Exercising is a good way to keep fit. However, many people do not know how to exercise well. Here are some tips.

    First, you should warm up. It is important to warm up before you exercise. You need to stretch your legs, arms, back and neck before you do any difficult activities like running.

    Second, you should find good places to exercise. You do not need to spend a lot of money. You can run or do 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. 

    Third, 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 30 minutes each time, you will stay healthy.

    Fourth, drink enough water. It is important to drink water when you exercise. Your body needs the water for energy and for keeping cool.

    Finally, you must 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.
