At present, fitness instructors in the industry generally study for about one to three months. For those who have a fitness foundation, such as sports students and veterans, studying for one month can also become a private education, but the content of the study is relatively incomplete. For most people who want to engage in fitness coaching in the future, whether they are zero-based or experienced, they will mainly study for three months, and learn comprehensive skills and knowledge, and their later work prospects will be better.
