Girls do well in fitness coaches. Generally, I go to the fitness instructor training school and then take the exam organized by the school. After passing the exam, you can get the professional qualification certificate of fitness instructor. 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.
