Katy Bowman and Jeannette Loram explore skin strength, focusing on what a callus is, how calluses form on the hands and feet, and how it affects circulation. They also discuss the pros and cons of calluses, comparing them to a weight belt for your skin—reinforcing, protecting, and ultimately enabling your body to do more.

They share personal stories—from rowing and kayaking to gardening—highlighting how it's often skin, not muscles, that limits activity. Katy also chats with Karri Bowen-Poole, founder of Smart Playrooms, about designing home spaces that promote hanging, build skin strength, and support kids’ physical and cognitive development. They cover equipment ideas, dynamic home design tips, and draw inspiration from Ninja Warrior athletes.
