I've been using P90X but wanted a different cardio workout. This workout is very fun, and let me tell you, you work up a sweat. For me the hardest part was getting the choreography down, but after doing each workout a couple of times, I knew what to do, and really started enjoying it. The music is fun, Chalene's personality comes off the screen, and I love the fact that when we are working our left side she is working her right side so we are mirroring what she does which I think makes learning the moves so much easier.Once you learn the routines you have the option of turning up the music and not hearing her, but I'm not quite there yet.Anyway, I recommend it. You will need some hand weights for the sculpting workout, depending on your fitness level, anywhere from 1# to 10#.Because I liked Chalene and this workout I actually just ordered her new collection of dvd's called Turbofire, can't wait to receive it.
