Zona 2 NO basta: añade esto para mejorar tus mitocondrias

In this video, we discuss Zone 2, but with a crucial distinction: training in Zone 2 is fundamental for building an aerobic base, improving metabolic efficiency, and accumulating volume with minimal fatigue. However, Zone 2 alone isn't always enough if we want to optimize mitochondrial function and enhance performance. Zone 2 helps build a foundation: it improves oxidative capacity, promotes fat utilization, enhances lactate management, and allows for greater endurance. But short, high-intensity stimuli, properly dosed and strategically placed throughout the week, can also be a powerful signal for activating pathways related to PGC-1α, mitochondrial biogenesis, and improved energy efficiency. In the video, I explain: What Zone 2 actually is. Why many athletes push Zone 2 into Zone 3. How Zone 2 improves aerobic base. What the relationship is between mitochondria and performance. What role does PGC-1α play in training adaptation? Why can small, intense stimuli improve mitochondrial efficiency? How to combine Zone 2, strength, intensity, and recovery? Examples of typical weeks for cycling, running, and triathlon. How to apply Seiler's polarized zone model in practice. The key isn't choosing between Zone 2 or intensity. The key is knowing when to use each stimulus. Zone 2 builds the foundation. Well-dosed intensity fine-tunes the system. Strength supports the structure. Recovery consolidates the adaptation. And planning brings all the pieces together. If you train for cycling, running, or triathlon and want to improve your endurance, your mitochondria, and your performance without making the mistake of doing every ride too hard, this video will help you understand how to better organize your training.
