Your weight will not increase because your metabolism is making you burn calories faster
False. Adolescents need the same amount of physical activity that adults do. The only thing that varies is the beneficial effects that exercise brings and the overall physical effect it has to the body. Adolescents still have a fast metabolism which enables them to maintain their shape despite the amount of caloric intakes they've had while adults don't. Exercise duration should at least last for 30 minutes to induce physical fitness in the body and this works for young adults and mature adults alike.
