joints, controlling weight, and preventing the development of high

Some studies suggest that physical activity may have other benefits

in team sports or are physically active outside of school are less likely
to engage in risky behaviors, like using drugs or smoking. Physical
activity does not need to be strenuous to be beneficial. The CDC rec-
ommends moderate, daily physical activity for people of all ages, such
as  brisk  walking  for  30  minutes  or  15–20  minutes  of  more  intense
exercise. A survey conducted by the National Association for Sport
and Physical Education questioned teens about their attitudes toward
exercise  and  about  what  it  would  take  to  get  them  moving.  Teens
chose friends (56%) as their most likely motivators for becoming more
active, followed by parents (18%) and professional athletes (11%).
