Long before the advent of firearms, Iron Shirt Chi Kung, a form of Kung Fu, built powerful bodies able to withstand hand-to-hand combat. Even then, however, martial use was only one aspect of Iron Shirt Chi Kung, and today its other benefits--strengthening the internal organs, establishing roots to the earth’s energy, and unifying physical, mental, and spiritual health--remain vitally significant for anyone seeking better health, a sound mind, and spiritual growth.
