At present, there are two ways to obtain the certificate of fitness instructor in China. One is to register for the exam in the State Sports General Administration, and the other is to participate in the training of fitness instructors. This training institution can generally issue certificates of fitness instructors. The former needs certain fitness professional knowledge, and the general on-the-job fitness instructor exam is more suitable. Some of the following training applications need foundation, and some can apply for zero foundation, so choose the applicant according to your own situation. At present, fitness instructors don't need to have a high degree or above junior high school, but there is absolutely no harm in having a high degree. It is an essential difference whether you can't keep up with school or not. At present, the fitness qualification certificate is not very important in China, but it depends on your own conditions. You can go to school and exercise now, without delay. When you grow up, you should go to the gym as a part-time coach. At least you have to graduate from college and do this for your career.
