EVF is indeed important but let's not forget

EVF is not a style it's simply a necessary position required for efficient swimming. With that being said, an Early Vertical Forearm position is a prerequisite but swimmers must work to keep that vertical position as long as possible. So, getting your hand/forearm vertical early is the first thing you must do then you must keep it vertical as longer. The Austrailians have spent a great deal of money/research on this important swimming skill. Every stroke, including breaststroke revolves around this premise. The lift forces (sculling) in breaststroke are important but swimmers and coaches should be trying to improve drag force (pulling backward) along with sculling motions. So, from straight arm pullers like Bernard) to bent arm to bent arm pullers like Addlington, EVF and the length of time in the vertical position is crucial to swimming speed. It doesn't matter if your a sprinter or distance swimmer, open water or in the pool, improve it and you'll be swimming faster. Good luck, Coach T.
