Do Squats Make You Shorter?

In reality, squats are a foundational exercise that strengthens the lower body and core, contributing to better posture and spinal alignment when performed correctly. While temporary compression of intervertebral discs may occur during intense lifting—leading to minor, reversible height fluctuations—scientific research shows no evidence that squatting causes permanent height loss. Understanding the difference between perceived and real effects, supported by proper form and recovery practices, is essential. In this article, we’ll explore the origin of the height loss myth, analyze the biomechanics of squatting, and clarify how this powerful movement affects your body over time.

How Squats Affect the Spine and Skeletal System

Squats exert significant axial load on the spine, directly influencing vertebral discs and overall skeletal alignment. During a properly executed squat, compressive forces are transmitted through the lumbar spine due to the vertical stacking of the barbell weight along the spinal column. This axial loading increases intradiscal pressure, especially in the L4-L5 and L5-S1 intervertebral discs, which are structurally most susceptible to degenerative changes. As depth increases in a squat, the hip flexion angle intensifies, shifting load distribution and affecting vertebral alignment. According to biomechanical studies, spinal compression forces during heavy squats can exceed 6–10 times body weight, depending on form, load, and individual anthropometrics (Schoenfeld, 2010). This highlights the importance of spinal neutrality and muscular bracing to mitigate risk of disc herniation and chronic postural strain.

Squat biomechanics influence musculoskeletal health by altering vertebrae alignment and spinal tension. The muscles of the posterior chain, particularly the erector spinae and gluteals, provide dynamic support, but poor squat mechanics—such as lumbar flexion under load—can compromise intervertebral space and heighten spinal compression risk. Repetitive loading without adequate spinal decompression or mobility work may lead to cumulative stress on the skeletal system, particularly within the thoracolumbar junction. Conversely, controlled squatting under optimal form can enhance postural integrity, strengthen the core-lumbar stabilizers, and improve vertebrae alignment, contributing positively to spine health. For injury prevention, integrating periodized loading strategies, mobility drills, and recovery techniques is essential in managing spine load during squats.

Temporary vs. Permanent Height Loss from Squats

Squats can cause temporary height loss due to spinal compression, not permanent shrinkage. During heavy lifting, axial loading compresses the spine, especially the intervertebral discs, which act as shock-absorbing cushions between vertebrae. This compression expels intervertebral fluid, reducing disc height and contributing to short-term height fluctuation—typically 1 to 2 centimeters. However, this is a reversible compression process, aligned with the natural diurnal height variation observed from morning to evening due to gravity.

Recovery begins once the load is removed. Spine rehydration occurs during rest, especially during sleep, as cartilage discs draw fluid back in through osmotic pressure. Within several hours to a full night's sleep, height is typically restored. Research published in the Journal of Applied Physiology confirms that disc compression from squats is temporary and does not contribute to permanent stature reduction. Key factors affecting recovery include hydration, spinal mobility, and overall disc health. Thus, while you may shrink after a workout, your height returns post-exercise, confirming that daily height change is normal and not a sign of long-term damage.

The Science Behind Spinal Compression During Lifting

Spinal compression in weightlifting occurs when vertical loads exert axial force along the spine, primarily during compound lifts like squats and deadlifts. According to Newton’s Second Law (F = ma), the downward force from a barbell increases with the weight and acceleration during movement. This generates significant axial compression, which is a concentrated force pressing along the spine’s length. The biomechanics of squats reveal that this load is not just static but dynamically amplified by the lifter’s movement, barbell position, and form. For example, in a 100 kg back squat, spinal load can exceed 700 kg due to mechanical leverage and intra-abdominal pressure changes. Proper alignment of force vectors through the spine is essential for safe load transfer and injury prevention.

When lifting, the spine acts as a load-bearing column, with intra-abdominal pressure functioning as an internal brace to counterbalance external forces. This pressure increases with diaphragmatic breathing and bracing, effectively distributing load and reducing spinal shear. However, poor lifting mechanics—such as a forward-leaning torso—shift force direction, increasing shear and compression at the lumbar vertebrae. The role of spinal load calculation becomes crucial in programming and rehabilitation to avoid overtraining injuries. Research published in the Journal of Biomechanics quantifies peak compressive loads on the spine during barbell back squats, with experienced lifters averaging 8 to 10 times body weight at peak exertion. This underscores the need for correct weightlifting form and load progression, especially when training under high intensities.

Does Squatting Stunt Growth in Teenagers?

Squatting does not stunt growth in teenagers when performed with proper technique and supervision. The myth that squats damage growth plates—also called epiphyseal plates—stems from a misunderstanding of skeletal development during puberty. Growth plates are areas of cartilage near the ends of long bones where bone growth occurs. They remain vulnerable during adolescence but are not inherently damaged by resistance training. According to the National Strength and Conditioning Association (NSCA), properly structured strength programs are safe for youth and can actually support musculoskeletal development and reduce injury risk when guided by qualified professionals.

Skeletal maturity and training safety depend more on load, form, and supervision than on the squat itself. Studies published in the British Journal of Sports Medicine show that resistance training in youth, including movements like squats, does not negatively impact height or growth velocity. Instead, when aligned with age-appropriate guidelines, adolescent lifting can improve coordination, bone density, and strength. Teenagers benefit from progressive training models that account for skeletal maturity and mitigate risk of growth plate injury. Emphasizing technique, controlled progression, and recovery ensures that squatting becomes a tool for long-term athletic development—not a growth hazard.

Postural Gains vs. Height Myths in Squatting

Squats improve posture, not actual height. The perceived increase in height after consistent squat training stems from improved spinal alignment and reduced muscular imbalances—not skeletal growth. As posture corrects through enhanced core strength and glute engagement, individuals often stand taller due to restored spinal curvature and reduced anterior pelvic tilt. This creates a height illusion, which is biomechanical rather than biological. According to a 2017 study in the Journal of Physical Therapy Science, corrective strength training led to significant postural improvements in over 80% of participants, especially those incorporating compound movements like squats.

Misinterpreting postural gains as height increase is a common misconception, particularly when new lifters experience reduced slouching after squats. Improved muscle tension regulation, especially in the hip flexors and erector spinae, helps maintain upright posture, reinforcing the visual effect of added height. However, spine alignment benefits should not be equated with vertical growth. Functional fitness disciplines emphasize this distinction, framing posture enhancement as a mobility and structural integrity gain rather than anatomical elongation. To maintain these benefits, athletes should integrate squats within a balanced routine targeting muscular symmetry and core stabilization, ensuring sustainable posture correction without perpetuating height myths.

How to squat properly?

Step 1: Set Up Your Stance

Begin by positioning your feet shoulder-width apart or slightly wider. Point your toes slightly outward at a comfortable angle. This initial stance is crucial for optimizing the engagement of your lower body muscles.

Step 2: Engage Your Core

Before executing the squat, it's essential to activate your core muscles to safeguard your spine and minimize the risk of injury. Take a deep breath as if preparing to withstand a punch to the stomach, and then tighten and engage your core.

Step 3: Descend Gracefully

Initiate the squat by pushing your hips back while simultaneously bending your knees. Maintain an upright chest and a straight back throughout the movement, all while keeping your core engaged. Lower your body until your thighs are parallel to the ground or even lower, if possible. Ensure that your knees remain aligned with your toes, and evenly distribute your weight across your feet.

Step 4: Rise with Control

Push through your heels and extend both your hips and knees to return to the starting position. As you reach the top, squeeze your glutes for maximum activation. Repeat this sequence for your desired number of repetitions.

Things to consider when squatting

Foot Placement

Earlier, we emphasized the importance of positioning your feet shoulder-width apart on the ground. However, it's crucial to understand that the optimal foot placement can vary significantly among individuals due to differences in anatomy. Therefore, don't hesitate to experiment with various foot positions to discover what offers the best combination of comfort and effectiveness for your unique body.

Range of Motion

Ideally, your squat should descend until your thighs are parallel to the ground. Yet, achieving this level of flexibility and mobility may not be immediate for everyone. If you find it challenging to reach the desired depth, consider incorporating mobility exercises into your warm-up routine. Exercises like hip flexor stretches and ankle mobility drills can be particularly advantageous in improving your squat depth over time.

Breathing Technique

Breathing is often an underestimated aspect of maintaining proper squat form. To enhance your squat performance, remember to take a deep breath before you initiate the squat and exhale as you rise from the squat. This controlled breathing pattern can provide stability and assist you in maintaining the correct form throughout the exercise, enabling you to lift more effectively.

Bar Placement

For those using a barbell during squats, the placement of the bar on your back can significantly influence your form and comfort. High bar squats tend to put more emphasis on the quadriceps, while low bar squats shift the focus to the posterior chain. It's worthwhile to experiment with both bar placements to determine which one feels most comfortable and effective for your body's specific mechanics and goals.

Which exercises should you combine with squats to support height growth?

Step Lunges

Step lunges are an excellent addition to your routine, as they target your leg and glute muscles, thereby enhancing your posture, alignment, and the potential for height gain. Begin by standing with your feet positioned shoulder-width apart. Take a step forward with one foot and lower your body until your leading knee forms a 90-degree angle. Return to your initial position and repeat the motion with the other leg.

Planks for Core Strength

Planks serve as a valuable exercise for bolstering your core strength and refining your overall posture. Assume a push-up position, with your hands placed shoulder-width apart and your feet together. Maintain a straight line from your head to your heels, engaging your core muscles, and sustain this position for a duration of 30 seconds to a full minute.

Calf Raises

The performance of calf raises can contribute to the visual impression of longer legs by specifically targeting the calf muscles. To execute this exercise, stand with your feet positioned shoulder-width apart. Elevate your heels off the ground, then lower them back down, and repeat this action.

Empower with Deadlifts

Incorporating deadlifts into your workout regimen is an intelligent choice, as they encompass a comprehensive workout that fortifies the muscles and bones crucial for height augmentation. Start by standing with your feet positioned shoulder-width apart. Bend down to grasp a barbell or dumbbell with your hands. Elevate the weight off the ground by extending your hips and standing upright, then carefully lower it back down to the ground, and replicate the movement.

Should children and adolescents practice squatting?

Squats can have several potential benefits for children and adolescents, including improved sports performance, increased bone density, and decreased risk of injury. Additionally, this exercise may help strengthen their overall fitness and contribute to a healthy lifestyle.

Potential risks of squats

While squats are generally considered a safe and effective workout, there are some potential risks associated with improper form or excessive weight.

Hurting your lower back is a common risk when squatting. It happens if the weight is lifted incorrectly or your back is not kept straight. Also, your knees might get hurt if they are not aligned properly or if there is excessive stress on knee joints.

To minimize these risks, children and adolescents need to learn proper squatting techniques and start with lighter weights or bodyweight exercises before progressing to heavier weights.

Guidelines for squatting

• Before adding weight to the squat, you should know the basics and how to perform bodyweight squats to build strength and confidence.

• Remember that carrying out the correct technique is essential for preventing injury and maximizing the benefits of the exercise. Always keep your back straight, knees aligned over your toes, and lower yourself down until your thighs are parallel to the ground.

• Once the proper technique has been mastered, you can start to add weight to the squat. But try to begin with lighter weights and then increase the weight over time.

• Make sure you are supervised by a qualified trainer or coach when performing squats, especially when using heavier weights.

To sum up,

In conclusion, it's important to note that engaging in squats does not result in a decrease in your height. However, incorporating squats into your fitness routine can yield a multitude of benefits beyond simply avoiding height reduction. Squats can significantly enhance lower body strength, elevate your overall fitness, and even contribute to the enhancement of your posture, thereby creating the illusion of increased height.
