Exercise Expert Reveals: The One Thing Blocking Women From Burning Fat Faster
Zone two has been sold to you as the gold standard for mitochondrial health, fat burning, and longevity. But what if it was built on culture, not science.
In this episode, I sit down with Kristi Storoschuk, a PhD researcher whose work is challenging some of the biggest claims in the exercise world right now. We break down why zone two training lacks the scientific evidence everyone assumes it has, why higher intensity zones three and four are actually more potent for mitochondrial adaptation, and why the 80/20 training split from elite athletes was never designed for someone exercising four days a week.
We also get into why fasting doesn't activate the same cellular pathways in humans as it does in rodents, why cortisol from exercise is not the same as chronic stress, the truth about fasted exercise for women, and what lactate actually tells us about our metabolic health. Kristi also shares her current research in collaboration with Dr. Andy Galpin and Dr. Tommy Wood on whether lactate threshold can serve as a non-invasive proxy for mitochondrial content. This conversation will completely change how you think about every cardio session you've ever done.
