Yeah I've finished all that stuff (lies)
Hmm....this is very tiring but I'll try....
Taijutsu is basically Hand to Hand combat. Its composed of several disciplines and arts, the most used of which is called Strong Fist. Other types include for example, Gentle Fist. Taijutsu uses the body as a weapon to attack or defend against your enemy. Its powered by chakra but in a different way than Ninjutsu or Genjutsu, as you don't need to mold chakra to perform Taijutsu (as seen in
Rock Lee's case). Chakra in Taijutsu acts as the fuel, powering the body through its moves, specially in terms of
Physical energy. The main characteristic of Taijutsu is that
it can be combined with several other areas of a ninja's arsenal, such as Kenjutsu or Ninjutsu (in this case producing Nintaijutsu). This makes Taijutsu the basic skill every ninja has to have. Taijutsu can be advanced
through mastery of the Eigh Inner Gates. These are "limiters" that exist within the chakra circulatory system and that regulate and limit the
chakra output, keeping it at safe levels, thus keeping the body safe. Through intense training and skill, a ninja can unlock them gaining access to increased chakra output and, through that, increased physical power.
However, doing so damages the body and may even lead to death.
Hope that's enough.....you made me sweat already
