Many teens suffer from a lack of self-confidence, due at least in part to insecurity about their bodies. The Centers for Disease Control and Prevention indicates teens should get at least one hour of exercise a day to be fit, however only one in every 10 teens is getting this amount of exercise. For an insecure teen, watching television, playing video games and surfing the Internet can offer temporary comfort, but actually erode self-confidence in the long-term as they promote an inactive lifestyle.
Exercise tones the muscles, makes the bones stronger and lowers body fat, according to the Mayo clinic. In short, being fit makes you more attractive. An attractive teen is more likely to be self-confident. Other physical benefits of exercise include strengthening the heart, increasing lung capacity and boosting the immune system, thus making you healthier. A healthier teen is more likely to be an active participant in school, giving him more opportunities to build his self-confidence.
