The squat vs leg press debate has run rampant for years now, and it seems as though every fitness expert has their own opinion.  

But what does the science say? 

This is a good question, and it is one that we are going to take a look right into it.  

Let’s get right into it and take a look at the squat vs leg press.  

How Do Leg Presses And Squats Differ From Each Other? 

Leg presses and squats are two popular lower body exercises, but they differ in terms of movement, muscles used, and the overall training experience. 

While both leg presses and squats target the same muscles, that’s not to say they are both as effective as one another.  

To be forthright; squats are superior to leg presses in almost every way. 

Squats allow for a greater range of motion, higher muscle recruitment, the development of stabilisation muscles, and much more.  

Meanwhile, leg presses tend to be safer than squats and better for people with certain injuries or pain, so this is something to keep in mind.  

Leg Press vs. Squat: Muscles Used  

In a leg press, the movement primarily targets the quadriceps, hamstrings, and glutes. Since the movement is guided and stabilized by the machine, it allows you to focus on pushing heavy weights with less emphasis on stabilizing muscles. 

On the other hand, squats are compound movements that engage multiple muscle groups, including the quadriceps, hamstrings, glutes, core, and lower back. 

Squats also require greater stabilizing effort, making them more functional and effective for overall lower body development. 

Leg Press vs Squat: Hormonal Response  

When comparing the hormonal response between the two exercises, squats have been shown to produce higher levels of testosterone and growth hormone.  

These hormones play a crucial role in muscle growth and strength development, making squats more favorable for muscle building. 

Leg Press vs Squat: Sport Performance  

For athletes seeking enhanced sports performance, squats have the advantage. Squats improve functional strength, power, and explosiveness, translating well to various athletic movements and activities.  

The additional stabilization required during squats also mimics real-life situations better than leg presses. 

Leg Press vs Squat: Body Composition  

In terms of body composition changes, squats have the upper hand. Since squats engage more muscle groups and elevate heart rate, they burn more calories during and after the workout, contributing to fat loss and improved body composition. 

Leg Press vs Squat: Gaining Strength 

Both exercises can help build strength, but squats are generally more effective. The functional nature of squats recruits more muscle fibers and promotes greater strength gains compared to the leg press. 

Leg Presses vs. Squats: The Pros and Cons 

Leg Press Pros 

  • Less stress on the lower back and knees compared to squats. 
  • Isolates and targets specific leg muscles for hypertrophy. (This is one of the best leg press benefits for ladies). 
  • Suitable for beginners or those with certain mobility limitations. 
  • Easier to load with heavier weights due to machine support. 

Leg Press Cons 

  • Lacks functional carryover to daily life and sports. 
  • May not fully engage stabilizing muscles and core. 
  • Potential for improper form if not properly adjusted or used. 

The Pros And Cons Of Squats 

Squat Pros 

  • Full-body engagement, targeting multiple muscle groups. 
  • Improves functional strength and stability. 
  • Enhances balance, coordination, and athleticism. 
  • Triggers a higher hormonal response for muscle growth. 

Squat Cons 

  • Requires proper form and technique to prevent injury. 
  • May be challenging for those with mobility or flexibility issues. 
  • Heavier loads can put significant stress on the lower back and knees. 

Which Exercise Is Best Suited To You? 

When To Use The Squat? 

Choose squats when: 

  • You want to build overall lower body strength and muscle mass. 
  • You aim to improve sports performance and functional strength. 
  • You have good mobility and flexibility to perform squats safely. 
  • You seek a more time-efficient full-body exercise. 

When To Use The Leg Press? 

Opt for leg presses when: 

  • You want to target specific leg muscles for isolated hypertrophy. 
  • You are recovering from an injury and need a gentler leg exercise. 
  • You have limited mobility or struggle with squat form. 
  • You want to supplement your overall leg training with additional volume. 

When To Use Both? 

Incorporate both leg presses and squats into your training regimen for a well-rounded lower body workout.  

Begin with squats to engage multiple muscle groups and promote functional strength, then follow up with leg presses to target specific muscles and add volume to your leg routine. 

Leg Press Variations 

One-leg Leg Press 

Perform leg presses one leg at a time to address imbalances and increase stability demands. 

Higher Foot Placement 

Place your feet higher on the leg press platform to target the glutes and hamstrings. 

Lower Foot Placement 

Position your feet lower on the platform to emphasize the quadriceps. 

Squat variations 

Back squats 

Perform traditional squats with a barbell on your upper back. 

Hack squats 

Use a hack squat machine or a barbell behind your legs for targeted quad work. 

Smith machine squat 

Smith machine squats can allow people with weaker or painful joints to squat. 

The leg press vs smith machine squat is pretty controversial, but smith machine squats are still likely going to be better for muscle mass and strength.  

Front squats 

Rest the barbell across your front shoulders for greater emphasis on the quads. 

How Much Should You Be Able To Leg Press? 

Male 

As a general guideline, an average male should be able to leg press around 2.5 times his body weight for one repetition. 

Female 

On average, a female should be able to leg press around 1.9 times her body weight for one repetition. 

How Much Should You Be Able To Back Squat?

Male 

An average male should be able to back squat around 1.5 times his body weight for one repetition. 

Female 

An average female should be able to back squat around 1.0 to 1.2 times her body weight for one repetition. 

The Tall Guy Conundrum 

Tall individuals may face challenges with both leg presses and squats due to their longer limb lengths. For squats, tall individuals may struggle with maintaining proper form and balance.  

On the other hand, the leg press machine may not be adequately adjusted for taller users, leading to discomfort and limited range of motion. 

To accommodate tall individuals, proper equipment setup and adjustments are crucial. Additionally, incorporating exercises that target leg muscles effectively with less reliance on equipment can be beneficial. 

Safety Tips 

Regardless of the exercise you choose, safety should always be a priority. Follow these tips to perform leg presses and squats safely: 

  • Warm-up adequately before starting your leg workout to prepare your muscles and joints. 
  • Use proper form and technique to avoid injury. Seek guidance from a qualified trainer if needed. 
  • Start with lighter weights and gradually progress to heavier loads to prevent overexertion. 
  • Use a spotter for squats and heavy leg press machine exercises, especially if you’re lifting near your maximum capacity. 
  • Listen to your body and avoid pushing through pain or discomfort. Rest and recover as needed. 

The Bottom Line 

Both leg presses and squats offer unique benefits and have their place in a well-rounded leg training routine.  

Squats are superior for overall strength, muscle engagement, and functional carryover, making them an essential compound exercise.  

Leg presses are effective for isolating specific leg muscles and can be valuable for individuals with certain limitations. 

To maximize leg muscle growth and strength development, consider incorporating both exercises into your workouts strategically.  

Combine compound movements like squats with targeted exercises like leg presses to achieve a balanced and effective leg training routine. Remember to prioritize safety, proper form, and gradual progression to achieve the best results while minimizing the risk of injury. Happy lifting!
