Fitness instructors are divided into many grades, and those who visit the gym are relatively low-level. People who haven't exercised in the gym are mostly knowledgeable and have relatively low wages. Generally, leaflets are distributed to attract customers to earn some commission.

Regular gym instructors are required to have grade certificates. The technical titles of fitness coaches are divided into three levels: three-level fitness coach, two-level fitness coach, one-level fitness coach and national fitness coach.

There seems to be a personal fitness instructor certificate. If you work as a personal trainer in the gym, you will get better treatment and earn class fees, because you need to do some fitness programs, physical function tests and so on. And you need to use some professional knowledge.

If you want to do related work in the future, I hope you can get a better salary. It is suggested to consult the conditions of professional examinations and make a living sign after practicing yourself. I hope you can become a gold medal personal trainer in the future.
