Fitness instructors are really popular. You can go to some regular schools to take the coach's certificate, but it is recommended not to delay the courses of college students.

A regular school that takes a coach's license will give you the physical strength and knowledge in books, so that you can get a coach's license better, easier and faster.

But as a fitness instructor, you also need to have a strong body, so you also need to spend some time and energy on fitness to make your body perfect.
