David Kirsch, trainer to the stars, tells you how to get that celebrity bod for your wedding

Karolina Kurkova's Fully Toned Body

Exercise: 30–45 minutes of cardio every day

Works: trims and tones all major muscles

How to do it: Choose a form of cardio that helps you get your heart rate up—really up. I recommend running, rowing, swimming, cycling or elliptical trainer. Keep at it without stopping for 30 to 45 minutes.

Where to focus: Focus energy on pushing the envelope. You should feel out of breath and your heart rate should be up.
