Dr. Andy Galpin: How to Build Physical Endurance & Lose Fat | Huberman Lab Guest Series

About this video

Dr. Andy Galpin joins Huberman for the third episode in their fitness series, covering endurance and fat loss. Dr. Galpin reframes endurance as more than doing one activity for a long time, explaining the different kinds of endurance and the fuel systems that support repeated activity, alongside protocols to develop each. He also revisits why people exercise: to feel better, to look a certain way and to sustain that over time. The middle excerpt works through anaerobic fuel breakdown in detail, explaining ATP hydrolysis, hydrogen ions and acidity, and how pyruvate accepting hydrogen forms lactate. Dr. Galpin argues lactate is not itself causing fatigue; rather, he explains, it spares the muscle from free-floating acid and can be reused as fuel once oxygen is available or shipped elsewhere in the body.

Key takeaways
