At present, the national service certificate is a certificate with high gold content in the fitness industry certificate type. Issued by the State Sports General Administration, the scope of industry recognition is relatively high. As a fitness coach, the post qualification certificate exists, and the fitness coach will try to get it. However, you can be a fitness instructor without taking the national service certificate, but the gold content of other certificates is not as high as that of the national service certificate, and they are generally obtained in fitness colleges.
