Lifting 5kg dumbbells is unlikely to stunt growth in individuals who are still in their growing years. The myth that weightlifting can stunt growth primarily stems from concerns about potential damage to growth plates, which are areas of developing cartilage found near the ends of long bones in children and adolescents.

In reality, weightlifting or resistance training with appropriate form, technique, and load does not pose a significant risk to growth plates. As long as the exercises are performed with proper technique, under appropriate supervision or guidance, and with weights that are suitable for the individual’s strength and development level, there should not be a concern for stunted growth.

In fact, engaging in age-appropriate resistance training can offer numerous benefits for young individuals, including improved muscular strength, bone health, and overall fitness. It’s important to emphasize proper form and technique during weightlifting exercises, start with lighter loads, and gradually progress as strength and coordination improve.

If you have any concerns about weightlifting or resistance training during the growth years, it’s advisable to consult with a qualified fitness professional or strength coach who can provide guidance based on individual circumstances and age-specific recommendations.
