Why Cardio Alone Won't Save You in Perimenopause — And What Will @DrStephanieEstima

Uploaded May 2026 | Updated September 2026, 2 weeks ago

Zone 2 cardio is wonderful. But it only builds gears one and two.

And if you never train the higher gears — the rapid, glycolytic, explosive capacity your body is capable of — you are quietly undertrained in ways that matter more than you think: glucose disposal after meals, fall prevention in your 70s, nervous system resilience, power output, body trust.

Dr. Stephanie Estima makes the case for why metabolic health is really about flexibility — the ability to switch fuels, produce energy fast, handle spikes in demand. And why intensity, appropriately dosed, is not the enemy. Avoiding it is.

This clip covers:
- What metabolic flexibility actually means
- Why glycolytic capacity matters for insulin sensitivity
- The cortisol narrative that's making women train less effectively
- How to dose HIIT as a beginner, intermediate, and advanced trainee
- Why heart rate recovery between intervals is the key metric
