Does lifting weights stunt growth?
Properly supervised, age-appropriate strength training is not known to stunt growth. The concern is not lifting itself; it is poor supervision, inappropriate loads, unsafe technique, or treating children like adult powerlifters.
Youth training should emphasize movement skill, control, gradual progression, enjoyment, and broad athletic development. Maximal testing and ego lifting are not necessary.
Parents should involve qualified coaches and clinicians when needed, especially for adolescents with medical conditions, pain, or sport-specific demands. The goal is safe competence, not adult-style intensity.
