Charyok is a traditional Korean martial art whose name means "borrowed force"; it was a very popular martial art in early Korea. This art was created by the sonying (a group of Korean mountain people) and is intended for those that are well-adapted and able bodied men. Charyok's techniques and movements include punching, joint breaking and throws based on applying pressure to the "pain centers" of the body. Furthermore, Charyok is also characterized by a lot of head, knee, shoulder, elbow, and foot strikes, some of which can be executed from a sitting position.

Its counter-attacks are mostly based on catching an attack and then pulling in and destroying the attacking limb. Charyok's movements are done in a way in which arms and legs work together and help one another. It also has methods of defence against different animals - for example, against a wolf, bull, bear, or tiger.
