The natural advantage of female sales is that she has a high chance of success by making an appointment with members in the early stage, talking about orders and continuing to attend classes in the later stage. Basically, after a period of time, female fitness instructors will have a full schedule of classes every day, and some even can schedule 7 or 8 classes a day (this is really hard for girls! ), which is why the salary of female coaches is generally much higher than that of male coaches.
