The structure of the body is a graphic expression of our physical, emotional and mental state. It reveals past experiences, present personality and feelings unexpressed.
It stands to reason that when the misuse of our mind actually creates a malfunctioning body, then the proper use of our consciousness can create a harmoniously performing body.
There is a muscle/emotion relationship. When emotion is not expressed or released properly, it will migrate to specific areas. This blocked emotional energy will manifest as muscle soreness.
