Why is it important that 14 16 year olds avoid high intensity weight training?

It is important for 14 to 16-year-olds to avoid high-intensity weight training because their bodies are still developing, and excessive strain can lead to injuries or long-term damage. During this growth phase, their bones, muscles, and connective tissues are more vulnerable, making them less capable of handling heavy weights. Instead, focusing on proper technique, bodyweight exercises, and light resistance can promote strength and fitness while minimizing risks. Additionally, engaging in a variety of physical activities helps ensure balanced development.
