You can apply for training directly through the fitness instructor certificate certification institution. This kind of training is suitable for experienced in-service coaches. Because the requirements of the early fitness industry are relatively low, many old coaches without certificates need to take a certificate to prove their professional level. They have rich experience, teaching methods and professional fitness level. After research, they can go to this institution that specializes in certificate training for a period of time. If you are a zero-based student, it is still very difficult to sign up for the exam directly. I suggest you go to the training school of professional fitness instructors for systematic training. There is also a physical education college student. Under normal circumstances, schools will arrange exams, but this way is also in cooperation with training schools.
