On February 18, 2022, he officially moved his favorite fitness to the live broadcast platform, which set off a national fitness craze. Many people like Liu Genghong's shuttlecock-kicking aerobics because of the moving melody and simple and quick fitness movements in Compendium of Materia Medica, and then he constantly introduces new aerobics again and again, so that many netizens can follow him when they are isolated at home. Even if some people can't persist, they will pick up aerobics again and again with his magical encouragement. Wang Wanfei, as the closest person to Liu Genghong, often complains that Liu Genghong is possessed by fire. Whether living or going out to play, he never forgets the matter of fitness. He will never take a bus when he can walk and never lie down when he can stand. Visiting a friend's house can also persuade others to join the fitness ranks. As the biggest victim around Liu Genghong, Wang Wanfei is full of bitterness, and the basic reason for their few quarrels is sports. However, Liu Genghong does have some fitness brushes. When Jay Chou came up with the album, in order to get in good shape, he specially asked Liu Genghong to help him keep fit. In a short time, he has eight abdominal muscles, which is amazing. Liu Genghong himself didn't explain his wife's complaints too much. In his view, everything he did was for the benefit of Wang Wanfei. You know, Wang Wanfei has some problems after giving birth. Without proper exercise, it is difficult for him to recover. Although he sometimes forces each other, it's because Wang Wanfei is too lazy. If Wang Wanfei is not strict, he will be lazy easily. In his eyes, exercise is a very happy thing. People around him will feel very hard if they don't feel the charm of sports. When they really practice, they will find that exercise is good.
