Chi Kung is a healing art that combines posture, movement, breathing, and concentration to develop and strengthen the flow
of the vital energy- Chi. Ultimately, strengthening the flow of Chi heals the body and the mind. It is both a preventative and self-healing technique.

To practice Chi Kung, a series of simple movements while standing in specific postures are repeated, and through concentrated visualization Chi is directed throughout the body. The meditative techniques and vibrant movements increase strength, stamina, flexibility and concentration.
