Query: Excellent abs, butt & arms workout!

I now own all 3 of the new Tracy Anderson Method dvds & this one is the hardest! I've been doing the mat workout 6x a week for 3 weeks & getting stronger & just did this post pregnancy workout & was whimpering like a baby during it because it was so hard! I've never had a baby but who doesn't need better abs? I love the ballet (classical) music & ballet influences to her workouts, she subliminally reminds us of the goal: to get a ballet dancer's body! (Strong & lean) That's what I'm committed to do this for! I love her instructional style: not much talking, just enough instruction. All 3 dvds arrived super fast too! Thanks Tracy, if you make them I will buy them! More please!
