Query: New York City Ballet Workout-- Nice to watch, HARD to do.

I bought this video because I enjoying many forms of dancing and thought that this would be a video I would look forward to popping in everyday. I have some background knowledge in ballet. I found this video very difficult to keep up with because their is absolutely no instruction as to how to do the steps that they are doing. I would probably have to watch the tape over and over in order to pick up these moves. It's a great informational video on the New York City Ballet dancers but I wouldn't waste your money if you're looking for a good workout (unless you're very experienced in ballet...and I mean VERY EXPERIENCED.)
