Hi and welcome, MSJAY!
I want to be glib and say you'll love this dance form! I can say with confidence that you'll come to love the people here, though. All so supportive and helpful!
I'm with Angelia - not all dvds or instructors are created equal! Which one do you have, and then maybe we can recommend others that might be easier to follow. It's always better with new forms of excercise to find a real live teacher in your area if you can --- www.shira.net is a great resource for that, reviews of dvds, and all manner of other things bellydance.
Again, welcome, and be sure we'll talk your ears (type your monitor?) off if you let us!
