Billy Blanks is the popularizer of the super-active, high-energy phenomenon of cardio kickboxing. This video is a 30-minute introduction to the "full contact" aspect of kickboxing, using the kickboxing bag. The kickboxing bag is a long punching bag that sits on a base (rather than hanging from the ceiling). Not for beginners, the upbeat music and terribly fit assistants propel viewers through their workout, as does the inspiring instruction of Blanks. The action stops frequently for Blanks to explain and demonstrate the moves. ~ Leslie Birdwell, Rovi
