I think though you can be thin and muscular at the same time...Before I became an avid cyclist ten years ago, I had been a runner for many years so I have gigantic quads but they are very trim LOL...not something that facilitates wearing the low rise type of jeans LOL...I have some ultra low rise but they are the ones from Old Navy with stretch...stretch is a good thing LOL...

I get to go to an Old Navy outlet tomorrow...yay! I didn't know there was an outlet not far from me...
