Within the martial arts among the most misunderstood and grossly perverted concepts are stances.
Iain Abernethy once said, “We don’t get into a stance to do techniques; we do techniques by moving into stances.”
The function I see stances having is the development of effective movement.This is to say that the key component to learning the stance is not in the static fixed position but in the transition from one position to another. This means the focus has to be on learning the shifting of the center of gravity. Understanding how to shift center of gravity requires that you get the correct feeling for doing so. When the lower grade student shifts through stances what they are doing is learning to effectively move their center of gravity.
Kiba Dachi is also known as the horse stance
It will take a lot of consistent practice to attain the correct feel for the center of gravity and eventually shifting it will gradually become more natural and intuitive. Gichin Funakoshi’s seventeenth precept of karate covers this by saying, “Stances are for beginners; advanced students will use natural body positions”. Don't read too deep into this. It does not mean that as novice karateka we practice stances with intensity and then as advanced students discard them in preference of something else. It insinuates the “stances” of the novice become the “natural body positions” of the more advanced student.
Again in the words of Genwa Nakasone, “Karate has many stances; it also has none.”
