How to do it

1. Stand tall with your fingers resting lightly by your ears, elbows out wide.
2. Lift one knee up in front of you and crunch down and across, bringing your opposite elbow toward it - your torso rotating and folding slightly as knee and elbow close the gap.
3. Return to standing tall and repeat on the other side, alternating in a steady rhythm.
4. It's the crunch that counts: squeeze through your midsection at the touch instead of just tapping and moving on.
