INSANITY!!!

Whose IDEA was it to purchase this horrible workout??!!...  The very first day they have you doing a tough plyometric cardio circut workout...  I almost died after the warm up!!!  "Shaun T.", the creator of this crazy workout, gives you a series of plyometric moves, (lots of jumping), and you start out doing them fast....and then he gets faster, and just when you think (or hope) it will end,... he goes faster... remember when I said I just watched my Mom go through a total knee replacement and how I was going to protect my knees from harm?...yeah, we will see about that...Shaun T.
