Kkeokgi(Joint-Lock)

Kkeokgi (joint-lock) includes a set of techniques of restraining by using the principle of levering, pressing, or twisting and pulling out the hand from the opponent’s grasp by the Makgi (blocking) technique; thus, many things can be applied to Joint-Lock. Kkeokgi (joint-lock) should be performed swiftly without preliminary motions, and while ensuring that the motions are not excessively large. The trainee should use the opponent’s balance and direction of force to their advantage. Additionally, the trainee should use the body’s elasticity (rotational force generated from the twisting of the waist and ground reaction force) to perform Ditgi (stepping) and Kkeokgi (joint-lock) simultaneously. To control the direction of the opponent’s hand, the position of the gripping hand should be close to the joint of the opponent’s arm. The trainee should quickly find their center of gravity after the movement.

The types of Kkeokgi (joint-lock) include Biteureokkeokgi (inward twist joint lock, outward twist joint lock), Nulleokkeokgi (press joint lock), Georeokkeokgi (tripping joint lock) and Songarakkkeokgi (finger joint-lock).
