What does Jang Kwan refer to in martial arts?

Jang Kwan refers specifically to the "heel of palm" in martial arts terminology. This technique involves striking with the heel of the palm, which is often used for various offensive strikes and defensive maneuvers. The importance of knowing how to use the Jang Kwan effectively lies in its ability to generate power while minimizing the risk of injury to the hand, as striking with the palm creates a larger surface area and promotes proper alignment of the wrist.

Understanding the concept of Jang Kwan is particularly vital in self-defense situations and sparring, as it allows practitioners to execute strikes that are both effective and safe. This technique complements other striking methods, providing a well-rounded skill set for martial artists.

The other options represent different aspects of martial arts but do not pertain to the specific technique of the heel of palm. For instance, a side stance describes a particular posture, spiritual power exercise would refer to practices that focus on mental and spiritual development, and free sparring relates to practice sessions where martial artists engage in controlled combat to apply techniques. Each of these has its importance in martial arts but does not capture the meaning of Jang Kwan.
