Chi (vital life force):Qigong (pronounced chee-gong) is a thousand year-old Chinese practice designed to promote the flow of chi, the vital life force that flows throughout the body, regulating its functions. Stand with your feet shoulder-width apart and parallel. Bend your knees to a quarter-squat position (about 45 degrees) and keep your upper body straight. Observe your breathing for a couple of breaths. Inhale and bring your arms slowly up in front of you to shoulder height with your elbows slightly bent. Exhale while stretching your arms straight out. Inhale and bend your elbows slightly and drop your arms down slowly until your thumbs touch the sides of your legs. Exhale one more time, and stand up straight.
