Does weight lifting stunt growth in kids under 18 (what does the science say)?
No. Weightlifting, when done safely and with proper form, is healthy and
not harmful to growth at all. Kids can develop pain and problems from
overuse if they do any activity too often, with too much intensity, or
with too little rest. Supervision and proper instruction are most important
to keep them safe.
Why do people believe that lifting weights stunts growth?
There's a lot of misinformation about many health topics. It's
important to ask your doctor before implementing or avoiding certain activities,
especially if recommendations are based on word of mouth or from unqualified sources.
Any tips for teenagers who want to lift weights?
Find a good coach, experienced in working with kids your age. If you lift
weights safely with good movement patterns and form - you will get stronger!
You won't get "bigger" until you get further into puberty,
but you will get much stronger.
What age is safe to start lifting weights?
Safety with weight lifting is all about maturity and proper supervision.
Age isn't as important. Make sure your athlete is mature enough to
follow safety rules and start building a healthy foundation of exercise
as young as possible.
