16 of 20 gold medals and 43 of 60 medals at the last games were won with an Early Vertical Forearm (EVF) position or “high elbow stroke”. The former president of the American Swimming Coaches Association said that the EVF is the component that separates every level of swimmer. At the US Nationals, 11 national coaches were asked what part of the stroke was the most important and 9 of the 11 said EVF. Early Vertical Forearm (EVF) Swim Training is a sure-fire way to get faster.
