Understanding Cardio Zones

The discussion revolves around the different cardio zones, specifically focusing on zones one through three. Zone one represents easy aerobic movement, while zone two involves a steady level of cardio that can enhance mitochondrial health and improve metabolic flexibility. Zone three is described as requiring more effort, utilizing glucose as a fuel source, but may not yield the same long-term benefits as zone two. Understanding these zones helps individuals tailor their workouts to maximize health benefits and performance.
