Workout Update: Insanity Max 30/Chalean Extreme/Body Beast/P90X Hybrid Day 15

Day 15 was the Cardio Challenge workout again. I made it past the twenty-minute mark today, maxing out at just over 21 minutes. The last two rounds of moves definitely wear me out though, so I am not sure if I will make it past 25 minutes in the first round of this. But, I can tell my cardio endurance is getting better, so I am making progress.
