I'm 5'9" and I weigh 135 pounds on my good days, so I don't want to lose any more weight, but I pretty much have no waist at all. I would describe my body type as an inverted triangle or rectangle.

I've tried a million ab exercises and they do nothing. All I want is a lovely, cinched in waist!! Losing weight didn't do it, and ab exercises just made it more muscular and masculine looking. This is so aggravating. Are there any exercises that truly cinch in your waist and don't just promise to?
