Query: Great Workout

I am a FIRM veteran but this is the first time I've ever used this particular workout. If you're new to the Firm please realize that this tape, though a great workout, will take some getting used to. The changes between sets are QUICK and the moves - especially Kai's - are FAST. Don't get frustrated, it will take doing the tape 5, 10 times before you will be able to stay with them the entire time. That's the down side of all of the Firm's tapes. The up side is that once you know the tape, you won't get bored being taught the same move for the umteenth time (or hear that darned joke again), you'll just get on with your workout.By the way, even though I'm in good shape, I still found some of these exercises too challenging. I recommend that beginners use a shorter step (6" rather than 10-14") for Kai's kick-your-butt segments and use half the weight that Susan recomends in her segments.
