What are the most wonderful fitness methods you have ever seen?

It's time to play the horizontal bar first. Because when I was young, I once went to the park to exercise, and a very wretched old man came up to me in front of the horizontal bar in leg press, holding the horizontal bar in both hands and making a circle. The image of that self-righteous strange uncle makes me feel queasy until now, and this fancy horizontal bar action is equivalent to obscenity in my heart from now on.
