Shotokan training is usually divided into three parts: kihon (basics), kata (forms or patterns of moves), and kumite (sparring). Techniques in kihon and kata are characterised by deep, long stances that provide stability, enable powerful movements, and strengthen the legs. Shotokan is regarded as a dynamic martial art as it develops anaerobic, powerful techniques as well as developing speed. Initially strength and power are demonstrated instead of slower, more flowing motions. Those who progress to brown and black belt level develop a much more fluid style that incorporates grappling, throwing and some standing joint locking techniques, which can be found even in basic kata.[6] Kumite (fighting) techniques are practised in the kihon and kata and developed from basic to advanced levels with an opponent.
