The language is simple, generous and friendly, which makes the guests feel that you are very powerful and willing to help them realize their ideals or wishes. Remember to smile and infect them with your personality charm. In fact, to be honest, anyone who can be a fitness instructor must have some skills, but why is the effect of teaching guests different? The difference is that some people can speak, and the Northeast dialect can only "fool". Language is infectious, and everyone believes that you can practice with you. Give it time and it will be effective.
