Inner Knee Stance

오금서기 ogum-sogi

Difficulty Level: Advanced Level Technique: Stance ( 서기 sogi )

In Korean martial arts taekwondo, the Inner Knee Stance ( 오금서기 ogum-sogi ) is an advanced stance ( 서기 sogi ) where the practitioner lifts one foot ( 발 bal ) like a crane and places the instep of the foot ( 발등 baldeung ) on the area opposite of the knee called ( 오금 ogum ).

Bend your knees ( 무릎 mureup ) and lower the body like a Horse Riding Stance ( 주춤서기 juchum-sogi ). The supporting foot ( 발 bal ) should be facing forward. The stance ( 서기 sogi ) can be used to step in and attack the opponent with a Spearhand Vertical Thrust ( 편손끝 세워찌르기 pyeonsonkkeut-sewo-jjireugi ) targeting towards the sternum ( 흉골 hyung-gol ), the eyes ( 눈 nun ), and throat ( 목구멍 mokgumeong ) as suitable targets.

The weight distribution is 90% to the standing leg and 10% to the supporting leg. With one leg touching the ground, the supporting leg should maintain 10% weight distribution while placed on the area opposite of the knee called the ( 오금 ogum ) for support and to maintain center of body balance. The practitioner should have a mindset to have overall body balance as 10% instead of 0% on the foot that is placed on the area opposite of the knee called ( 오금 ogum ).

For the stance ( 서기 sogi ) to be effective, the practitioner must have rock solid balance and agility. Balance is an ability to maintain the line of gravity of a body within the base of support with minimal postural sway. Agility or nimbleness is the ability to change the body's position efficiently, and requires the integration of isolated movement skills using a combination of balance, coordination, speed, reflexes, strength, and endurance.

Practitioners must have their body weight correctly distributed during each different stance ( 서기 sogi ) and during footwork ( 딛기 ditgi ). Each technique must be correctly aligned. Every technique must display the requisite speed, power and firmness to be realistically used as an attack or defense move.

Training Methods

How well one improves with training depends on several factors, such as the frequency it is engaged in, and the type of feedback that is available for improvement. If a student does not train often enough, reinforcement fades, and he or she is likely to forget what was learned.

When learning the stance ( 서기 sogi ), it is helpful to use a mirror to observe your stance ( 서기 sogi ) posture and fix your mistakes immediately. Initially, a student may need focused feedback from a certified Master Instructor ( 사범님 sabeomnim ); however, as they progress, they must develop the ability to self-assess the stance ( 서기 sogi ).

Minimum Level Requirement: Black Belt (dan)

Difficulty of Technique

Taekwondo students of geup ranking learn the most basic techniques first, and then move on to more advanced and difficult techniques as they approach 1st Dan Black Belt.

Every technique must display the requisite speed, balance, power and firmness to be realistically used as an attack or defense move.
