Fitness Benefits For Teens

  • Teens and young adults, both male and female, benefit from physical activity.
  • Physical activity does not need to be strenuous to be beneficial.
  • Moderate amounts of daily physical activity are recommended for people of all ages. This amount can be obtained in longer sessions of moderately intense activities, such as brisk walking for 30 minutes, or in shorter sessions of more intense activities, such as jogging or playing basketball for 15-20 minutes.
  • Greater amounts of physical activity are even more beneficial, up to a point. Excessive amounts of physical activity can lead to injuries, menstrual abnormalities, and bone weakening.

FACTS
