An effectively delivered kick can mean life instead of death in a self-defense situation, and glory rather than shame in the ring. When a larger or more powerful opponent is intent on inflicting harm, the superior strength of your legs can be used to tip the balance in your favor. However, gaining proficiency takes training and insight. ''Essential Book of Martial Arts Kicks'' has one purpose: to help readers hone their kicking proficiency so that they can readily deploy the most powerful tool in the fighter's repertoire.
