I want to go to the gym, but I haven't been there. I can't use those devices. How can I tell them what to say when I go in? Do you need to prepare anything?

It's best to hire a personal trainer. The cost of a class is basically between 300-500 yuan. If you learn some simple basic skills, the fee will be relatively low, while if you choose to learn functional, fat-reducing or advanced skills, the fee of a personal fitness instructor will be relatively high. You can also choose to study fitness instructor training courses and learn fitness professional knowledge in fitness courses. After learning, you can exercise yourself or be a fitness instructor.
