New Nightmare=Jillian Michaels

Holy Crap.  Today I worked out the first time in a while.  I searched for home videos that I thought would work and that I could easily incorporate into my daughter's short 45 min. nap time frame.
I picked: Jillian Michaels "Ripped in 30" video.  (Disclaimer: I seriously doubt there will be any ripping in 30 days unless you count my overly tight workout pants).
I picked it because:
1. It is only 24 min.
2. It uses circuit training of 3 m. strength, 2 m. cardio, and 1 m. abs (repeated 3 times)
3. There are 4 completely different workouts on the DVD (I get bored easily)
4. I have some friends that vouched for it

After Day 1 or her Week 1 segment I can tell you that Jillian Michaels is serious about getting you ripped.  All of her exercises were truly hard, and I'm guessing that I will be repeating Week 1 before I move up to Week 2.  However, I LOVED the circuit aspect of it and the 24 m. flew by leaving me extremely sweaty.  I am hoping this will help keep me motivated!
Any other suggestion videos?
