VO2 Max Is Your Cognitive Reserve — Why Executives Operate in Constant Brain Fog

There's a moment when the explanation shifts from VO2 metrics to confession: discipline alone didn't carry him through. He broke. Stress accumulated until his physiology couldn't buffer the load anymore. This isn't about training protocols or fitness zones. It's about what happens when a leader running a manufacturing operation discovers that willpower fails when the body fails. In Health Is a Skill, Todd Vande Hei reframes aerobic capacity entirely—not as a fitness number, but as the clearest window into physiological robustness. Your brain consumes enormous energy. Leadership is sustained decision-making under stress. When oxygen delivery fails, so does clarity, emotional regulation, and cognitive performance under pressure. This episode maps the direct line between VO2 max and longevity, between aerobic capacity and the quality of decisions made when stakes are real. Vande Hei built Stark while operating at a scale where margin for error was thin. His health had to perform but didn't. He speaks here to anyone carrying real responsibility—anyone who has felt the weight of people, capital, and consequences sitting on their shoulders every day—about what it means to build a physiology that can actually handle that pressure, and why treating your body like a system, not a problem to willpower through, changes everything. About the Guest: Todd Vande Hei is the founder and CEO of Stark, a company built on the principle that health operates like any other managed system. He has spent his career applying manufacturing and operational excellence to human physiology, combining functional medicine with the discipline of corporate systems architecture.
