It's just business, just like when you go for a free physical examination or see a doctor, the doctor tells you that there is something wrong here and there, and makes you pay for exercise in their way in a sarcastic way.

However, you have time to go to the gym to exercise, don't you have time to plan your own exercise? The so-called gyms and fitness instructors are just some products of the times. They will only dig holes for you to increase nutrition and pay on time.

If you want to keep fit, it's right to go to the gym. If you just want to recover your physical fitness or health, there is absolutely no need to enter such a place. Proper exercise and health preservation are the perfect standards for urban white-collar workers.
