The question of how deep to squat is one that is highly debated, with different experts giving different opinions.

But what does the science say? 

Well, that’s what we are going to take a look at in this article. 

Let’s dive right into it and take a look at how deep to squat based on scientific research.  

What Is a Deep Squat? 

A deep squat refers to a squatting position where the hips descend below the parallel of the knees.  

It involves a greater range of motion compared to a partial or shallow squat.  

In a deep squat, the thighs are parallel to the ground or lower, depending on an individual’s flexibility and comfort level. 

How Deep Should You Squat for Muscle Growth? 

When it comes to muscle growth, incorporating a variety of squat depths in your training can be beneficial.  

Deep squats engage the muscles of the lower body, including the quadriceps, hamstrings, glutes, and even the calves to a certain extent.  

Going deep in your squats allows for greater activation of these muscles, leading to potential gains in muscle size and strength. 

Research on the 90 degree squat vs full squat suggests that going at least parallel (where the hip joint is in line with the knee joint) can activate the muscles effectively. 

However, going beyond parallel and performing deep squats can further enhance muscle activation and recruitment, stimulating greater hypertrophy.  

So, if your mobility allows, aiming for a deep squat position can be advantageous for muscle growth. 

How Deep Should You Squat for Strength? 

When it comes to building strength, squat depth becomes an important consideration.  

Powerlifters and strength athletes often prioritize squatting to parallel or just below parallel. This range allows them to lift heavier loads and maximize their strength potential. 

Squatting to parallel is commonly used in strength training programs as it allows for optimal engagement of the major lower body muscles while maintaining stability and control.  

This depth provides a balance between muscle activation, joint stability, and the ability to lift heavy weights, which is crucial for strength development. 

What Is Powerlifting Squat Depth? 

In powerlifting competitions, powerlifting squat depth may vary based on the federation’s rules and regulations.  

Generally, powerlifting requires squatting to at least parallel or breaking parallel, where the hip crease is below the top surface of the knee.  

Meeting the depth requirement is essential for a successful lift in powerlifting competitions. 

Powerlifters focus on maximizing their strength in the squat, and adhering to the specific depth guidelines ensures fair judging and uniformity among competitors.  

It also emphasizes the ability to generate force from a specific range of motion, testing the lifter’s strength and technique under strict standards. 

Are Deep Squats Dangerous? 

One of the most common arguments when it comes to deep squats vs normal squats is that deep squats are more dangerous than their less strenuous counterpart.  

 However, when performed with proper form, appropriate progression, and within an individual’s range of motion, deep squats are generally considered safe for most individuals. 

Contrary to popular belief, deep squats do not inherently increase the risk of knee injuries.  

In fact, research indicates that deep squats can improve knee stability by strengthening the surrounding muscles and connective tissues.  

They also promote balanced muscle development throughout the lower body, which can help reduce the risk of imbalances and potential injuries. 

That being said, individuals with pre-existing knee issues, limited mobility, or specific conditions should consult with a healthcare professional or qualified trainer before attempting deep squats.  

They can provide personalized guidance and modifications based on individual needs and circumstances. 

How Low to Squat 

Determining how low to squat depends on several factors, including individual mobility, training goals, and comfort level.  

As mentioned earlier, going to at least parallel (hip joint in line with the knee joint) is a good starting point for most individuals. 

If you have the flexibility and feel comfortable, progressing to a deep squat position, where the hips descend below parallel, can provide additional benefits.  

This deeper range of motion can further engage the muscles of the lower body and challenge your stability. 

However, it’s crucial to maintain proper form throughout the entire squat movement.  

Avoid excessive rounding of the lower back or allowing the knees to cave inward. Focus on engaging the core, keeping the chest up, and distributing the weight evenly through your feet. 

Conclusion and Practical Applications 

The depth of your squat should be based on your individual goals and capabilities. For muscle growth, incorporating deep squats can provide increased muscle activation and potential hypertrophy.  

If you’re focused on strength development, squatting to parallel or just below parallel is typically sufficient for maximizing strength gains. 

Remember, proper form, gradual progression, and listening to your body are key. 

Always warm up adequately, prioritize mobility exercises, and engage in regular strength training to improve your squat depth and overall performance. 

It’s also worth mentioning that squat depth alone is not the sole determinant of a successful and effective workout.  

A well-rounded training program that includes other exercises targeting different muscle groups, mobility work, and recovery strategies is essential for overall fitness and injury prevention. 

As with any exercise, individual differences exist, and what works for one person may not work for another.  

If you’re unsure about the depth of your squats or have specific concerns, it’s always a good idea to seek guidance from a qualified fitness professional who can assess your form, mobility, and individual needs. 

How Deep To Squat – FAQs 


1. “Won’t Squatting Deep Put Excessive Strain on My Knees?” 

No, squatting deep will not put excessive strain on your knees if you practise proper form. 

However, if you do experience knee pain while squatting, you may want to find a more suitable alternative.  

2. “I’ll Have To Drop The Weights Considerably To Squat Below Parallel. Isn’t Using Heavier Weights Better?” 

No, using heavier weights isn’t better. 

Squatting below parallel is much better for muscle and strength growth, so even though you may have to drop the weight, you are going to be better off.  

3. “What If I Can’t Squat Below Parallel Without My Back Rounding Or Hurting?” 

If you can’t squat below parallel without your back rounding or hurting, you should go as deep as you can without pain and slowly improve your depth over time.  

4. “Should You Squat Past 90 Degrees?” 

Yes, you should squat past 90 degrees. 

Data shows that muscle activation is much higher if you squat past 90 degrees.  

However, there are exceptions, such as those who have genuine mobility issues.  

5. “How Deep Should I Squat From Behind?” 

You should squat so your glutes pass your knees for maximum effectiveness.  

6. “Is It Possible To Squat Too Deep?” 

No, it is not possible to squat too deep. 

The deeper you can go without sacrificing form, the better. 

However, there may be some people who have specific mobility issues or disabilities that may be better off not squatting as deep as possible.  

7. “Should You Go All The Way Down On Squats?” 

Yes, you should go all the way down on squats.  

This leads to improved muscle and strength gains.  

8. “Can You Squat Too Low?” 

No, you can’t squat too low. 

This is barring those with mobility issues or injuries.  

9. “How To Tell If You’re Squatting Low Enough?” 

You can tell if you are squatting low enough if you are squatting at least parallel but preferably more.  

10. “How Low Should You Squat for Glutes?” 

You should aim to squat as low as you can for glutes.  

The deeper you go, the larger the range of motion and the more muscle that is activated.  

11. “Are Deep Squats Bad For Your Knees?” 

No, deep squats are not bad for your knees when performed correctly.  

If you tense your entire body throughout the movement and have a good stance, your glutes and quads will be taking most of the load.  

We hope we have been able to help you. 

While the answer to how deep to squat will vary for everyone, as a general rule of thumb, you will want to go to at least parallel to maximise muscle and strength gains.
