As an experienced person, I don't think so. First, I practiced by myself, and my knee was injured with effusion, so I found a private teacher to practice seriously. After practicing for this period of time, I found that posture standards are very important when exercising. The position of the force is wrong, the action is not standard, and it is easy to get hurt. It is easy to form permanent damage after a long time. Taobao just makes an exercise plan for you. As a fitness girl, it is too easy to go wrong without a coach to guide and supervise the specific operation. So ... yeah.
