I bought this one on pre-sale. I've done the whole workout twice and it seems to be a reasonable calorie burner per my HRM. I can't say that I absolutely loved the core cardio part, but to me the Cardio Burn section is worth the price. The cardio burn is not long enough on it's own to be one workout, but it's a great add-on. It has Christi's usual fun choreography with a cool upbeat song. But I have to warn you though, it's one of those tunes that stays in your head for the rest of the day!
The workout calls for a soft touch med ball. I found that my soft touch med ball is a little too large in diameter to use as I can't palm it like it's called for in the video. However, I've used a 5 pound dumbbell instead without a problem.
