teens(and younger) and weightlifting

teenagers and people who are younger can start weightlifting with adult supervision,but it is also dangerous for those that are younger because when you are younger and you start weightlifting what you are actually using is the muscles needed to help you grow so in-turn you may actually stunt your growth. so it is strongly advised that you talk to a doctor or someone that is familiar with muscles and which ones  help you grow and which ones help make you stronger.
