Good question about how I did Insanity. Umm, it was a mix of stubborn and determination! I started Insanity at 430+ not 500. But, what I did do was what I could. I couldn't do everything on the video (and honestly at 294, I still can't). None of those people in the video are over 15% body fat so how should we expect to keep up 100%? WE CANT! So don't try to. Do what you can. Modify. Take breaks. It will get easier but it never is easy! Give it a try but expect it to be hard because it is! But it works!
