As night fell, the cute and naughty stars came out one after another. The night was originally so beautiful, but for me, it was so terrible. "You can do sit-ups now." My mother's lion roar came again. I climbed onto the bed very reluctantly and started to practice sit-ups. I did them quickly at first. At the beginning, it was like a wild horse running away from its reins. I did them quickly, but I couldn't hold on after doing more than 20. Then, I started to do them slowly. When I did more than 20, I accelerated vigorously, but my physical strength obviously couldn't keep up. I was still unwilling to give up. I decided to do it at a constant speed. Sure enough, this was both labor-saving and fast, and it was not difficult to do it. I rushed through the 30 mark in one go. In the physical test, I successfully exceeded 40 and achieved excellent results!
