A teenager should exercise just as much as an adult should, which is 60 minutes a day. 30 of these said minutes can be spent simply walking to class in school. But then you ne â¦ ed another 30 minutes of hard exercise that will keep your heart pumping.
For example, a 15-year-old teen girl requires 1,800 calories if she is sedentary, 2,000 calories a day if she is moderately active and 2,400 calories daily if sheâs active â which means she exercises the equivalent of walking more than 3 miles daily at a pace of 3 to 4 miles per hour.
