How to perform 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. 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.

1. Chair Squat
95% match- Quads
- Machine
- Beginner
- Compound

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.
Hack Squat FAQ
What muscles does Hack Squat work?
The hack squat primarily targets the quadriceps, vastus lateralis, medialis, and rectus femoris, while the glutes and hamstrings act as secondary stabilizers. Keep feet shoulder-width and drive through the midfoot to emphasize quad recruitment and limit hip-dominant compensation.
Can I build muscle without doing Hack Squat?
Yes, you can build equal quad hypertrophy using front squats, narrow-stance back squats, leg presses, and progressive unilateral work, provided you apply progressive overload and sufficient volume. Emphasize controlled eccentrics, full ROM, and cues like 'knees tracking over toes' to ensure consistent quad activation.
