When a fitness instructor is old, he can take a professional route in the process of getting old and do training later. Or take the management route in the process of work. If you are an old practitioner in the fitness industry, then you should be able to do all the industries and management related to the fitness industry. But first, you should have a good major and learn about the training of air fitness instructors. I hope I can help you, and I hope to adopt it! ! !
