I want to find a fitness instructor and a good training college. Generally, it can be selected according to teaching mode, teaching staff, teaching environment, curriculum, employment and so on. Fitness instructor examination includes theoretical examination and practical examination. Theoretical knowledge includes: sports nutrition, sports anatomy, sports physiology, sports psychology, sports biomechanics, health and fitness, and professional ethics of health coaches.
