First of all, we say that the main learning object of fitness coaches is people. If your education is above junior high school, then the knowledge of fitness instructors can be learned completely.
As long as we have enough patience, the job of fitness instructor requires us to learn solid theoretical knowledge and more practical skills. When we become fitness instructors after graduation, most of us use theoretical knowledge to help our members solve their fitness problems, so sometimes even if we are knowledgeable, we can't solve their problems better without professional skills and practical experience.
Therefore, no matter your education level is high or low, as long as you keep working hard and keep exercising, you must believe that you can really become a real professional fitness instructor!
