This Huberman Lab Essentials podcast focuses on building endurance for both mental and physical health. Huberman explains the science behind energy production (ATP), the role of oxygen, and the limiting factors in performance (nerves, muscles, blood, heart, and lungs). He details four types of endurance training: muscular endurance, long-duration endurance, and high-intensity interval training (HIIT) with both anaerobic and aerobic variations.
