Lifting weights inhibits growth in teens and children
Scientific evidence refutes the long-standing myth that weightlifting and resistance training inhibit growth in children and teenagers; instead, properly supervised resistance training is safe, beneficial for development, and improves muscular fitness without stunting height.
The claim that lifting weights inhibits growth in teens and children is a well-known athletic myth. Retrieved papers such as [0], [3], and [11] explicitly address youth resistance training, showing that it is safe, beneficial, and supports normal growth and endocrine function rather than inhibiting development. Therefore, the claim is clearly refuted by the scientific literature.

This scoping review demonstrates that resistance training is safe and effective for youth athletes, improving muscular fitness and promoting long-term health without indicating negative effects on overall growth.

This randomized trial found that structured exercise in adolescents actually improved growth parameters, height, muscle mass, and growth hormone profiles rather than inhibiting them.
