I love this workout! I don't do specific rotations, and don't look for "results", but I can tell you it's fun and tough!
There are three 25 minute workouts, getting progressively more challenging as you go. Although, in my opinion, Level three is easier than level two.
I like the fact that you can do just one level if you're looking for a quick intense workout.... or do two in a row if you have more time, or do all three if you've got the time and the energy.
