　　The key to reaching or staying at a healthy weight is regular exercise and good eating habits．Teens should get 60 minutes or more of physical activity a day．Note the word“activity”．As long as you’re getting your body moving, it dosen’t have to mean doing complicated exercises or going to the gym every day．All that matters is that each week you get the right balance of activity, including aerobic(有氧健身法的)，strength building, and flexibility(柔韧性)exercise．Make exercise a habit by scheduling some every day．

　　On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more．But most of us are busy, and 60 minutes a day of activity seems like a lot of time．The good news is that it’s OK to divide it into shorter“exercise breaks” throughout the day．

　　Just as you might have a healthy snack to stop yourself getting hungry, exercise snacks can keep energy level high．So get up 15minutes early and do some yoga or other stretching(伸展)activity．Fast walk or jog for 15 minutes at lunch．Do the same thing after school ---or walk or bike home．Add to that taking the stairs, gym class, and walking between classes during the day, and your’ve probably reached your 60 minutes．

　　Here are 5 simple ways to make an exercise lifestyle change：

　　1．Start today．Go outside for a walk．

　　2．Take the stairs instead of the elevator．

　　3．Instead of driving, walk or bike to places like school or a friend’s house．

　　4．Vacuum(用真空吸尘器清扫)your room, wash the car, or mow the lawn．

　　5．Limit your time watching TV, using the computer, or playing video games－and when you do play, try interactive games that get you moving．
