When doing Choi Kwang Do Patterns, you must be like a "Jedi Knight" and be mindful of each and every technique, body position and target area. Using your whole body properly not only increases your effectiveness, but also your aerobic conditioning by moving the big muscles groups through each movement and having efficient motion in general to make it smooth and flowing. So, watching your stance, weight shift, using all joints and in order, with proper guard, makes the difference between doing Choi Kwang Do properly and effectively.
