Acu-yoga is a cross between yoga and acupressure that can be used to relieve stress and pain. This type of bodywork is a wonderful self-care technique that anyone can use.
As with other therapies based on ideas in Traditional Chinese Medicine, the concept behind it is that the body contains a life force or life energy. This energy is called qi (chi), ki, or prana. Qi flows through the body on pathways called meridians. When qi is flowing freely through those meridians you are healthy. When qi is blocked along the path of the meridian, you have illness or dysfunction. Acupressure works to unblock qi. Find out more about acupressure.
