The traditional fitness instructor training class needs at least offline study. Do you need to take the fitness instructor certificate? The cost of two or three months is before 20,000 or 30,000. One is the course fee, research fee, living expenses during the study period and so on. It is a bit expensive for people who want to transform the fitness industry, and the entry cost is too high and the burden is too heavy. Therefore, I choose the online training courses for stars, aviation and Taoism, which cost more than 3,000 yuan. I use my mobile phone to study and research at home, and the knowledge I have learned is the same as certificates and courses. There is no need to spend tens of thousands of dollars to get a license.
