Join Malcolm Clemens Young for a conversation with Bonnie Tsui about her latest book, On Muscle: The Stuff That Moves Us and Why It Matters.

In On Muscle, Tsui brings her signature blend of science, culture, immersive reporting, and personal narrative to examine not just what muscles are but what they mean to us. Cardiac, smooth, skeletal—these three different types of muscle in our bodies make our hearts beat; push food through our intestines, blood through our vessels, babies out the uterus; attach to our bones and allow for motion. Tsui also traces how muscles have defined beauty—and how they have distorted it—through the ages, and how they play an essential role in our physical and mental health.
