Does Lifting Weights Stunt Growth in Children and Adolescents?

6V7gCt

You’ve probably heard it before.

“Don’t let your kids lift weights - it’ll stunt their growth.”

It’s one of the most common myths in youth sports. Parents worry. Coaches hesitate. Teenagers second-guess whether they should start training.

So let’s answer it clearly:

Does lifting weights stunt growth?
No - properly supervised weight training does not stunt growth.

Now let’s break down why that myth still exists and what science actually says.


Where Did the “Lifting Weights Stunts Growth” Myth Come From?

The concern usually centres around growth plates, the areas of developing tissue near the ends of long bones in children and adolescents.

Because growth plates are still developing, people assume they’re fragile and easily damaged by strength training.

Here’s the important distinction:

Poorly supervised training, excessive load, or improper technique can increase injury risk.

But that’s true for any physical activity - including football, gymnastics, and even playground sport.

Modern research in sports medicine consistently shows that structured resistance training does not harm growth plates when appropriately programmed and supervised.


Is Weight Training Safe for Children and Adolescents?

Yes - when done correctly.

In fact, studies show that well-designed strength and conditioning programs for youth athletes often result in lower injury rates compared to many traditional sports.

The key factors are:

  • Qualified supervision

  • Age-appropriate programming

  • Gradual progression

  • Focus on technique

  • Emphasis on control, not maximal lifting

A proper strength training program for kids is not about lifting the heaviest weight possible. It’s about movement quality, coordination, and progressive development.

Training does not stunt growth when it is structured properly.


Does Working Out Stunt Growth?

Another common variation of the same question is: will working out stunt growth?

No.

Whether it’s body weight exercises, resistance bands, kettlebells, or light free weights, physical training supports overall development.

In fact, resistance training can improve:

  • Bone mineral density

  • Muscle strength

  • Coordination

  • Cardiovascular health

  • Confidence and self-esteem

Regular physical training supports athletic development, not the opposite.


What Actually Causes Growth Plate Injuries?

Growth plate injuries typically happen due to:

  • Acute trauma, such as falls or collisions

  • Overuse in high-volume sport

  • Poor recovery

  • Excessive load without supervision

Notice what’s missing?

Properly supervised resistance training.

In many cases, a structured strength and conditioning program can actually reduce the risk of injury by improving movement control and strength around joints.

Benefits of Youth Strength Training

A well-designed youth weight training program can improve:

Physical health

  • Stronger muscles and bones

  • Improved body composition

  • Better coordination

Performance

  • More power and speed

  • Better endurance

  • Improved sport-specific skills

Injury prevention

  • Reduced injury risk

  • Improved joint stability

  • Faster rehabilitation if injured

Long-term health

  • Higher likelihood of staying active into adulthood

  • Better confidence in physical activity

You do not need to play competitive sport to benefit.

Strength training using body weight, light resistance, and progressive load supports healthy development for all children and adolescents.


So… Would You Have Grown Taller If You Avoided Weights?

No.

Your height is primarily determined by genetics and nutrition - not whether you did squats at 14.

There is no evidence that lifting weights shortens final adult height when done properly.

If anything, resistance training improves bone health and musculoskeletal resilience.


When Should Kids Start Strength Training?

Children can begin learning structured movement patterns as soon as they can follow instructions - often around 7 - 8 years old - but the focus should be:

  • Movement skill

  • Body awareness

  • Body weight control

  • Fun and engagement

As they mature, load and complexity can gradually increase.

This is how safe, effective athletic development works.


Final Answer: Does Lifting Weights Stunt Growth?

No.

When properly supervised and age-appropriate, lifting weights does not stunt growth.

It improves strength, coordination, injury resilience, and long-term health.

The real risk isn’t strength training - it’s poorly structured training without guidance.
