Zonas de entrenamiento II zona 1

In this episode of Let's Talk About Exercise Physiology, we explore what happens in the human body when we train in Zone 1, a gentle yet fundamental intensity for health and performance. We analyze the cardiovascular, respiratory, and metabolic responses that occur during continuous, low-intensity exercise, including adaptations in the heart, vascular function, fat utilization, and mitochondrial development. We also discuss why this zone is key for building a solid aerobic base, improving cardiometabolic health, and promoting recovery, but also why training exclusively in Zone 1 can limit certain adaptations related to VO₂ max, power, and competitive performance. This episode helps you understand that often, training at a gentler intensity can be exactly what your body needs to adapt more effectively. Instagram: @henryleon_md https://henryleonmd.com/
