How to Perform Hack Squat

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.

Why You Might Need a Hack Squat Alternative

You might replace the hack squat because the machine isn’t available, you feel anterior knee pain, or you want unilateral work to fix imbalances. The hack squat is a knee-dominant compound that emphasizes knee extension over hip extension; substitutions let you shift load distribution and reduce joint shear. For example, front squats force a more upright torso and increase core demand while maintaining quad bias. Use cues such as 'keep weight on the midfoot, knees tracking outward' and adjust foot height—lower foot placement increases distal quad (vastus medialis) activation—so you maintain the target muscle engagement while changing the movement pattern.

How to Choose the Right Substitute

Choose a substitute by weighing equipment, pain history, and your training goal. If you want maximal quad loading in a commercial gym, pick a narrow-stance leg press or front squat and cue 'torso upright, knees over toes' to keep knee extension dominant. If knees hurt, select unilateral options like Bulgarian split squats to lower compressive forces and improve hip stability; drive through the midfoot to balance quad and glute activation. For hypertrophy use higher reps and controlled eccentrics; for strength use heavier loads and lower reps. Test foot position and tempo to find the movement that reproduces the quad activation you need.
