Here's how to do it: Lie on your back with hands behind head, knees bent to 90 degrees. Inhale as you lift your shoulders to crunch up; hold for 3-5 seconds. Extend your legs to 45 degrees and hold for 3-5 seconds. That's one rep. Do 10-15 reps, and aim for 2 sets.

Trainer tip: Focus on contracting your abs and keeping your back flat against the ground.
