Foot and leg structure
| Body part | Technical requirement |
|---|---|
| Rear foot | Turns 15 degrees inward |
| Front foot | Points 15 degrees inward from the line of attack |
| Rear leg | Carries most of the body weight and provides the main base of support |

How to measure the stance
The length of L-Stance is 1.5 shoulder widths. It is measured from the inner foot-sword of the rear foot to the toes of the front foot. This measurement is important because L-Stance is not measured in the same way as Walking Stance. The reference point begins from the rear foot-sword, not from the rear big toe.
The width is minimal. The front and rear heels should be separated laterally by roughly 1 inch or 2.5 cm. This small lateral separation helps the stance remain narrow while still giving enough structure to avoid placing both feet on exactly the same line.
A common mistake is making the stance too wide because the student wants to feel more stable. This changes the nature of the stance and makes it less efficient for defensive techniques. Another common mistake is making it too short, which reduces the ability to absorb pressure and weakens the line of the body.
Weight distribution
L-Stance uses a 70% and 30% weight distribution. The rear leg carries 70% of the body weight, while the front leg carries 30%. This is one of the defining characteristics of the stance. The body should not be balanced equally between both legs, and it should not lean forward into the front leg.
The heavier rear leg gives the stance its defensive quality. It allows the practitioner to draw the body slightly away from the opponent while keeping the front leg available for fast movement. The lighter front leg can assist with stepping, shifting, blocking, or preparing for a counterattack.
The weight distribution must be controlled without making the posture stiff. The stance should feel grounded through the rear leg, but the body should still be able to move. If the rear leg becomes too heavy or locked, the student may lose mobility. If the front leg takes too much weight, the stance begins to lose its correct ITF structure.
Facing options
| Facing | Use in L-Stance |
|---|---|
| Full facing | Not a standard facing option for L-Stance in this reference |
| Half facing | Standard facing option, used to reduce the target area and support defensive structure |
| Reverse half facing | Standard facing option, used when the opposite side is turned forward according to the required technique |
| Side facing | Not a standard facing option for L-Stance in this reference |
Half facing in L-Stance
L-Stance is executed in Half Facing when the torso is angled so that the practitioner presents a narrower target. The shoulders and hips do not square fully toward the opponent. Instead, the body turns enough to protect the center line while still allowing the arms and legs to apply the required technique.
In half facing, the student must keep the stance measurements correct. The length remains 1.5 shoulder widths, the heel separation remains minimal, and the weight distribution remains 70% on the rear leg and 30% on the front leg. The facing changes the orientation of the body, not the identity of the stance.
Reverse half facing in L-Stance
L-Stance may also be performed in Reverse Half Facing. In this facing, the opposite side is turned forward according to the line and purpose of the technique. This creates a different relationship between the stance, the hips, the shoulders, and the direction of application.
Reverse half facing should not be confused with simply twisting the upper body out of position. The whole body must remain organized. The feet keep their correct angles, the rear leg keeps the majority of the weight, and the shoulders and hips rotate according to the required ITF movement.
Reference checklist
| Check | Correct standard |
|---|---|
| Stance name | L-Stance (Niunja Sogi) |
| Length | 1.5 shoulder widths |
| Width | Minimal width, with heels separated laterally by roughly 1 inch or 2.5 cm |
| Measuring point | From the inner foot-sword of the rear foot to the toes of the front foot |
| Weight | 70% rear leg and 30% front leg |
| Rear foot | 15 degrees inward |
| Front foot | 15 degrees inward from the line of attack |
| Facing options | Half facing or reverse half facing |
Common technical errors
The most common error in L-Stance is placing too much weight on the front leg. When this happens, the stance begins to look and feel like a different stance. The student loses the defensive character of Niunja Sogi and becomes slower when trying to move or counter with the front leg.
Another frequent error is making the stance too wide. L-Stance should have only minimal lateral width, with the heels separated by roughly 1 inch or 2.5 cm. A wider stance may feel stable, but it changes the structure and can make the body heavy.
Students should also check the foot angles. The rear foot turns 15 degrees inward, and the front foot points 15 degrees inward from the line of attack. If either foot opens too much, the hips and knees may lose alignment. If the feet are too straight, the stance may become uncomfortable and less stable.
Key principle
L-Stance protects the body by placing more weight on the rear leg while keeping the front leg light enough to move, block, or counter quickly.
Technical purpose
L-Stance, called Niunja Sogi in Korean terminology, is one of the most important defensive stances in ITF Taekwon-Do. It is used frequently in Tul because it gives the practitioner a narrow target, strong defensive structure, and a ready position for fast counterattacks.
This article is a technical reference. It focuses on the specific structure of the stance: length, width, measuring points, weight distribution, foot angles, and facing options. Students should use it to check their own posture, while instructors may use it as a simple correction guide in the Dojang.
