Children ages 12 to 17 need at least 60 minutes of moderate to vigorous intensity, aerobic physical activity daily. They also need to add muscle and bone strengthening exercises at least 3 days per week.
At this age, the child should have the confidence and competence to execute a variety of movements (throwing, catching, striking, and jumping) in various environments (snow, water, land). A lack of confidence in their ability compounded by the insecurities of puberty is a phase where the teen is most likely to drop out of physical activity participation.
