I t's a general opinion that teenagers who train with weights will not grow taller.
Researchers dismiss this as a myth. However, a teenager should not use very heavy weights for certain exercises such as shoulder presses, squats and deadlifts when he or she starts training. This is because their bones may still be tender and poor form may lead to serious injury. Training with light and moderate weights is the way to begin. Proper training may actually help their bones grow stronger. A couple of years down the line, they can train with heavy weights.
