Fitness instructor assistants have been recruiting people, because there are two kinds of gym instructors in China, personal fitness instructors and fitness instructor assistants. Under normal circumstances, personal education is full-time, and fitness instructor assistants are mainly part-time. Fitness instructor assistants are more common, such as cycling instructors, yoga instructors, aerobics instructors and so on! The functions of private education include muscle gain, fat loss, exercise rehabilitation, stretching and so on. At present, there is a shortage of fitness coaches and assistants in the industry. The reason is very sad, and there are very few newcomers to learn the questions.
