When Can Teenagers Start Lifting Weights?
There are few topics that cause as much conflict between myth and fact as climate change, but this one comes really close: at what age should a pre-teen or early teenager start lifting weights?
Will lifting weights stunt the growth of a teenager? If you research the topic online, you will see many opinions like "it may stunt growth," but you will not find any scientific research that backs them up. But, you will find many scientific studies and opinions based on research that say teenagers can lift within certain parameters.
Here is the question that prompted my response:
Stew, I am a 15 year Army veteran and my 13 year-old son wants to do some PT with me – even lift some weights. I have read some of your previous writing about how you started working out in your early teen years, so I'm pretty sure I know what your response will be. But is there any science out there that specifically shows that lifting weights in your early teens will not stunt your growth?
In a nutshell: yes, it is a myth. Unless a weight drops on your growth plate, you will not stunt your growth lifting weights. You have a greater chance of stunting growth by breaking bones near your growth plates by playing football, soccer, or gymnastics than by lifting weights. But don't take my word for it, check out scientific studies and books. Author of Strength and Power for Young Athletes, Dr. Avery Faigenbaum has performed research on the topic for years and produced this book. He states:
There are many benefits to starting children on a strength training program at an early age, including
- Increased strength and power
- Improved body composition
- Greater self-esteem
- Reduction in sports training injuries
- Enhanced sports performance
This proven, research-based book provides young people ages 7 to 15 with a solid fitness base and aerobic activities and stretching exercises. It also presents the principles and practical applications of developing both age and sport-specific strength-training programs.
This British Journal of Sports Medicine study has many elements and parameters for safety to a successful training program for young athletes.

My recommendation is to not start a young athlete on weights without a well-rounded athletic foundation. Take a solid year or more to work on a calisthenics-based program (pushups, pullups, dips, squats, lunges, plank poses and a variety of core exercises to name several) to build a solid foundation of resistance training without weights.
As you progress through the calisthenics base, start adding other gear such as dumbbells, barbell basics, suspension training (TRX), and even machines to progress logically to and through the overload process. Once you start allowing your child to lift weights, do not have them attempt your personal program. Consider technique and proper skills focus over than how much weight they can do – keep repetitions in the 10-15 rep set range.
As the new weight lifter progresses, I would also limit amount of weight lifted to below the early teen's body weight. Basically, keep the weight lifted under their body weight until perfect form can be developed and a need arises, most likely through sports, which requires heavier lifts.
