In DK Yoo's Warfare Combat System, breaking a brick involves a combination of proper technique, body alignment, and mental focus. To break a brick, the practitioner must first ensure their striking surface—typically the palm or knuckles—is solid and properly aligned with the target. A key principle is to generate power from the whole body, not just the arm, using a fluid motion from the legs and core. Proper body mechanics and relaxation are crucial, as tension can reduce the effectiveness of the strike. Mental focus and intent are also emphasized, as the practitioner must visualize the force breaking through the brick, channeling energy into the strike. This approach allows for a controlled yet powerful impact, leveraging the body's natural force to break the material.
