The HIIT workout blasts a lot of calories. I did the one on the original DVD this morning, which includes 4 sets of the high intensity work - this included burpees, squat jumps, and a couple of other moves I don't know the names of. So you do 4 moves and do each move for 15 seconds, then repeat the whole thing 4 times through. Then between each burst of intensity you do toning exercises. I love it!
I couldn't recommend the DVD's more. I have both DVDs which they have come out with and I will definitely be buying the next one if they come out with another and I really hope they do!
