jillian michaels 3 day shred

So, either I'm way out of shape, the extra 20 pounds I've gained is affecting me, or both, but I just did day 1 - level 1 of Jillian Michaels 30 day shred and OMG I'm gonna die. I couldn't even do the advanced versions! OMG. Not to mention I am DRENCHED!  I'm gonna go lay on the floor and die now...🙁
