While I had my clinic in Scottsdale, AZ I treated many ultra-marathon runners and trail runners. These runners like others saw a huge improvement with their injuries and their performance. Walking and running are natural activities for our bodies. When performed with the help of gravity you move as if you are going downhill.
The elite runners in the study we did with ASU collaborated what my clients were experiencing. Rolfing fixes the problems, then enhances you ability to run naturally with more ease.
