Here's how to do it: Lie on your back with knees bent. Straighten your arms by your sides, with fingers stretched out, and float your legs up to tabletop position. Inhale and scoop out your lower abs; then as you exhale, drop your knees slowly to one side. Come back to center as you inhale. Exhale and lower your knees to the other side. That's 1 rep. Do 5-8 reps.

Trainer tip: Keep the backs of your shoulders pressed against the ground, and focus on your core muscles.
