How to Perform Narrow Stance Hack Squats

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 less than shoulder width narrow stance with the toes slightly pointed out. Your feet should be around 3 inches or less apart. 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.
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.
6. Begin to raise the unit as you exhale by pushing the floor with mainly with the heels of your feet as you straighten the legs again and go back to the starting position.
7. Repeat for the recommended amount of repetitions.

1. Narrow Stance Leg Press

92% Match

Quadriceps Machine Intermediate Isolation

How to perform this exercise

1. Using a leg press machine, sit down on the machine and place your legs on the platform directly in front of you at a less-than-shoulder-width narrow stance with the toes slightly pointed out. Your feet should be around 3 inches or less apart. Tip: Keep your head up at all times and also maintain the back on the pad at all times.
2. Lower the safety bars holding the weighted platform in place and press the platform all the way up until your legs are fully extended in front of you. Tip: Make sure that you do not lock your knees. Your torso and the legs should make a perfect 90-degree angle. This will be your starting position.
3. As you inhale, slowly lower the platform until your upper and lower legs make a 90-degree angle.
4. Pushing mainly with the heels of your feet and using the quadriceps go back to the starting position as you exhale.
5. Repeat for the recommended amount of repetitions and ensure to lock the safety pins properly once you are done. You do not want that platform falling on you fully loaded.

2. Lying Machine Squat

91.4% Match

Quadriceps Machine Beginner Isolation

How to perform this exercise

1. Adjust the leg machine to a height that will allow you to get inside it with your knees bent and the thighs slightly below parallel.
2. Once you select the weight, position yourself inside the machine face up with the knees bent and thighs slightly below parallel to the platform. Make sure that the knees do not go past the toes. The angle created between the hamstrings and the calves should be one that is slightly less than 90 degrees (since your starting position requires you to start slightly below parallel). Your back and your head should be resting on the machine while your shoulders are pressed under the shoulder pads.
3. Place your hands by the handles and position your feet slightly pointing out at a shoulder width position. This will be your starting position.
4. While pressing with the balls of the feet as you breathe out, make your whole body erect as you squeeze the quads. Hold the contracted position for a second. Tip: Since you are starting below parallel, you can opt to use your hands to help you up by pressing on your thighs only on the first repetition.
5. Slowly squat down as you inhale but instead of going all the way down to the starting position, just stop once your thighs are parallel to the platform. The angle between your hamstrings and calves should be a 90-degree angle.

3. Smith Machine Leg Press

90.1% Match

Quadriceps Machine Beginner Isolation

How to perform this exercise

1. Position a Smith machine bar a couple feet off of the ground. Ensure that it is resting on the safeties. After loading the bar to an appropriate weight, lie underneath the bar. Place the middle of your feet on the bar, tucking your knees to your chest. This will be your starting position.
2. Begin the movement by driving through your feet to move the bar upward, extending the hips and knees. Do not lock out your knees.
3. At the top of the motion, pause briefly before returning to the starting position.

4. Smith Sumo Squat

85% Match

Glutes Smith-machine Intermediate Isolation

How to perform this exercise

1. Set up the smith machine with the barbell at hip height.
2. Stand with your feet wider than shoulder-width apart, toes pointing outwards.
3. Position yourself under the barbell, resting it on your upper back and shoulders.
4. Engage your core and keep your chest up as you lower your body down into a squat position, pushing your hips back and bending your knees.
5. Lower yourself until your thighs are parallel to the ground, or as low as you can comfortably go.

5. Hack Squat

84.4% Match

Quads Machine Intermediate Isolation

How to perform this exercise

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.

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 discussed in the foot stances section.
3. Begin to slowly lower your torso by bending the knees as you maintain a straight posture with the head up. Continue down until you slightly touch the bench behind you. 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.

9. Wide Stance Barbell Squat

82% Match

Quadriceps Barbell Intermediate Isolation

How to perform this exercise

1. This exercise is best performed inside a squat rack for safety purposes. To begin, first set the bar on a rack that best matches your height. Once the correct height is chosen and the bar is loaded, step under the bar and place the back of your shoulders (slightly below the neck) across it.
2. Hold on to the bar using both arms at each side and lift it off the rack by first pushing with your legs and at the same time straightening your torso.
3. Step away from the rack and position your legs using a wider-than-shoulder-width stance with the toes slightly pointed out. Keep your head up at all times as looking down will get you off balance, and also maintain a straight back. This will be your starting position.
4. Begin to slowly lower the bar by bending the knees as you maintain a straight posture with the head up. 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).

Why You Might Need a Narrow Stance Hack Squats Alternative

You might substitute narrow stance hack squats because the machine isn’t available, you have knee pain with the hack pattern, or you want more transferable strength. Alternatives let you change joint angles and muscle emphasis; for example, a front squat shifts some load to the hip extensors when you lean forward, whereas a narrow leg press increases knee flexion and quad activation. Modify technique to protect joints: reduce range of motion if symptoms appear, keep knees tracking over toes, and pause at 90 degrees to reduce shear. Choose movements that reproduce the quad-dominant knee-extension pattern without aggravating existing issues.

How to Choose the Right Substitute

Select a substitute based on equipment, goals, and biomechanics. If you have a barbell and want maximal overload, use the front squat with an upright torso and knees forward to target the quads; cue elbows high and knees over toes. For machine access, use a narrow-footed leg press and place feet low to the platform to increase knee travel and quad recruitment. If correcting imbalances, choose Bulgarian split squats and drive through the front heel to load the quad unilaterally. Prioritize exercises that reproduce the hack-squat’s knee-dominant pattern and allow progressive loading while keeping safe joint mechanics.
