Oh too funny...I was in your shoes a few weeks ago. My 6 year GD was doing the dance 1 and I knew I had it at home but hadn't even opened it. I tried it the next day and was hilarious...boy was I BAD! Then the next morning I was worse than BAD -- I was not only BAD I was sore! So I can safely say, "I feel your pain".
Work it out girl, work it out.
