At first, the national post certificate can only be tested at the primary level. After taking the primary exam, you can only apply for the intermediate exam after working for two years, and the advanced exam is four years. Bachelor degree or above, who studies sports and fitness, can directly apply for the intermediate level. The certificate of China post is not difficult to test. How long does it take for people with zero foundation to take the national post exam? But if you expect to get the certificate of national post, you can become a coach. I don't recommend doing this. Nowadays, people's awareness of fitness in society is gradually increasing, and people who can only use equipment can't survive in the fitness industry.
If you want to develop well, don't just look at national certificates. The certificates with high gold content outside are the four major international certifications. After becoming a personal trainer, you have to take an international certification.
If you want to take the national exam, go to 567 Go, where the training is still very good.
