One of the many personal achievements Grandmaster "Iron" Kim has reached is the Kyong Gong Sul Bope (flying side kick). Pictured above is Grandmaster jumping from the top of a building. A corner of the roof is visible in the lower right corner of the picture (indicated with a white arrow).

In 1970, Grandmaster "Iron" Kim demonstrated Kyong Gong Sul Bope by jumping from the equivalent of an 11-story building. In 1972 Grandmaster "Iron" Kim again demonstrated the Kyong Gong Sul Bope movement by jumping from the equivalent of an 8-story building, landing without injury on a sloped surface below. Performing the Kyong Gong Sul Bope movement is a phenomenal feat, but more important is the tremendous internal power and strength that an individual must possess in order to demonstrate Kyong Gong Sul Bope. World-wide, over the centuries, only a very small number of people have acheived this ability. This movement is only possible with Traditional Moo Doe Training, otherwise this would be impossible. Grandmaster "Iron" Kim has maintained the amazing mental and physical strength needed to execute this movement. Even now, we have no doubt that Grandmaster "Iron" Kim is still capable of precisely demonstrating the Kyong Gong Sul Bope form. He is a living example of the benefits of achieving phenomenal Moo Doe strength.
