To stay in shape, Elle Macpherson shakes things up -- literally. The Aussie supermodel and host of Britain's Next Top Model uses the Power Plate, which gives her a total-body workout in just 30 minutes using scientifically-proven vibration technology that increases muscle reaction during exercise. "Even after only two weeks, I can already see a difference in my legs and stomach," says Macpherson. "Everything is so much firmer." Get to your local gym to try out the machine, which reportedly helps increase strength, muscle tone and flexibility. You'll be strutting your stuff down the sidewalk in no time!
