Answer: The national physical activity guidelines for Americans recommend 60 minutes of activity each day for teens. Some of the recommended activity should be vigorous activity performed at least three days a week and some should be muscle fitness and bone-building activity performed at least two days a week.
Explanation:
In recognition of rising obesity rates in America, the US Department of Health and Human Services has recommended through the National Physical Activity Guidelines, that teens should perform at least an hour of moderate to vigorous exercises every day.
These exercises should include vigorous activity to be performed at least thrice a week and muscle fitness and bone-building exercises at least twice a week. These exercises should take into account that teens get bored quickly and therefore should be exciting and have variety.
