This Keup So (급소) course introduces Tang Soo Do practitioners to the study of vital points, focusing on anatomical weaknesses that can be used for effective self-defense and a deeper understanding of the human body. Students learn how precise targeting, angle, and control can amplify technique without relying on size or strength, improving both defensive effectiveness and overall martial awareness. In addition to combative application, the course explores how this anatomical knowledge supports safety, recovery, and long-term health when training responsibly. By developing respect for the body’s vulnerabilities and capabilities, Tang Soo Do practitioners gain a more intelligent, efficient, and disciplined approach to self-protection and personal training.
