Coaches need to learn a lot, including the movements of practice, the arrangement of courses, the arrangement of dances, the creation of classroom atmosphere, the selection and mastery of music, basic nutrition knowledge, the basic structure of the body, and the handling of emergencies. So it is almost impossible to master the coaching course completely in such a short time. As a coach, you can not only dance, but also teach, pass on your thoughts, give your emotional contagion to members, let members feel your happiness and let everyone feel the fun of sports, so as to win.
