People who need fitness usually don't have professional knowledge and skills, so blind exercise can easily go astray, can't achieve their goals well, and even do harm to their bodies. Therefore, the existence of fitness coaches has become a necessity. However, it is impossible for traditional fitness instructors to be familiar with the physical condition of each member. They can only follow the experience, try to ensure that members take fewer detours and exercise safely. The appearance of personal trainers has avoided these embarrassment.
Now the emergence of fitness time has made personal trainers civilian, and they are no longer exclusive to artists and rich people.
