take exercise---draft 2

Taking exercise is essential to me because it has a lot of advantages. First, people can lose weight by exercising. For many girls, it is a dream to lose weight in order to look beautiful. If these girls want to achieve their dreams, they have to take more exercise. Second, exercise can advance the blood circulation. Generally, people usually stay at home that is called a couch-potato. However, to be a couch-potato may lead to congestion of blood circulation which people must stand up for a while and move bodies to avoid this situation. The most important reason is that people can keep healthy. Having a healthy body will pay off a life. A longer life is treasure which let us have more time to do more valuable things. Therefore, taking exercise plays an significant role in our lives.
