How to Hack Squat: Variations, Proper Form, Techniques, Hack Squat Equipment

The hack squat is a dynamic strength exercise where the individual places their feet into position, leans back into the pads on a barbell at an angle and lowers to a 90-degree angle with the legs. It uses weight loaded on the shoulders to perform this move. 

Because the athlete is leaning back into the bar, with the torso immobile, it makes many lower body muscle groups work together, creating an effective compound lift exercise. 

Performing this movement helps build those mirror muscles in the legs that many athletes want to achieve. However, these muscle groups need isolation exercises to build power and strength. 

When performing the hack squat, multiple muscles are necessary. Although any squatting routine will activate these muscles, hack squats can isolate them more effectively since you cannot rely on the upper body during the movement. 

  1. Quadriceps
  2. Hamstrings 
  3. Gluteus 
  4. Calves 
  5. Hip flexors 
  6. Abdominals 
  7. Erector spinae 

Proper form is critical to avoid injury because the weight is on the shoulders and the athlete is on an angle. Foot placement, the depth of the squat, and the total weight are part of correct hack squat techniques to prevent getting hurt in the gym. 

Several injuries can result when mistakes happen during the execution of a hack squat. One common injury is from incorrect foot placement, or raising the heels during the lift can put excessive stress on the knees. 

Another significant problem athletes may experience include back pain after performing this movement incorrectly with hack squat equipment. Whether the load is too heavy or your form is not correct, any time there is lower back pain, you should reevaluate your circumstances before proceeding.

How To Perform a Hack Squat With Proper Form

It is simple to perform hack squats when you follow the proper techniques. 

  1. The feet should be ahead of the knees and wider than shoulder-width. This positioning will keep unnecessary stress from the knees. 
  2. Shoulders should be resting comfortably on the padding. Proper placement will help to avoid back injury. 
  3. Slowly begin to descend until the legs form a 90-degree angle with the floor or close to parallel. Do not use quick movements or risk straining or injuring the muscle groups. 
  4. Press into the heels of the feet to extend back up to the standing position. Avoid lifting the heels since it will create knee stress and pain. 
  5. Always warm up with a lighter 40 to 50% of your maximum target weight. 

What Are the Benefits Of Doing a Hack Squat?

Several benefits can help sway your decision if you want to consider adding the hack squat machine to your workout routine.

  3. It Will Help You Lift More 
  4. Makes Your Knees Stronger
  5. Lowers the Risk Of a Lower Back Injury

1. Your Quads Will Be Developed

Because the hips are stationary, the hack squat muscles worked during this exercise receive more intensity, encouraging the building of bigger and better quads. 

2. You Can Train One Leg At a Time

How does a hack squat work for the legs? Unlike the standard squat with a barbell, athletes can train one leg at a time. This option can aid in building muscle mass and definition.

3. It Will Help You Lift More 

What do hack squats work to build muscle and strength? By isolating these large muscle groups in the legs, you can lift more weight in less training time. Athletes can also handle heavier weight since they do not need to focus much on stability during the movement. 

4. Makes Your Knees Stronger

Contrary to some beliefs, the hack squat can help make your knees stronger for heavier weights when done correctly. Proper foot placement is essential to ensure no added stress on the knee joints. 

5. Lowers the Risk Of a Lower Back Injury

Since athletes lean back into the hack squat while the hips remain stable, there is less chance for a lower back injury during the movement. 

What are the Mistakes for Hack Squat Form?

Naturally, Hack squat Mistakes can happen with any exercise. However, avoiding common mistakes with a good hack squat form can help keep you injury-free in the gym. 

  1. Not Making Adjustments: The hack squat machine gym-goers may use should have capabilities to adjust the safety handles and other features. If you do not set up the machine to suit your height and size, you risk injury and not using proper form. 
  2. Using Too Much Weight: Your hack squat form can suffer when you try to squat using too much weight. Remember to build up slowly and ensure that you move through the movement correctly before adding more weight. 
  3. Foot Placement Is Wrong: Foot placement is highly critical when completing the hack squat. If the feet are too close together, there is a risk of increased knee stress during execution. 

How To Determine Proper Weight for Hack Squat

The hack squat machine can be useful for athletes who want to increase weight without stress injuries. Although determining the proper weight is crucial, there is still a risk of harm.

Athletes should familiarize themselves with the machine and its movement before adding weight. A warm-up rep or two should use about 40 or 50% of your typical barbell squat weight. 

Once you are comfortable, add the maximum weight typical for a standard squat. If you still feel comfortable, you can slowly include more weight until you cannot execute the proper form. If your positioning is failing, lighten the weight. 

Which Muscles Are Involved While Performing a Hack Squat?

So, what muscle does the hack squat work? This compound movement is terrific for training multiple muscle groups at once. 

Because of the standing angle and foot placement, the quads are activated more than standard squat movements.  

When pushing through the feet to lift the weight back up to a standing position, more power is needed from the hamstrings and the glutes. 

Although the hips are more immobile due to the back placement in the hack squat machine, the hip flexors are still necessary while bending the knees due to the wider foot placement.  

The core muscle along with the erector spinae provides support for the back and hip flexors during this movement.
