A house that makes you lose weight. Wouldn't it be awesome if, just by stepping foot in your own home, you'd be on your way to a healthy weight? It's not so simple, I'm afraid.

But AOL Home has a slideshow of some pretty wacky house designs that surely must help their owners live a healthier lifestyle. How about a ten-story home that's only equipped with stairs? Or a house that's built like a jungle gym? Or a house on an island that can only be accessed by rowboat? The sheer act of getting to and/or around these houses is a workout.

If you look around your home, you'll likely see less extreme ways that it can help you get fit. How about making two trips every time you have to go up the stairs? Or playing a game of basketball with that hoop you have outside? You can also engineer additional fitness opportunities -- like putting up a rock wall in your garage just like one of the families in the slideshow did.
