It is possible to become a fitness instructor without exercise, not because the standards of the fitness industry are low, but because it is difficult for people who have not exercised to become fitness instructors, because people who have not exercised have relatively insufficient understanding of sports and their own sports level is generally not very high, so it takes more efforts to become fitness instructors than those who often participate in sports.
People who have never exercised and want to be fitness instructors can go to special training institutions to participate in training. People can strengthen their physique and learn more fitness knowledge through training, which is what a fitness coach must do.
