Oom Yung Doe schools offer training in 8 complete martial arts, including Kong Su (Tae Kwon Do). The video below shows Kong Su demonstrations, starting at 1:52.
The focus is on linear speed and snap. Defenses are straight up, down, in, out, and side. Offense is straight, side, back, and forward. The feet (especially front snap, side and reverse kicks) are more often used than the hands. The form is hard. The strikes are usually straight, and in all different angles.
Oom Yung Doe uses Kong Su as part of its basic training. The movements are simple and linear, providing a basic, but necessary foundation of speed, strength, and coordination before learning more advanced and intricate martial arts techniques. Kong Su movements are very beneficial for younger students for building reflexes, coordination, and timing. It is recommended for students over 50 years old to practice these movement lightly without snap as it can be overly stressful on the joints.
