Get Olympic abs

In just a couple of weeks we're going to be watching some of the world's most elite athletes compete. From beach volleyball players to swimmers and almost every sport in between, one thing you're sure to see on your TV screen are some rock-hard abs.

Core strength is so important to many sports. Women's Health Magazine got some tips from Olympic trainers on developing those gold medal abs. Some of the moves are:

• Hanging Straight-Leg Raise. This move is no joke. (My abs are aching just reading about it.) You'll hang from a pull-up bar then, keeping your head and back straight, slowly raise your legs until they're parallel to the floor.
• Walking Lunge Plate Twist. Hold a 10 to 25-pound weight plate in front of your chest and stand with your feet hip-width apart. Lunge forward with your right leg until it's parallel with the floor. Twist your upper body 90 degrees to the right. Return to the starting position and repeat on the left side.
• Twisting Windmill. Lay on your back with your arms out to the sides. Raise your legs until they're perpendicular to the floor. Slowly lower your leg to the left side of your body. Lift and repeat on the right side.
