Low Stance, Correct Stance

My teacher advocates us to use a low stance when pushing hands. I try to do as low a stance as I can, because it helps to train up the strength in my legs and because a firm base is important. But one must not forget that the low stance is a method to train a firm base, yet it is still important to be correct in your stance. You must be able to turn your kua, and you must be facing your opponent. If your stance is low but incorrect, you are just training your legs to be strong; it is like stance training, you are better off just standing in a horse stance and not moving. Your stance must be low and correct, in order for you to be able to translate your force from the legs up through the body to the arms.
