First, practice better than students. If you haven't practiced as well as the students below, you will definitely get stage fright. Fortunately, this is easy to do. There are basically no good students in general courses, because good students will not come to a novice coach's class. As long as you practice hard, the teaching of primary school classes will be completely sufficient.
Second, we should have enough experience. Beginners are naturally inexperienced, which depends on the teacher's skill. The level of teachers lies not only in the level of practice or teaching, but also in their rich experience and knowledge. Naturally, it is better to impart these experiences to students and let them have some "experience", which is much better than nothing, although it is not as good as personal experience. Therefore, "a master makes a great apprentice" makes sense. Having a good teacher in the door can save many years of struggle.
Third, theoretical knowledge should be solid. You should know what you have learned and what principles you have taught. Why is teaching different from others? Why is this school different from that one? What kind of exercises does this student need and what kind of exercises does that student need? All the students' doubts can be answered here, and you will naturally be respected. Your field control ability will be improved without improvement. If you don't know anything, let students falter or talk nonsense when asking questions, and students won't respect you, then your class will be out of control. Play the piano, learn ballet, practice martial arts, etc. It takes eight years and ten years to make some achievements. Why does yoga take two or three months? Learn step by step. It's good to take basic courses for two or three months and teach inexperienced students. If a newcomer who has just left his post is facing a student with several years of practical experience, why should he control the field? You should learn from students and ask for their opinions. A novice is a novice. Only by accepting this reality can we make progress step by step and achieve something. Because opportunistic people can't last two years, after two years, the overwhelming advantage of those coaches who study hard begins to appear.
