Should I hire a coach to exercise in the gym?

At first, I suggested buying several basic courses on equipment use and planning. This is necessary, because at the beginning, you don't know much about some equipment in the gym, and you don't know what the correct method is. If the method is used correctly, it can greatly improve the efficiency of exercise. If you use it wrong, it will hurt you, not good for your health, but bad for you. So you have to pay 300 to 500 yuan for a basic private education course, and he can teach you all the other correct methods and how to do it.
