Karlyn Pipes-Neilsen talks about "the power of the Y" and how swimming with an open and relaxed hand will help you engage the larger muscle groups (lats) for more power in your swimming stroke. This technique is used by many of the top swimmers in the world. With this technique, you'll have less tension in your hands, save energy, and have more power in your stroke. Using power paddles while training on the Vasa Ergometer will help you to learn and perfect this technique.
