First of all, it's easy to hurt your knee. After all, running puts more pressure on your knees than walking. If you don't master it well, it's easy to hurt your knee. Although some people say that it is a running posture problem, it is an imbalance between the left and right, and the sole of the foot falls in the wrong direction. Maybe these are all one reason, but there is another reason because there is not enough running and the body has no adaptive feedback. This situation is often five kilometers, ten kilometers and twenty kilometers. With the increase of running, the knee will gradually adapt, and it will not hurt after a little rest.
The sole of your foot hurts again, but it will hurt again anyway. Especially after running the next day, my feet will hurt when I walk. This is because it is difficult to feel the soles of the feet when stretching, not because of massage relaxation. At this time, you need to step on the ladder barefoot. If it hurts, it will soon be fine. Of course, there are many people who press by hand, but many times they can't.
There is also the urine will become deeper after running, which will happen after long-term upper body exercise, which will seriously lead to muscle atrophy, so running needs a moderate amount. I remember the first time I ran 16 km, my urine almost turned soy sauce. Although drinking water to supplement salt soon, it basically returned to normal after one day. Remember, I also climbed Mount Tai, completely from the Red Gate and under the Red Gate. It takes three hours to get up and two hours to get down. When I came down, I almost ran down the path by the stairs. Then the urine turns soy sauce. Just have a rest and drink some water. However, this situation depends on the physical condition of the individual. If it is serious, you should go to the hospital for medical treatment, especially when you have internal pain.
Finally, the disadvantage of running is that it won't reduce your stomach. To lose weight, just running is not enough. Running mainly exercises cardiopulmonary function and limbs. Stretch your limbs in time after running. If you don't stretch it, it will become a radish leg. But the effect on the stomach is not great. A fat colleague of the same age said, how did you lose weight after running for so many years? I looked at it and said that at least I didn't see my bulging belly and swimming ring until I put on my T-shirt and shirt. Standing on the podium is very stylish. However, running can't make you have a single action, and even the equipment for training six abdominal muscles, abdominal muscles and other muscle groups can't achieve the effect of bodybuilding.
These are some disadvantages of running. If you need to run, run well, and the shortcomings can still be solved.
Careful stretching before and after running, paying attention to posture, monitoring physical changes, and comprehensively exercising core muscles combined with swimming, equipment and fitness are helpful to improve running performance.
