A deeper look into three recent headlines in the body-nerd world. First up, recent research has shown that our skeletal muscles remember training at the protein level - no brain required! This is exciting research and Katy and Jeannette discuss the implications for exercise over the lifespan. Second, they dig into a recent study of uphill walking; the research suggests it is cheaper to take the steeper route, but energy efficiency might not be the only consideration. Finally in response to the online noise about recent changes to the CDC developmental guidelines, Katy and Jeannette explain what has really changed and whether it should have caused such an upset.

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.
