As we all know, good health is very important to the success of the exam, so I am writing to tell you how to strengthen your physique. Recently, most students are under great pressure, which makes it difficult for them to survive. As far as I am concerned, first of all, students should go to bed early and get up early. Only in this way can you keep enough sleep. Secondly, you need to pay attention to a balanced diet. In other words, you should eat less junk food. Besides, you should do more exercise. Finally, I think everyone needs to enhance their health awareness.
