Now students in our country study hard every day. But it's very bad for our health. Health is very important and it's the foundation of one's success. So how to keep fit?

Firstly, we should spend time taking exercise every day to strengthen our muscles. Secondly, we had better go to bed earlier and get up earlier. Thirdly, we should eat healthy food.

In a word, we should on one hand study hard, and on the other hand, pay attention to our health.
