Book excerpt: - Learn about how your swimming machine works- Understand why you feel the way you do in practice- Over 300 illustrations to help you grasp the tough conceptsDon't be afraid! This is not biology class, this is swimming class. Your body is a Swimming Machine with a lot of moving parts. Knowing how these all work can help you understand why you feel the way you do at practice, why you train the way you do, and why you race the way you do.Complicated exercise science is translated into simple "picture book" format by Swim Smart founder Karl Hamouche, MD."Karl's book has helped me understand and even enjoy the very difficult topic of human physiology. I laughed (who knew Glycolysis could be funny?) and I continue to refer to various chapters throughout the season for support and clarification.Karl explains the complexity of the human body in clear, simple language that helps both coaches and athletes get straight to the point: "How can I go fast!?!" For example, last summer I read the Taper chapter to my group three weeks before our big meet and we had the most drama free Taper I've ever been a part of. We had a common language and noticed and named every stage along the way, and this helped all of us feel confident in the process and normalized the sensations that generally trigger uncertainty and doubt. We're doing the same thing with energy systems and I've never had more buy-in with both specific sets and overall cycles because we've got clarity around their purpose. Thank you, Karl, your book has helped me be a better coach!"- Megan Oesting, ASCA Coach of the year 2019, head coach of Eastern Iowa Federation and founder of MOSTswimtech.
