Why You're Losing Endurance Gains Every Single Week
From Brainwaves · 16:39
Show by Nina Valdez
Here's why your Sunday long run isn't building the endurance you think it is. Most people train endurance completely backwards. They go hard when they should go easy, skip the boring stuff that actually works, and wonder why their progress stalls after a few weeks. Nina Valdez breaks down the three energy systems your body uses and why understanding them changes everything about how you should train. What you'll discover: • Why 80% of elite athletes train at intensities that feel "too easy" • The specific heart rate zone that increases your mitochondria by 20% in 8 weeks • How your lactate threshold determines whether you hit the wall or keep going • Why most people's "moderate" pace actually sabotages their endurance gains Your body runs on three distinct energy systems, and each one needs different training to improve. The phosphocreatine system powers those first explosive 10 seconds. The glycolytic system kicks in from 10 seconds to 2 minutes. And your aerobic system handles everything longer than that. Here's what most people get wrong: they train in that middle zone between easy and hard, which doesn't optimize any of these systems. Zone 2 training feels almost boringly easy, but it's building the cellular machinery that actually makes you faster over distance. Nina explains how elite endurance athletes structure their training and why your lactate threshold matters more than your max heart rate for real-world performance.
