People always simply think that running is a very simple and convenient exercise, which can be carried out without any measures and protective tools. In fact, this kind of cognition is very one-sided and wrong. You should know that if the running posture is incorrect or the shoes under your feet are not suitable, it will do us great harm, and sometimes the harm to our feet, legs and even lumbar vertebrae is irreversible.
Correct running knowledge should be achieved first, chest out and back straight, and then the natural swing of the arm is that the thigh drives the calf to run forward, not the calf. Remember not to follow the ground with your feet, but to touch the ground with the soles of your feet, so that you can run lighter and lighter, and you won't hurt your body and joints because of the reaction of the ground. Many people feel that their bodies are getting heavier and heavier when running. Actually, it's because their running posture is incorrect. Many people have this wrong feeling because their feet are too strong to react. It is also possible that our bodies are weak because of long-term physical inactivity.
Many people don't breathe when running. You know, running is to match our breathing. If we don't pay attention to our breathing when running, we will probably hold our breath, because we don't breathe correctly when running, which will make our right rib feel dull pain. This is because we don't pay attention to breathing when running.
