1, explaining fitness knowledge. As fitness coaches, they naturally know much more about fitness than we do, and we should also know some fitness knowledge when exercising, so we need fitness coaches at this time, and they will tell us some professional fitness movements and related points.

2. Correct the mistakes. For some beginners, they don't know much about fitness, so they often make some wrong moves in the process of fitness. At this time, the fitness instructor can help you correct your mistakes and help you correct some wrong views.

3. Make a plan. Some people exercise to lose weight, others exercise to gain muscle, and different fitness methods are needed for different purposes. The job of a fitness coach is to help different people make a plan that can achieve results quickly. And provide you with scientific fitness methods, so that you can avoid detours.

4. Sell fitness cards. Another job of a fitness consultant is to sell you a fitness card. They usually give you two private lessons for free at first. When you are satisfied, they will strike while the iron is hot, tell you the benefits of getting a fitness card, and even give you some big discounts. In fact, this is also a means for them to attract customers. Sometimes they tell you to leave it alone after you get the card. Of course, not all fitness consultants are like this, but some are responsible, so they are doing it.
