Why Lifting Weights Won't Stunt Your Athlete's Growth - Cedar Park Athlete Training

If you're a parent of a growing athlete, you've probably heard this before:

Lifting weights can stunt your child's growth!

It’s one of the most persistent fears out there—and it’s completely false.

Let’s break down why strength training is not only safe for teens, but one of the best things they can do for their development.

Where Did This Myth Come From?

The idea that weightlifting stunts growth likely came from outdated beliefs and a few misinterpreted injuries in poorly supervised environments.

But today, the science is clear.

There is zero evidence that strength training stunts growth when done correctly.

In fact, according to the American Academy of Pediatrics and the National Strength and Conditioning Association, properly designed youth strength programs are safe, effective, and recommended.

How Strength Training Supports Growth

Here’s what actually happens when teens lift weights under proper supervision:

• Increased bone density→ Resistance training stimulates bone growth, making bones stronger and more resilient.

  
  

• Improved joint stability→ Stronger muscles protect joints from injury, especially as sport demands increase.

  
  

• Better posture and movement patterns→ Essential during growth spurts when coordination can dip.

  
  

• Higher levels of natural growth hormones→ Strength training can stimulate the production of growth hormone, which supports physical development.

  
  

What Can Stunt Growth?

Here’s what actually poses a threat to a young athlete’s development:

• Poor sleep

• Chronic stress

• Under-eating (especially protein)

• Overuse injuries from only playing one sport year-round

• Lack of movement variety or physical literacy

• 
  

None of that has to do with lifting weights. In fact, a well-structured strength program helps address all of those issues.

Safety Comes Down to How They Train

Strength training is only dangerous when it’s:

• Poorly supervised

• Ego-driven

• Programmed for adults

• Focused only on max lifting with bad form
