The concept of "sports" is a scientific concept, which needs to match the physical quality of individuals. If you are a healthy guy in your twenties and thirties, it's really good "exercise" to take 20,000 steps of dao2 every day. If you are 5 or 60 years old, or you are still young, but you have some diseases, then it is not recommended to exercise so forcibly. Especially for the elderly, walking 5 1000 steps every day is usually a lot of exercise.
Some people are in good health, and it is natural to keep exercising for a long time and walk more than 20,000 steps every day. Some people like sports. They can't sit still and run around all day. And some people, introverted, sit there for a long time and don't like sports. Even if you exercise, you can't stick to it.
