By the way, 1000 meters, just run more, and the training is usually 3000 each time. In fact, this amount of exercise is not large, and you can get used to it slowly. Just transfer at your own pace and don't be too tired. The best pace is around 180. Remember to pull your legs before and after running. This is very important.
As for pull-ups, this is the most difficult, which has a lot to do with your weight and strength. It is not easy to improve in a short time, but you can plan for a long time and keep fit, mainly exercising arm strength, chest muscle and back strength, doing push-ups, dumbbells, pushing cakes and so on. There are also many gyms, so it is good to do targeted training.
50 meters is just to see your explosive power. Just use your dormitory to rush up.
Height, weight and vital capacity also affect your performance. Being overweight has a great influence on your running, pull-ups and long jump. Therefore, I suggest that you lose weight first if you are overweight, and then you will be specially trained to lose weight. Lung capacity can be improved by running, and swimming practice has the best effect!
As for the standing long jump, jumping more, moving first and then stretching, it is easier to jump further.
