Chigong refers to any number of movement sets or standing postures which serve as both physical exercise and meditation. They can be strictly health related or an integral part of Chinese martial arts (neiggng) as seen most notably in Taijiquan (tai chi), and Baguazhang, and Hsing Yi Chuan.
In Chinese medicine, Chigong circulates and generates Chi energy to the vital organs and channel pathways to increase health and vitality. If acupuncture is akin to fine tuning the body’s circuitry, and herbs are like charging the battery, Chigong would be like increasing the voltage that propels Chi through the body. It is not uncommon to feel parts of the body heat up and extremities start “buzzing” when doing Chigong.
Chigong is both a self practice for health and a system of energy therapy to help others.
