You do not need to spend a lot of money exercise. You can run or play sports in a park or in your school gym. You don’t need to buy exercise equipment for your home. Just get your body moving!
· Don’t work too hard.
Choose a sport that you enjoy and then your exercise will be fun instead of work. Also, you only need to exercise a few times each week. If you exercise for 30 minutes each time, you will stay healthy.
· Drink enough water.
It is important to drink water when you exercise. Your body needs the water for energy and for keeping cool.
· Be careful!
If you hurt yourself while you are exercising, rest until you feel better. Exercising when you are hurt is bad for your health.
