Zone 2 cardio is the foundational aerobic pacing that fuels mitochondrial efficiency, metabolic flexibility, and cardiorespiratory health. By maintaining a steady, conversational pace where cellular energy demands are met primarily through fat oxidation, adults over 45 can build an expansive aerobic base that directly drives up VO2 Max—one of the single most powerful predictors of healthy aging and long-term vitality. Explore evidence-informed habits and practical training guides below.
