Haven't tried it yet
I bought the entire set last year while I was doing ChaLEAN Extreme because I was looking for something more intense after it and it seemed to be what I was looking for. I haven't tried it yet though - it is a little intimidating especially when my workouts haven't been consistent for the last few months. I really like what I have seen from previewing the workouts and am planning on trying it out in a few months when I'm working out more consistently and feel in better shape. I think you will really like the workouts.
