Why do some gyms train personal fitness instructors for free and pay a basic salary?
In fact, it is to familiarize you with the environment first, but this kind of private education is always just exercise, which is far from the comprehensive knowledge that private education really needs to master. After all, personal education is not simply to guide exercise, but to bring members a healthy concept of life, so that you will never make progress after staying in this gym for ten years and become his cheap labor forever.
