Chi Kung (qigong) is the ancient Chinese art and science of using posture, exercise, breathing, and concentration to gather and promote the strong flow of Chi, or energy, ultimately healing the body and the mind. Chi Kung is the foundation of traditional Chinese medicine and is both a preventative and a self-healing technique. It is practiced by more than 80 million people in China and is gaining in popularity in the west. Students learn to open and control the flow of Chi so that it spreads evenly through the body, eliminating any blockages and, thus, filling any areas of the body that are depleted and draining any areas that are congested. The combination of meditative techniques and dynamic exercises improve posture, circulation, strength, stamina, flexibility, and concentration. These exercises are the most basic and can be practiced both standing and sitting and are suitable for anyone.
