this was my first intro to bellydancing. jenna is a great dancer, with a no nonsense respectful approach to this art form. i get the impression that she loves her job. there are easier dvd's out there for a beginner, but this is doable. it just takes practice. it took me roughly 3 months from warm up through to the presentation. but i got it down now and it really does a number on your core. good authentic music too.
