National fitness refers to the ability of all people, regardless of gender, age and age, to enhance the strength, flexibility, endurance, coordination and control of all parts of the body, so as to make the people strong. The aim is to improve the national physique and health level in an all-round way, focusing on teenagers and children, and advocate that the whole people participate in physical fitness activities more than once a day, learn more than two fitness methods, and conduct physical fitness tests once a year. In order to commemorate the success of the Beijing Olympic Games, the State Council approved to designate August 8th of each year as "National Fitness Day" from 2009.
