Afraid To Workout???

They put so many disclaimers on the Insanity box that I am not even sure if I wanna go ahead with it right away!!! It says to consult a doctor before, I know they all say that but it says it many may times.
I am not in the best shape, but I am not in the worst shape either. I know this workout is supposed to be intense and you are supposed to be in fairly good shape before you start, but is it really dangerous to do it?

I doubt it but the disclaimers are freaking me out a bit. The only thing I can do is try it and see!! If I cannot do it or feel discomfort doing then I guess I will stop.

Here goes nothing...
knocks on wood...
crosses fingers...
gets out lucky rabbits foot...
