Taijutsu

Taijutsu (体術; Literally meaning "Body Techniques") is a basic form of  techniques and refers to any techniques involving the martial arts or the optimisation of natural human abilities. Taijutsu is executed by directly accessing the user's physical and mental energies, relying on the stamina and strength gained through training. It typically does not require  chakra, though chakra may be used to enhance its techniques. Taijutsu generally requires no  hand seals to perform, occasionally making use of certain stances or poses, and are far quicker to use than  ninjutsu or  genjutsu. Taijutsu is simply put: hand-to-hand combat.
