Hapkido is a Korean martial art incorporating hand strikes, kicks, and joint manipulation techniques. Hapkido is based upon three principles: Hwa (harmony), Won (circle), and Yu (dynamic) which are incorporated into each technique. A Hapkido practitioner uses these principles to off-balance or break an opponent’s energy. Once an opponent’s energy is broken, a finishing technique is applied. The end result is having the opponent in a restraining or submission hold preventing him from continuing the attack. Hapkido techniques do not rely on physical strength which makes it possible for a smaller person to successfully defend himself/herself against a larger and stronger attacker.
