Nèi jìng is developed by using nèigōng, or "internal exercises," as opposed to wài gōng, "external exercises."  

Nèijiā is a broad term used mistakenly in the West as a synonym for the more specific Wǔdāngquán styles, named for their association with the Taoist monasteries of  Wudangshan range, Hubei Province in Chinese popular legend. These styles are enumerated by  Sun Lutang as Tàijíquán, Xíngyìquán and Bāguàzhǎng, but must also include Bājíquán and the legendary Wudang Sword.  Some other Chinese arts, not in the Wudangquan group, such as Liuhebafa, Bak Mei Pai, Bok Foo Pai and Yiquan are frequently classified (or classify themselves) as "internal".
