I'm a curvy petite girl, and I love my shape! Wanted the shed ~12 lbs to tone up a bit and I've lost ~9 lbs so far... BUT whenever I start to shed my BUTT goes away! What's up with that!? I'm just running 3-5 miles a few times a week!? Someone please explain or let me know if there are any good workouts to keep my back side perky! lol
