Taijutsu

Taijutsu is a basic form of jutsu that generally speaking requires no chakra, but chakra may be used to enhance techniques. Taijutsu generally require no hand seals to perform and are much quicker to use than ninjutsu or genjutsu. Taijutsu is simply put, hand-to-hand combat.

Although it is used by nearly all ninja, Rock Lee and his teacher Might Guy use taijutsu almost exclusively, and are experts on many taijutsu techniques.
