It is reported that the health of young people in China, college students in particular, is not as good as is supposed to be. There are many reasons for this fact, but the main reason is that many people ignore the importance of physical exercises.

First, physical exercises can improve blood circulation, speeding up the supply of nutrients and oxygen to every part of the body and the removal of waste from the blood through sweating and exhalation. Secondly, physical exercises can promote a healthy metabolism. It helps with the digestion and absorption of food, thus giving everyone a good appetite. Thirdly, physical exercise can help consume excessive fat in the body, preventing people from putting on too much weight, thus keeping them in good shape.

In conclusion, physical exercises not only keep us fit and strong, but also help us to be successful in our lives. It is, therefore, strongly suggested that young people spare some time to take an active part in various kinds of physical exercises.
