General exercise is divided into aerobic exercise and anaerobic exercise. If the two exercises are combined, it may be easier to achieve the target effect. It is accepted by many people to do anaerobic exercise first and then aerobic exercise. The reason is that we need to use the most vigorous energy to deal with the most strenuous exercise, so that the exercise effect can be the best.

If you want to do some exercises that don't hurt your knees, you can take a walk or a brisk walk, or you can exercise by skipping rope. But if you love jogging and don't want to hurt your knees, you can wear knee pads. It is recommended to do some joint preparation activities before running, and it is recommended to knead and relax the leg muscles after running.
