“Rolf Structural Integration involves lengthening. That's the only way to straighten a body. If you get a longer body you also get a thinner body; you can't do one without the other. Watch as people get up and walk after a Rolfing hour, you'll see that a body is longer. There are so many little places, joints, and ligaments where you get a little increment of length." from Rolfing and Physical Reality by Dr. Ida P. Rolf Ph. D.
