Rooting power and correct structural alignment provide the basis for Tai Chi and Chi Kung practice. Iron Shirt I starts with rooting practice and grounding. Through essential standing postures, breath exercises and work on opening of the primary Yin centers (Perineum and Kidney 1 Points), a deep sense of rooting and connectedness with the earth is developed. Simple standing in prescribed postures develops correct structural alignment, greatly aiding Chi flow. Connection with the inexhaustible energy source within the Earth and the absorption of this energy into the fascial tissue builds physical and energetic resources and protection. With the supporting fascial tissue charged with energy, the resistance of the organs to injury and disease is greatly enhanced.
