There are usually two ways to obtain the national vocational qualification certificate of fitness instructors: the first way is to register directly in the relevant departments or official website, which is suitable for some on-the-job coaches to apply for the exam, so the registration is generally only for the exam content, and there is no other redundant course learning content. The second type is a training institution authorized by the State Sports General Administration. After systematic training in related majors, certificates can be obtained after completing all professional courses. Students generally study in the fitness college system, and then obtain the professional qualification certificate of fitness instructor. Gansu University generally conducts textual research in Xi 'an.
