Reason: Why does our country advocate nationwide fitness? There are many reasons. After successfully hosting the Olympic Games, the development of sports has become more and more important. This is why our country should carry out the national fitness program.

Significance: The significance of advocating national fitness is far-reaching. As long as we look back at our history, before the birth of New China, we were looked down upon because of our poor health. Therefore, the implementation of the National Fitness Program marks that China has become stronger since then. If the founding of the new China marks the people of China stand up.

How: In my opinion, we should first raise the public's awareness of exercise. Then we should provide this kind of exercise opportunity. For example, we can build new sports facilities and organize amateur or professional training courses.
