IT'S ALL ABOUT THE HIPS
Using the hips is probably the most important part of making your martial arts techniques effective. Many people will punch and kick and only think of the hands or feet. This is essentially the same thing as focusing on the arrow while having a poor bow at the same time. No matter how nice and sharp your arrows may be, without a good bow to launch it, it will be useless. That's why we always emphasize the hips and feet for proper movement as well as power and health benefits.
