Today, I met a girl riding a spinning bike. I guess she is a novice. After thinking about equipment for a long time, she rode hard beside me. I guess my sister didn't have confidence and thought it was riding a bike. After riding for more than 20 minutes, she did her best. After riding, my sister came down and stumbled. I felt normal at that time, and I couldn't ride it myself. As a result, I watched my sister go out like this and fell flat, that's all. Several of our big men rushed to help. Finally, fortunately, the coaches are here and the sister is safe and sound. I advise all brothers and friends to exercise moderately. Last time I saw someone doing leg exercises in Weibo, I was directly cut down. Although fitness is good, don't be greedy.
