Attention should be paid to running: "three needs and three good"

"Two musts" means:

First, it takes a certain amount of time, and short-term exercise is hardly effective. The lower limit of each run is 20~30 minutes, and the upper limit is 1~ 1.5 hours. This amount of time does not need to be completed at one time, and can be accumulated in one day.

Second, we must have a certain strength, neither too low nor too high, and it is appropriate to bear it ourselves. Generally speaking, running fast is not as good as jogging. Some old people can't jog, but walking quickly can achieve the effect.
