Here are a couple of photos that Hilary Duff just tweeted featuring her sexy little self doing some strange yoga stretches with her trainer that look so freaking hard that I’m getting a workout just looking at them. Damn! Well, these shots explain how the Duffster looked a hell of a lot slimmer (and way sexier) in yesterday’s post all of a sudden, eh? Hell, I wouldn’t even be able to do the easy part and hold the Duffster up with my legs… but I wouldn’t mind trying. Enjoy!
