Exercise makes the circulation of qi well, but when the flow of qi is too strong, sometimes the body cannot absorb it. This is the situation that the body is filled with heat, and one notices it as a pain, for example, one has a knee pain when having walked too much, and an elbow pain when having played tennis too much. Sometimes, one experiences a chest pain.
It is important to know the condition of the body when exercising, and make sure how long you can do it. Please think to what extent you start feeling the pain, and how you can avoid the pain.
