Bad news: a poorly-designed exercise program that might really be injurious to those few able to do it. Norris, a karate-champion-turned-martial arts-film-star (""if you want to be entertained, you'll like my movies""), purportedly based the program on the principles and techniques of the martial arts, but one look at the ""warm-ups"" shows that something has been left out. ""Bouncing"" (a sort of running in place), jumping rope, ""cannonballs"" (similar to the familiar ""squat-thrusts""), and Chinese push-ups (extraordinarily difficult) are not generally considered to be warm-up exercises. The next stretching section includes the discredited hurdler's stretch (famous for causing knee injuries); while the ""Strengthening and Toning,"" ""Belt Isometrics,"" and ""Weights and Buddy Exercises"" are disconnected and generally not within reach of the average exerciser. But the chances for injury make this a loss at any level.
