Hwarangdo is a Korean martial art that combines elements of self-defense, physical fitness, and mental discipline. It was developed in the 20th century by Joo Bang Lee and emphasizes techniques such as striking, grappling, and joint locks. Practitioners also learn forms, or hyung, which are choreographed sequences of movements. The philosophy of Hwarangdo is rooted in the ancient Hwarang warrior culture of Korea, which focused on moral integrity, loyalty, and respect. Training often includes meditation and the study of traditional Korean values, aiming to cultivate both physical and mental strength in its students.
