Phantom Kung-fu is the fighting art of Tai-chi-Chuan (The “Grand Ultimate Martial Art”). This system evades the strikes of the opponent, delivering its own powerful internal energy strikes in such unexpected ways as to seem that one is being attacked by a phantom. This first volume details the kinds of punches, the body mechanics to make the punches powerful and the use of internal energy in the strikes. Master Bob Klein uses the wave bag to teach the techniques.
