Leading USA Swimming Coach, Matt Kredich (University of Tennessee) uses his "old friend", the Vasa Swim Trainer to teach proper butterfly pull stroke mechanics. Olympic medalist, Christine Magnuson demonstrates.
A proper Butterfly pull is important for positioning as well as propulsion. Focusing too much on propulsion can put a swimmer in the wrong position too soon. Coach Kredich explains why using a Vasa Swim Trainer makes it easier to diagnose and correct stroke technique errors in butterfly and other strokes.
This video clip is part of Coach Kredich's outstanding DVD, "All Access Butterfly", by Championship Productions.
