lola, you're gorgeous and there is nothing about your body that you should be ashamed of. Like others have suggested, it's probably more toning that you need, so I'd suggest a weights regimen at the gym about 3 to 4 times a week for around 45 mins would probably be about all you'd need. Over here we call them circuit classes where you do one or two circuits of all the weights equipment to get an all over workout. It's not so much cardio work, but I personally think that if you were to tone up you'd have nothing to worry about. You'd also be inclined to slouch less because your muscles would hold you up more easily.
