Pure Insanity!

So..This week I've officially re-started (I started it 2 times before and only made it to workout 3) Shaun T's Insanity workout.





I've done P90X and I gotta say, I love Tony Horton to death, but Insanity is exactly what the name says it is. I'm wondering how long it took the people in the video to be able to do those HIIT- High Intensity Interval Training for those who don't speak "Workout"- back to back like they do. I'm dying over here, however I am SO determined to get into shape by March because if The Arnold is coming back to Ohio next year I wanna be there.. looking good!
