(II) Stability: To ensure that the torso is upright and comfortable, it is first of all necessary to keep the lower limbs stable. The stances and footwork are the foundation of good Positions and movements. If the steps are too small and too narrow or the positions and angles of the feet are not correct, and the distinction between emptiness and solidness is not clear while executing the movements, instability of the body will result. Therefore, beginners must first have a clear understanding of the stances and footwork. You can properly grasp the timing for the change of body weight by practicing the stances and different steps separately. Or you can Practice the different leg techniques (heel, toe, and side kick) and do more exercises to improve the pliability of the waist. This can also increase lower-limb strength and improve the stability of the movements.
