I have seen Liu Fang's fitness class in Tik Tok. Since it is called a fitness class, it can improve people's image and temperament. However, if you want to lose weight, it is unlikely to lose weight through Liu Fang's actions, because fat reduction must train muscle strength, not just practice. If you have a better figure, it will be more effective to train Liu Fang. If you are overweight, you want to pass.
