The leg press and hack squat are two commonly used machine exercises by people while working out for their lower body. Both exercises, assisted by machines, perform similar functions, like building strength, size, and definition in the lower part of the body. However, although they perform identical benefits, their work on the body somewhat differs. Therefore, choosing proper machine-based exercises for specific goals will help gain better results.  

One of the most common versions of the squat is the machine hack. It’s a leg workout that is performed upright and activates a variety of lower-body muscles. According to research, hack squats work the same muscles as back squats. But, compared to other machines, this one focuses on your knees and quadriceps, strengthening them more and encouraging hypertrophy. Conversely, the leg press isolates your core and concentrates only on your legs. It’s among the greatest workouts for building stronger legs.

Key Takeaways

  1. Muscle Engagement: Leg press primarily targets the quadriceps and glutes, while hack squat engages a wider range including the core and back.
  2. Machine Availability: Leg press machines are common, and hack squat machines are rare, impacting exercise selection.
  3. Risk and Stabilization: Leg press may be perceived as safer; hack squat requires more stabilization and potentially higher injury risk.

The Leg Press Machine

Different variations, such as traditional, vertical, and horizontal leg presses, are available on the market. While working on a vertical leg press machine, the loads will be pressed from the back of the person as the base, while a horizontal leg press keeps the person seated with an upright torso. Most of these variations will be available in all commercial gyms.

However, the most common variation of the leg press is the 45-degree leg press, in which the person lies against a back pad with their legs angled upwards at 45 degrees. This machine can alter the foot width to work different leg muscles. This machine is advantageous for anyone wishing to add a high-volume or heavy-weight exercise to their leg routines and for those who find it difficult to perform traditional squats.

Pros And Cons Of Leg Press Machine


  • Beginners will find it simple and easy to learn.
  • The risk of injury is less as it does not demand stability and balance.
  • Outstanding isolation of the leg muscles, especially the quads.
  • A good substitute for people with shoulder and lower back problems.
  • With this routine, it’s safe to train yourself to failure.
  • A leg press allows most people to lift more weight than a squat. 
  • By focusing on one leg at a time, the leg press can be used to correct muscular imbalances or strength issues.
  • By changing the leg placements, specific muscles can be targeted.
  • Leg press equipment is found in most commercial gyms.
  • The back support makes it more comfortable than the hack squat.
  • More than the hack squat, it focuses on the hamstrings.  


  • The machine would provide a limited range of action for taller people.
  • It doesn’t strengthen other stabilizing muscles or build abs.
  • Using larger weights might limit the range of motion by not engaging the muscles to their maximum potential.
  • Leg press machines vary throughout gyms in terms of their effectiveness in targeting different muscle groups.
  • Compared to the hack squat, the seated leg press allows one to lift larger weights, leading to more spine compression.

The Hack Squat Machine

One of the finest substitutes for the leg press is the hack squat. Similar to a traditional barbell squat, this machine transfers the weight onto one’s shoulders while lessening the pressure on their exterior muscle groups. Due to this, when a person loads more weight and advances through a workout, the hack squat focuses on their quads, glutes, and hamstrings, lowering the chance of injury and bad form.

Pros And Cons Of Hack Squat


  • The hack squat engages more muscles than the leg press.
  • It provides more effective, targeted training for barbell squats.
  • less chance of damage compared to other squats because the spine is not stressed much.
  • Excellent for beginners learning squats.
  • Because the machine contains safety catches, it is appropriate for training to failure.
  • Better than a leg press for strengthening the quadriceps
  • Putting the weight on the shoulders helps distribute it better.


  • Heavy-weight hack squats can be taxing on the back and shoulders.
  • This exercise regimen is intricate and may prove difficult for beginners.
  • For those who are taller than usual, the fixed position of the hack squat machine can be uncomfortable. 
  • Hack-squat machines are not commonly found in commercial gyms.
  • With this routine, you cannot train one leg at a time.
  • In contrast to a barbell squat, it does not strengthen the stabilizer muscles.
  • Compared to the leg press, the hack squat carries a larger risk of injury.

Difference Between Leg Press And Hack Squat

The leg press and the hack squat machine are two popular options for leg day. Both exercises safely and effectively work the lower body, but they differ in a few important ways that set them apart. Using the feet to drive weights away from the body, the leg press is a machine-based workout.

The hack squat machine, on the other hand, requires the user to squat down while pressing upward and away from a foot plate with all their weight on their shoulders. The major differences between the two machines are in their biomechanics, load placement, and target muscles.

  • Even though the legs are the main focus, in the leg press, the whole body is pushed upward against gravity, while in the hack squat, the legs push the weight and the body on the shoulders, giving more strain to the knees.
  • The leg press machines are common, but the hack squat machines are rare.
  • The quadriceps and glutes are mainly targeted during the hack squat and leg press. Additionally, these exercises work the hamstrings and calves. On the other hand, the axial loading of the hack squat engages the core and back muscles. 
  • The leg press does not replicate the traditional barbell squat, whereas the hack squat machine does.

Although the leg press and hack squat machines possess some differences, they are similar. The hack squat closely resembles the back squat since it has a shoulder-loaded weight capacity, but the leg press demands the user push a foot plate away from them. While there are advantages and disadvantages to each machine, they may all be utilized to target and isolate the lower body muscles for daily benefits, increased muscle size and strength, and improved performance in other compound motions such as the squat. However, it is important to take the necessary precautions and ensure safety while using both exercise machines.
