I'm talking from the grave because I did insanity. It is insane, or at least the people who do it are! Felt great until the next week I could barely walk xD But I keep up at it, kinda. I do it every other day instead of every day, until I get better then I will go to everyday like it should be. By July I should be doing it every day. It's all about steps, you don't want to just start off sprinting. Also the hardest part for me is eating healthier, I cook like early Paula Deen xD 4 sticks of butter an everything~
