Neigong

The martial art school of neigong emphasises training the coordination of the individual's body with the breath, known as "the harmonisation of the inner and outer energy (內外合一)", creating a basis for a particular school's method of balancing the mind and body for optimal health and effective utilisation of coordination of intention and power for effective technique.

Neigong exercises that are part of the neijia tradition involve cultivating physical stillness and or conscious (deliberate) movement, designed to produce relaxation or releasing of muscular tension combined with special breathing techniques such as the "tortoise" or "reverse" methods. The fundamental purpose of this process is to develop a high level of coordination, concentration and technical skill that is known in the martial arts world as neijin (內勁). The ultimate purpose of this practice is for the individual to become at one with heaven or the Dao (天人合一). As Zhuang Zhou stated, "Heaven, earth and I are born of one, and I am at one with all that exists (天地與我並生, 萬物與我唯一)".

Martial neigong is about developing internal power. One way to possibly achieve this is to train particular exercises regularly where the breath is matched with movements of blood or to effect the movement of blood throughout the body. Through these exercises it can be possible to move the blood to a particular area during a particular movement to have a particular result. One of the benefits of martial neigong exercises is the relaxation of blood vessels, nerves, muscles and sinews to help the body move more freely. With the body moving freely and an excess of blood moving to a particular area with little or no effort, the practitioner can possibly develop many benefits. These benefits may include:

• faster recovery from injury to the hands
• an ability to hit with more force
• an ability to move faster (speed is crucial in martial arts)
• the health benefits of being relaxed
• an increase in connection to your legs, spine, arms and head
• increased stamina
• increased athletic ability and health
• regulation of blood pressure
• actually experiencing the channels of the body as they truly are, which can possibly be different from the books
• developing an authentic dantian that is consciously nourished and deliberately formed which is not defined in the books
• greater sensitivity for sparring and fighting

Wuxia and xianxia fiction often portray the training of neigong as giving practitioners superhuman powers. For example, one may use qi to attack opponents without physical contact, fly with qinggong, or harden the body to resist weapon attacks. These can be seen in novels by Jin Yong and Gu Long, films such as Crouching Tiger, Hidden Dragon, Shaolin Soccer and Kung Fu Hustle, as well as video games such as The Legend of Sword and Fairy and Xuan-Yuan Sword.
