The constant pull of gravity is the most powerful force your body will see during your lifetime. Inversion offers a system of stretching and light exercise that helps to slow or reverse the harmful, compression of the body by gravity. Used sensibly, inversion is extremely beneficial, and no more dangerous than many other popular and widely practiced fitness activities. The experience of thousands of people who invert regularly is that it gives them the relief from back pain they've been looking for. Just as important, they gain the rejuvenating effects of inversion on the entire body, providing health benefits far beyond the relief of back pain.
