I am one of the students in Zhao Jilong WeChat Kung Fu class. I am over 60 years old. I used to have a backache. I dare not do any aerobic exercise. Sometimes it is very difficult to climb stairs. Later, I saw Zhao Jilong WeChat Kung Fu class on TV, and I thought it was good to exercise at home, so I signed up. I didn't expect this course to really help me a lot. First of all, the requirements are not very high, and there is no particularly difficult action. They are all kungfu that can be practiced in daily life, and they have certain practical effects while preserving health. After practicing for less than three months, my family said that my face was much better, and I myself found that the problem of backache had improved. I'm still practicing piling, and I believe the effect will be better later.
