While learning the movements of basic postures in martial arts is naturally necessary, understanding these basic postures according to the principles of body movement is essential to improve one's own techniques to the next level.

This understanding must be achieved through a musculoskeletal approach, learning their functions and efficiency. Otherwise, it is almost impossible to advance beyond the first or second levels out of nine levels in one's martial arts skills.

I found some incorrect parts in the explanations of the Jayeonsae (natural stance), which were posted on Facebook last week.

Consequently, I would like to comment on the explanations of the Jayeonsae as follows, with the hope of assisting HK practitioners in enhancing their skills.

《 Explanation of Jayeonse (Natural Stance) in Haedong Kumdo 》

1. Understanding Jayeonse from a Musculoskeletal Perspective

The correct posture of Jayeonse should be based on the natural flow of movement, which helps improve mobility and physical functions such as balance, endurance, agility, and flexibility.

The movement of posture must always be linked to breathing, which is a crucial factor in all martial arts.

2. Principles of Basic Stances in Haedong Kumdo

Jayeonse (Natural Stance), Daedose, and Soodose, etc. must all align on a straight line.

In striking martial arts, the basic stance typically places the feet shoulder-width apart, whereas in Haedong Kumdo's real sword training, maintaining a straight line alignment is essential.

To fully understand this difference, one must consider the musculoskeletal approach, its function, and its effects.

This section will focus solely on Jayeonse.

■ Explanation of Jayeonse (Natural Sword Stance)

1) Foot Position

Both feet should be placed on a straight line.

The right big toe should be naturally positioned on this straight line.

The distance between the front and back feet should be about half a step.

The left big toe should naturally point toward the left side of the right heel.

However, slight variations may occur depending on individual body structure.
 


2) Reason for Aligning Both Feet on a Straight Line

To maintain spinal alignment, ensuring a smooth energy flow.

To maximize the efficient use of the sword’s weight for proper sword handling.

To effectively channel energy from the toes to the sword tip.

If the feet are positioned wider than shoulder-width apart and a straight cut is attempted, the misalignment of the spine will result in noticeable physical strain.


3) Sword Position - Geonum (Aiming)

The sword position should be considered based on two key factors:

- My eye level

This is directly related to breathing training and meditative sword practice, which is integrated into stances like Jayeonse, Daedose, and Soodose.


- The opponent’s neck level

Ensures optimal efficiency in both offense and defense.

4) Arm Position

If both arms are fully extended while aiming the sword, it causes stress on the shoulders, leading to stagnation of energy flow.

In Jeongmyeon Baeki (Straight Cut), overextending the arms increases the risk of joint injury, reducing training efficiency.

In striking martial arts, fully extending a punch increases the risk of injury and creates vulnerabilities in the next movement—this principle also applies to sword training.

Maintaining a natural posture prevents arm injuries and ensures maximum training effectiveness.

If energy flow is blocked, achieving the ultimate goals of martial arts—technique, philosophy, and healing—becomes impossible.
