Of course, a fitness instructor is a technical profession, not a teenager. As long as you have enough professional knowledge and skills, you can make a scientific fitness plan for the fitness crowd, solve all kinds of problems they encounter in fitness, and achieve the fitness effect they want to achieve, you can develop for a long time!

The older you get, the more experienced you are and the more trustworthy you are. So when you have enough professional knowledge and experience, you can do it for a long time!
