Insist on running and fitness every week, with low resistance and not easy to get sick!

Running can improve your resistance, but how long it takes to see the effect is related to a habit you stick to. Only by forming such a habit will your body gradually become healthy. After all, running is a delicate sport. Some people are in poor health, but sometimes there are many chronic diseases that cannot be treated with drugs at all, and can only be improved slowly by improving their resistance.
