Hello, the questions answered on the first floor can be found online. What we want is the experience summarized by our predecessors. I am also a physical education student who practices 1500m. I eat an egg every morning, drink a bottle of milk, eat some usual meals and eat more meat at noon, so that I can have enough physical strength when I train in the afternoon. After the afternoon training, my legs will be sore because I am too tired. In training, when running laps, the quantity should go up and the intensity should go up. {You have to run 35 laps in the morning, test your performance in the afternoon (on the 400-meter playground), run at variable speed, run eight 600-meter sprints, run five at full speed 1000 meters and run four at 2000 meters, so that your exercise can reach the first-class level} Only in this way can you improve your performance as quickly as running water. This is what I do. . . I hope I can help you, and I wish you better and better sports performance. . . . .
