Ep 174: Matters of the Heart

Biomechanist Katy Bowman and biologist Jeannette Loram discuss Matters of the Heart. They cover the anatomy, tissues and function of the cardiovascular system, highlighting key concepts of heart health that are underappreciated. They discuss the importance of the flexibility of red blood cells, arterial walls and the heart muscle itself. They also explain the vital role of skeletal muscle contraction in healthy circulation. Muscle contraction during exercise not only assists the return of blood to the heart from the extremities, it is also the signal for blood vessels near working muscles to dilate or widen ‘pulling’ blood from arteries into the tissues. 

Katy and Jeannette talk about a movement diet to support the cardiovascular system. They emphasize the importance of higher intensity activity for taking the heart and arteries through their full ranges of motion. Their discussion also offers up a much larger buffet of exercise options than you might have previously considered. Strength training, big body work and stress-reducing movement all have complementary benefits for the cardiovascular system. 

Also in this episode Katy interviews podiatrist Dr Ray McClanahan, founder of Correct Toes and one of our podcast sponsors. Correct Toes are a toe orthotic designed to return toes to their natural alignment as the widest part of the foot. Ray explains the functional benefits of aligned toes, including improved balance, circulation and strength. Katy and Ray chat about how and why Correct Toes came about and they also discuss the future, with an introduction to some of Correct Toes latest products.

Bestselling author, speaker, and a leader in the Movement movement, biomechanist Katy Bowman is changing the way we move and think about our need for movement.

What is Move Your DNA with Katy Bowman?

Movement isn’t optional—our bodies need it to thrive. Many of us struggle to get regular exercise, and even when we do, it can fall short of truly nourishing the body from head to toe. How can we move more—a lot more—when parts of us are sore, stiff, or simply forgotten in our busy lives?

Join biomechanist Katy Bowman, M.S., and biologist Dr. Jeannette Loram on Move Your DNA, where big-picture science meets practical action. Together, they explore biomechanics, kinesiology, physiology, cellular biology, and natural human movement—and translate it into simple, effective ways to wake up your trillion body parts. With humor, curiosity, and a focus on longevity, Katy and Jeannette help you move smarter, move more, and create a more natural habitat for yourself and your communities in today’s mostly sedentary world.
