Anyone do any ballet type dvd's?

Have seen a few dvds which look quite interesting

Element: Ballet Conditioning [DVD] [2007]: Amazon.co.uk: Elise Gulan, Andrea Ambandos: DVD

Ballet Workout For Legs, Bums & Tums - Joey Bull - Fit for Life Series DVD: Amazon.co.uk: Ken Gray: DVD

New York City Ballet - The Complete Workout Vol.1 And 2 DVD 2006: Amazon.co.uk: Richard Blanshard: DVD

To name just a few.
Wondered what you thought of this type of workout? I used to do ballet when i was a kid but obviously a few years have passed since then

Did nobody reply to you? I have just done the new York city ballet DVD for the first time after owning it for years. Will let you know how I feel tomorrow but I think it's good. It sort of creeps up on you. Kind of like yoga ish in the beginning and works up to gentle cardio. I am in early pregnancy so perfect for me, no bpm above 140 allowed.
