Be good at learning by social interaction and tools. Socialization means taking the initiative to consult someone with obvious training foundation in the gym. These people are also members. They don't have to pay for the advice. The problem they faced at first was that many people didn't speak when consulting others. The tool is to make good use of the video camera of the intelligent terminal and the post-it note recording function to record all the actions you practice and the scheme you use, and ask experienced people for help to correct the action problems. Recording one's actions for guidance is something unimaginable more than ten years ago, and now it can be realized anytime and anywhere. However, if you ask someone for help, do you want to give it a fee? If so, how much is better? It is human to help others, and it is duty not to help. Because they are incompetent, it is impossible to refuse. After all, if you really hurt yourself, it is impossible for others to bear joint and several liability.
