Query: Fantastic!

This is my second review - it's more of a comment towards other reviews. Sure just like any video, you have to learn the moves or you will get hurt. I myself bought the four video package and I started out with the Basic and learned the moves before going on further. That's the only sensible thing to do. I have been doing this now for nine months without one injury sustained from this exercise program. I have hurt myself doing a structured step aerobics class at a gym - so a good trainer as Billy Blanks is, tells you to learn the Basics first, then proceed. When's the next video come out?
