By opening the hips and lower back, this deceptively easy move yields great rewards. It's also possible to do discreetly in bed without waking the person or pet sleeping next to you.
How: Lie flat on your back. Hug your right knee gently into your chest. With each exhale, draw your knee closer toward your right shoulder. Stay here for five deep breaths, or until you feel ready to hug your pillow (or your partner) instead of your knee.
