Personal education can make people who just want to keep fit take fewer detours, and it can also play a role in supervising exercise. Moreover, the coach will point out the power point and standard of each movement, and only the action standard can play the role of exercise. Otherwise, everything will be in vain. Many people, especially girls, don't know much about the use of gym equipment and sports parts. After the private education, the coach will give it to you and go to the gym. You can't just run on the treadmill, you have to sweat and exercise in all directions. But if you have a certain sports foundation and are familiar with the equipment in the gym, you can actually do it without personal training, so it's up to you.
