Barbara, I do have the Billy Blanks 2004, which has 4 parts: Foundation, Energy, Strength and Power. So far I've only gone through Foundation, and it is wonderful! It teaches you in a step-by-step fashion how to correctly perform the punches and kicks. I haven't gone through the other three DVD's yet as weight training keeps me busy, but after doing Foundation, I know I will love this series. I will, however, have to get used to his teaching style. I work out with Cathe everyday and switching instructors will be an adjustment.
I have his old DVD's that I got from E-bay. So far I've done his Abs workout and it is a good low-impact, high-intensity session. What I don't like about it (this is from his Get Ripped series) is the production quality. The workouts consist of chopped-up segments from his many live classes and sometimes you only get to work one side of your body, which leaves you feeling somewhat unbalanced. But the 2004 series has better production quality. I feel more like I'm part of the workout than just a spectator following the moves.
