Active Isolated-Stretching - A Flexibility System

Active Isolated-Stretching - A Flexibility System: "Active Isolated-Stretching (AIS) is a flexibility system that involves working one muscle at a time. By actively contracting muscles opposite of the targeted muscle, Active Isolated-Stretching (AIS) automatically relaxes specific muscle in preparation of its stretch. Active Isolated-Stretching (AIS) is performed by gentle and quick stretches, and releases the muscle before it has a chance to protectively contract." To all my English and USA clientes and friends...a Merry Xmas, J. Simon.
