I see that most people who get up early to exercise are old people. Because the old man sleeps less, he wakes up early. By six or seven o'clock, you can already start exercising.

Young people work hard, work or study and can't sleep. Students are ok, but it is more difficult for adults to exercise at school.

In this case, if you can get up early and keep exercising, it is really commendable and I admire it. This is a super self-discipline and firm belief.
