Although the basic salary of the fitness instructor is very low, the commission is very high. The commission of fitness instructors is their main source of income. In addition to the commission of ordinary courses, they also sell a set of courses, accounting for a certain proportion of the total sales of courses.

For coaches with good fitness coaching skills, they are not worried about selling courses, so for them, they never ask, "Is it stable to be a fitness coach?" This kind of problem. However, it is difficult to guarantee those who have no ability to coach, especially those who have not been trained in-service coaches. These are difficult to guarantee stability, because they don't have good coaching skills, and naturally no one will recognize them. Not only is it difficult to maintain its own stability, but it will also have a bad influence on the reputation of the stadium. Only by seeking lessons from the whole world can we maintain this reputation.
