Welcome back to the Threshold Lab. Today's guest brings a rare blend of experience to the show. He's an elite athlete, coach, author, and even a longtime podcast host as well. Today, I'm honored to welcome Billy Allen, who currently serves as an assistant coach and player development coordinator for the Stanford Beach Volleyball Program, and he's entering his third season on the farm in 2026. His first year at Stanford was a historic one. The program finished with its best ever record at 32 and 6, including 21 wins over top-ranked teams from across the country. Now, outside of coaching, Billy still competes on the AVP tour as a professional beach volleyball player. He's a three-time AVP champion and spent six years on the USA Beach Volleyball National Team, representing the United States in competitions all around the world. Now, on top of all of this, he's an author, a co-host of the long-running Coach Your Brains Out podcast, where he's interviewed some of the top coaching minds and thought leaders, not only in volleyball, but across different sports and within the world of high performance. So in our conversation today, we dig into Billy's perspective on the mental game from both sides of the net, what he's lived as an athlete, but also now what he sees and how it has shaped his perspective as a coach. We explore what he's learned from interviewing world-class coaches and thinkers, and how those conversations has refined his own coaching philosophy and approach, and we peel back the layers on his approach to skill acquisition, including the ecological dynamics perspective, and the way he designs training to help athletes become more adaptable
