I did it
. And it wasn't so bad at all. I bought a ballet workout DVD, so it's mainly stretching and muscle building. There is a cardio part, too, but if I jump on my wooden floor at 8 in the morning, my flat mates will not be very happy
. I'll save that one for the weekends or something.
I'm glad your first day was successful too
Good luck tomorrow, for the both of us!
