Query: Disappointing

I love ballet, so I thought this would be a fun workout. I was wrong. If you don't already have high flexibility, you will be more frustrated then energised. The instructions are vauge. There are few moderations given, and you can easily strain a muscle. Beware if you are exercising in a room with fragile items, as there is a section of constant jumping. I left this workout annoyed at my wasted time and will not return again.
