We'd love to give you a pass, but every expert we polled said that exercise is nature's Midol. You break a sweat and you get a rush of happy-making endorphins--key at that time of the month when they're naturally at their lowest levels, says Pinar Kodaman, M.D., assistant professor of medicine at Yale University.

The Move: Legs Up the Wall
Lie faceup with legs extended up wall, feet flexed, arms at sides. Place rolled towel under hips. Hold 3 minutes.
Why It Works:
- Pressing into the towel helps release tension in the lower back.
- Your pelvis is tilted up, changing circulation and easing cramps.
