S.S.
I used to be an aerobics instructor and still work out everyday in an aerobic class that has alot of pilates influence, I had twin boys and got huge, my tummy is flat and I do beleive the elongating you get from pilates would be great for you, the Windsor pilates is good, also I take and taught jazzercise, if you don't want to goto the class they have a great exercise video for sale called "Dancing Abs" this will really concentrate on your core, but you need to concentrate on your core the entire time you are doing it in order to ensure the right results, another reason i say that is it is very easy to form your abs outward instead of inward with the wrong technique, especially crunches that focus on your lower abs when your legs are lifted in the air. always remember to concentrate on holding the abs in and exhaling on the exertion, get some Pilates video in conjuction with the Jazzercise, this will do I promise, just be consistant.
