A man doing cekongfan, a common move in Changquan.The forms within the Long Fist style emphasize fully extended kicks and striking techniques, and by its appearance would be considered a long range fighting system. In some Long Fist styles the motto is that "the best defense is a strong offense," in which case the practitioner launches a pre-emptive attack so aggressive that the opponent doesn't have the opportunity to attack. Long Fist uses large, extended, circular movements to improve overall body mobility in the muscles, tendons, and joints. After advanced study, a Long Fist practitioner will find that its forms contain Qin Na joint-locking techniques, as well as Shuai Jiao throws and takedowns.

The Long Fist style is considered to contain a good balance of hand and foot techniques, but in particular it is renowned for its impressive acrobatic kicks. Of contemporary wǔshù events, Long Fist techniques are most popular and memorable with its whirling, running, leaping, and acrobatics. Chanquan moves are difficult to perform, requiring great flexibility and athleticism(athleticism is someone's fitness and ability to perform well at sports or other physical activities) comparable to gymnasts.

Long Fist's arsenal of kicks covers everything from a basic front toe-kick to a jumping back-kick, from a low sweep to a tornado-kick. Specifically, typical moves in modern Changquan include: xuanfengjiao, xuanzi, cekongfan, and tengkongfeijiao.
