The training time of personal fitness instructors is about 1-3 months. If you want to engage in the fitness industry, you must systematically study the course content and practical skills required by fitness coaches and obtain certificates. Generally, I go to the fitness instructor training school to study, and then take the exam organized by the school. After passing the exam, you can get a fitness instructor qualification certificate. Fitness instructor's salary is basic salary+sales commission+class commission (course unit price * class hours * class commission)+bonus. Fitness instructor's salary is quite good. Set up national fitness training, Victoria's secret slimming training, sports injury training and other professional fitness courses.
