Sorry, I'm seeing this on the Insanity challenge, not the P90X challenge, but was curious. Have you done a round of P90X yet? I've done P90X and am in my first 2 weeks of Insanity. They are such different workouts and my goal when I'm done with Insanity is to do the hybrid. I think the hybrid will be a good mix of cardio and strength. Hope it works, you'll have to keep us posted.
Goal 3: 125 whenever I get there
Goal 2(restart): 130 by May 25th (2013 vacation)
Goal 1: 135 by May 24th (2012)~~~~Accomplished!
