Chi Kung

Qigong, chi kung, or chi gung (simplified Chinese: 气功; traditional Chinese: 氣功;pinyin: qìgōng; Wade–Giles: chi⁴ gong¹; literally "Life Energy Cultivation") is a practice of aligning breath, movement, and awareness for exercise, healing, and meditation. With roots in Chinese medicine, martial arts, and philosophy, qigong is traditionally viewed as a practice to cultivate and balance qi (chi) or what has been translated as "intrinsic life energy". It is generally accepted that Qigong exercises have three components: a posture (whether moving or stationary) 調身, breathing techniques 調息, and mental focus on guiding qi through the body 調心. The prerequisite is a calm relaxing state of mind. Qigong is now practiced throughout China and worldwide, and is considered by some to be exercise, and by others to be a type of alternative medicine or meditative practice. From a philosophical perspective qigong is believed to help develop human potential, allow access to higher realms of awareness, and awaken one's "true nature". 

Possible health benefits of qigong have been studied in various medical conditions. Evidence of effectiveness is inconclusive due to the poor quality of the clinical trials.
