to lower the risks of many health problems, teens should aim for how many minutes of physical activity every day?

Children and adolescents aged 5-17 years  should do at least an average of 60 minutes per day of moderate-to-vigorous intensity, mostly aerobic, physical activity, across the week.  Children should incorporate vigorous-intensity aerobic activities, as well as those that strengthen muscle and bone, at least 3 days a week.
