The 10 minutes of the first version weren't enough to consider the workout "INSANE"?
With this new level we have increased the duration of your "suffering" by 30%, by extending the workout to almost 20 minutes. How have we managed to do it? We have been utterly "cruel": we have introduced new advanced level exercises, by increasing the series and, above all, decreasing recovery times. We have also associated an even "STRONGER" soundtrack. What are you waiting for? Challenge yourself!
