There are twelve main meridians and 8 other special meridians within the human body. Meridians are similar to electrical wires or nerves. They run from the top of the head to the tips of the toes and fingers. Each meridian is associated with an internal organ. When there is a lack of energy flow or blockage within the meridians, health problems can arise. Through proper diet, exercises and life style, it is possible to keep the chi (energy or life force) flowing through the meridians. These exercises help to increase this flow in addition to enhancing strength, flexibility, range of motion and balance.
