Mischa Barton

But this wasn't just a regular trip to the gym - Mischa Barton went to Reebok and Cirque du Soleil's new fitness project called "Jukari: Fit To Fly." According to Reebok, the workout "gives the sensation of flying while strengthening and lengthening the body through cardio, strength, balance and core training."

Sounds pretty awesome to us! But do you think this is the ONLY thing Mischa's doing to maintain her slim figure?
