3. 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).
  4. 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).
  5. 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. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that is perpendicular to the front. If your knees are past that imaginary line (if they are past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly.
  6. 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.
  7. Repeat for the recommended amount of repetitions.

Exercise FAQ

What’s a common mistake people make here?

Rushing reps and losing body position. Keep the movement smooth and repeatable so tension stays where you want it.

What should I focus on to keep good form?

Move with control and keep your torso stable. Use a range of motion you can own, and stop the set if you need momentum to finish reps. Think of it as squat pattern done with repeatable, clean reps.

What should I do if I feel it in the wrong place?

Check your setup, slow down, and reduce weight. If discomfort is sharp or in a joint, stop and choose an easier variation. Think of it as squat pattern done with repeatable, clean reps.
