Stances and Basic Body Movements
Hanmi translates directly as half body stance. The front foot faces directly forward while the back foot is in-line and relatively perpendicular. Both feet are evenly weighted and are an appropriate distance apart allowing for easy movement in any direction. The knees are slightly bent with the back straight and shoulders relaxed. Arms are extended with hands open.
