I had been wanting to do kickboxing and had purchased Billy Blanks Tae Bo instructional and Basic Tae Bo. I know it's the substance of the workout that matters, but I didn't care for the loud screaming roomfull of people counting in the background or how Billy stops demonstrating and starts walking among the people. At the advice of many of the other Cathe-ites on this forum here, I've just ordered KPC and Kick Max and I can't wait to get them! Just knowing from her other workout videos that Cathe is so great with cueing and careful with instructions, I know I'll enjoy them.
