There is no age requirement for fitness instructors. Fitness instructors are professional and skilled talents, and they can be engaged in fitness coaching at all ages.

There are many fitness members aged 30-50, and they have a better sense of identity and trust in professional coaches of the same age.

Our college has students over the age of 30 studying at school every period, and the income from graduation work is more than 10 thousand

So your age is fine, and it won't affect your employment.
