txlawchic-
I have PLENTY of insight for you!
The first thing I want to adress is the tummy issue that you mentioned. Just like with any exercise-to lose weight you have to eat right as well as exercise. There are many wonderful belly dancers that are of all shapes and sizes-from way too thin-to very heavy. A lot of this depends on their diet. You can do 30 minutes on the treadmill every single day-but if you eat more than you burn-you will still be overweight. This is with any exercise.
Second-up until the past couple of years-before the "low rise" pants fad-most women's pants/skirts were made to hit at the natural waistline-at around the naval area. This for most women (with exception of apple shapes) is the narrowest part of the waist. Even the most fit abdominals are the flattest from the ribcage area to the naval-and almost all-even tiny tummies-have a slight "pooch" below the naval area. This is the area that holds the uterus...so it will pooch slightly anyhow-and is the hardest part to "get back in" after having a child/children.
Belly dance costumes are not worn at the natural waist. They are traditionally worn lower-close to the hipbone area-so the "pooch" from the uterus is visible. It may seem strange at first-but you will soon get used to the look.
Almost everyone who I have seen wearing "belly shirts" and low rise jeans-even 15 year olds-have the little place there where the uterus is.
The toning and sculpting benefits of belly dance are numerous-and it really depends on what you are doing. Doing veilwork, snake arms and shoulder shimmies are great arm and shoulder exercise...there are a zillion things such as Egyptians, hip shimmies, and hip lifts and drops-just tons of things that provide cardio benefits and tone the legs and hips. Ribcage slides, hip figure 8's and such do great oblique/waistline work.
The abdominal work depends on what you are doing. Most movements in belly dance move "through" the belly...rather than focusing on the belly alone. When you do ribcage work-you belly moves in reaction to that...when you do hip circles-your belly moves in reaction to that...there IS some ab only work-but most of it is learned in more advanced belly dance training-such as belly rolls, Turkish Folds (belly dance backbends) and so on.
I do it as one of my exercise forms-but I am truly in love with it. I have completely dove into learning all I can...whether it be about Middle Eastern music and its various regions and rhythms-to the different forms of belly dancing-I am trained in cabaret, American Tribal Style, and now learning Turkish Rom as well. Mauvais started with cabaret and is now learning Turkish as well.
Swords...finger cymbals...candles...veil...double veil...there are just SOOO many things you can learn if you find that you love it enough to do so.
Most professional belly dancers are not doing it for "exercise". It is wonderful exercise-but it is also an ancient art form-with many, many things to study and learn.
One thing I think that it is important to stress-is the attitude that you will find with women in the belly ance community. It embraces the beauty in every woman-women of all shapes and sizes look wonderful belly dancing and are welcomed! It is something that I actually find refreshing-because the women have "real" bodies. Some have spectacular figures...while others have a flaw here and there (like most of us) and it is refreshing to see. You can concentrate on your workout, or what you are learning that day-and forget about your stretch marks or tummy pooch for a little while. Belly dance is an excellent exercise...but those who end up being serious about belly dancing do it because we love it-and sort of forget that it is exercise.
For me personally-I have found that belly dancing shapes your body-but in a more feminine way.
I have lost inches and become shaped differently in the past two years...I have slimmed in some very feminine areas-my ankles have gotten thinner for one...yes, it sounds strange-but they have. They look much prettier in sandals than the tree trunks I used to have.
I have had two children-and still have a touch of "pooch" in my lower abs...but I have lost 7 inches off my waist in the past 2 1/2 years. (I have lost a lot of weight in that time-but my inches lost everywhere else has been 1-5 inches...my waist being slimmed the most by far!) Even though I have a touch of pooch-I have gained massive abdominal strength-and have the definition lines running down my ab area-from my ribcage to below my naval area. My shoulders and neck have slimmed and gotten a lot more shapely...and I have (for the first time ever in my life) achieved a muscle definition line on the sides of my thighs. *Belly dancing is done with the knees bent slightly-so the whole time you are dancing it is like you are doing a slight squat like in strength training.* But-I have a feminine shape-because my butt has lifted and toned, but my buns and thighs have stayed full/rounded...as have my breasts.
Basically-you achieve a more feminine "hourglass" shape over time if you do it enough...you thin out in areas but don't become a "stick". It is a nice sillhouette.
