Stances are fundamental to the practice of KungFu. They are usually the first thing learned, but it usually takes a student a long time to realize how important they are. On the first day of learning every new student is usually taught the basic stances such as: Horse Stance, Forward Stance, and Cat Stance. And usually during his first lesson, the student can’t wait to get to the good stuff. They want to learn the fancy movements, the high kicks, or the devastating fighting techniques.
It isn’t until the student has trained for a long time that they fully appreciate the importance of stances in Kung Fu. The stances seems so basic, in fact it’s taught in the first lesson, but it is the fundamental aspect of training that determines whether the practitioner has developed real skill.
Usually when a novice sees a performance of Shaolin Kung Fu they look at the hand motions. When an experienced practitioner views a performance, they notice the stances and bodywork because these are the things that drive the hand motions giving them power and effectiveness.
