Dr Charles Kenny, an orthopaedic surgeon who worked with the Baltimore Orioles baseball team, recognised that the early signs of arthritis were associated with stretching of the supporting structures of the knee. Accordingly, he developed exercises as an alternative to stretching which rest squarely on the latest scientific research about how the body works. This breakthrough title explodes the myths of stretching and gives everyone a scientific basis for the new paradigm to flexibility, health and performance.
