Are you confused by all the social media messaging about muscle mass and strength training? Join us for this beefy episode all about muscle!
Biomechanist Katy Bowman and biologist Jeannette Loram discuss the clinical term sarcopenia– age-related muscle decline–and distinguish it from muscle atrophy due to disuse and sedentary lifestyles. Katy and Jeannette tease apart the different elements of muscle decline; mass, strength and function. They debate how each of these can be measured and their importance. Their discussion centers on a listener's question seeking to understand what we should be doing physically to prevent muscle loss.
Also in this episode, Katy has a conversation with Tyler Benner of
Venn Design, a company creating dynamic seating for homes and offices. Tyler explains how his background in physics and sport have contributed to his creativity in product design. Tyler highlights his solar and sports series of Air Chairs and explains how he has created designs that look exactly like a planet or a basketball! He also introduces his latest venture;
Strong Feet Athletics, creator of the first barefoot cycling shoe.

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.
