概要

 Dr. Mike Hart interviews elite runner Brady Holmer about endurance training, VO2 max physiology, and common misconceptions. Holmer explains that zone 2 builds the aerobic base and enables high training volume with less fatigue, notes heart-rate zones are ideally defined by lactate thresholds, and says he primarily uses perceived exertion rather than lactate or heart rate during training. He advises against guiding workouts by wearable HRV scores, arguing accurate HRV requires standardized morning measurements and that wearable data can create a nocebo effect; trends may be informative, but subjective feel should come first. They discuss polarized vs pyramidal training and typical 80/20 intensity distributions, effective session durations, mechanisms limiting VO2 max (central vs peripheral), and why Norwegian 4x4 intervals work by maximizing time near 85–90% max heart rate. They cover breathing/nose breathing, inspiratory muscle training, sauna/hot baths as performance adjuncts, nutrition timing of carbohydrates, and supplements including beetroot, beta-alanine, urolithin A, and post-exercise ketones. Brady Holmer is an endurance-focused performance expert and elite runner whose work explores the science and practice of aerobic fitness, VO2 max, recovery, and smarter cardio training. In this episode, he explains how zone 2 training builds the foundation for endurance, why HRV and wearable data should be interpreted carefully, and how protocols like Norwegian 4x4 can improve performance when used in the right context. Through a blend of long-term training experience, research literacy, and practical coaching insight, Holmer helps listeners better understand how to train harder, recover smarter, and think more clearly about what actually improves cardiovascular fitness.
