I remember one time, I went in the morning and found there were 10 teenagers, 20 old people and 20 young people here, and the number was countless. I exercise like this: first hold the handle, then run slowly, and run faster and faster. I am very interested in this. After repeated drills,
I'm very, very hurt. 10 I can hold on for a few minutes. But some people can only last for two or three minutes. I go to exercise every day, and my running performance gradually rises, and I am praised by others again and again.
