The Hack Squat primarily works the quadriceps, with the calves, glutes and hamstrings supporting the movement. It is a strength movement performed with machine.

Movement instructions
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. 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.
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.
Technique guidance

General guidance based on the exercise and equipment. It is not personal coaching or medical advice.
Your progress
Keep the same machine setup, range of motion and recording method when comparing Hack Squat sessions.
Weight, repetitions and completed sets.
Example: 3 sets of 8 reps at 30 kg. Next time, record the actual result, even if it is the same.
Look for more repetitions at the same weight, or a heavier weight for comparable repetitions. Total weight lifted also changes when you add sets, so it is not a strength score.
