2.) 합기도 Hap Ki Do / Ai Ki Do (Korean Style/Japanese Style)

In Hap Ki Do, movements are hard and soft. Target areas are the joints, pressure points, and nerves. Close proximity to the opponent is most beneficial. Hands and feet are equally used in offensive and defensive movements. Strikes are in all directions, and are mostly angles rather than circles. Similarly, in Ai Ki Do, movements are hard and soft, and the target areas are the joints, pressure points, and nerves. However, hands are usually used more than feet. Offensive and defensive movements are applied in all different directions, angles and curves, and a very strong handgrip is used.

What you have achieved is shown by your ability. Your actual ability represents your true condition. Your condition determines the quality of your life, how much your life has improved.

Throughout history Traditional Moo Doe, true martial arts, has constantly been the target of jealousy and rumors – “The higher the mountain, the stronger the wind”. Traditional Moo Doe has always followed the time proven principle – judge based on what you see. Traditional masters and grandmasters have dedicated their lives to preserve the strength of Traditional Moo Doe. Any martial arts school that has true ability does not have to talk about how good they are, they can show it. Some are swayed by what they hear. Foolishly, they lose their chance to change their condition and improve their life. Remember, life is only once. Do not waste your life.
