According to your own situation, 3-5 days a week is more appropriate. If there is more, there will be a burden, and if there is less, there will be no such good effect. If it is aerobic exercise, exercise continuously for at least 45 minutes at a time. Only at this time will it be effective.

Extended data:

Running is defined as land animals moving with their feet. It is defined as a step in sports, and both feet will not land at the same time. It can also be aerobic exercise or anaerobic exercise.

The best time for running is from 9 am to 10, and from 4 pm to 6 pm. The former has fresh air and the level of adrenocortical hormone in the body reaches the peak. According to the biological clock, the body's adaptability and physical mobilization are at their best from 4 o'clock to 6 o'clock.

According to experts, if you are not careful, running may cause damage to some parts of the human body. For example, the ankle, if the ankle muscles are not developed enough and the landing position of the foot is not correct, it will be difficult to support for a long time when running.

For amateur runners, it is the most common posture that the heel falls naturally when running. Over time, it will increase foot friction and even cause injury. So you can buy a pair of running shoes with heel cushion to reduce the friction between heel and ground. In the long run, gradually adapting to the landing of the sole of the foot and strengthening the buffer between the joint and the ground can maximize the protection from injury during running.
