Query: A great sweat!

Oh my God, even after several years of doing the same advanced workout, #1 I prefer, it kicks my butt. Great for balance. I have become comfortable with it enough to modify certain moves, to intensify even more. He is somewhat showoffy, but I can ignore that in this workout. Not so in the newer Tae Bo Extreme - what a pathetic waste of time! He must throw water on himself off-camera, because I barely worked up a sweat. The only thing extreme about this workout is the ego trip he is on.
