The seogi (stance) means keeping any part of the body except the two feet not touching the ground or the floor, using the lower part of the body. The upper part of the body including the arms can make free motions, but the trunk should be kept always erect. The seogi techniques give great influences over the movement of the center of gravity and the center of weight, and there are various seogi techniques according to the positions and movements of two legs. Sometimes a ponderous posture makes the seogi technique ready for defense, and at times an unstabilized seogi makes the movement of the center speedy and exerts impulsive forces so that one may be ready to take next actions swiftly. The types of seogi are classified according to the position of feet, either widened apart side by side or fore and back and according to the way of keeping the knee, either stretched or inflected.
If the feet drawn close, the center of the body becomes unstable and the center of gravity goes higher, making the stance insecure, if the knees are stretched. Therefore, the wide open feet and the inflected knees make a balanced solid stance, which in turn lacks speedy movements of the center of the body as well as powerful impulsive force.
As mentioned above, the maintenance of balance is largely influenced by the width between two feet. Persons have different feet from one another; therefore, a balanced stance cannot be uniform among individuals. Usually, the unit of a stride or step is used to measure the breadth between the feet in a fore and back stance, while the unit of a sole length (e. g., one foot or two feet) can be also used for measurement in making a stance and the direction of eyes or the body will be the base line of an angle.
We will divide the stances into three categories, Neolpyo seogi (open stances), Moa seogi (close stances) and Teuksu Poom seogi (special poom stance)..
This is the attention position used before and after class and it is the first stance learned in Taekwondo.
The feet are at 45 degrees. However, recent Kukkiwon changes now require feet to be touching and pointing forward, particularly in WTF recognized sporting events. Failure to do so results in point deduction during a competition.
The upper body, waist, and knees are straight. Shoulders are relaxed, the chin is pulled in, eyes looking forward, and the feet are spread one shoulder width apart with the toes pointing straight forward. this stance is the starting point for all movements.
The feet are one and a shoulder width apart. Both knees bent and perpendicular with the ankle. Push the chest slightly forward. Have both fists at waist level with wrists facing upward. The point of balance is between the feet.
This is used in offense and defense, moving aside during the opponent's attacks.
This stance makes it easy to push forward, thereby enabling one to perform attack techniques.
