Redefining Strength Podcast
You train hard. You try to eat well. You stay disciplined. And yet progress slows. Energy drops. Fat loss stalls.
The Redefining Strength Podcast is for women who work hard on their health… but still feel like their body isn’t responding the way it used to.
Hosted by Cori Lefkowith, founder of Redefining Strength, this show helps you understand what’s actually happening inside your body — and what to do about it.
Cori is the creator of the STRONG System, used by over 10,000 women around the world to transform their bodies and build results that last.
Through real coaching insights and conversations with leading experts in women’s health, metabolism, and behavior change...each episode breaks down the science in a way that actually applies to real life.
Because the answer isn’t working harder. It’s learning how to work smarter so your effort finally creates the strength, energy, and confidence you’ve been chasing.
If you’re ready to stop starting over and start building a body you can count on, this podcast will help you get there.

Metabolism, Cortisol & Hormones: What Women Get Wrong | Dr. Aviva Romm
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Most women are tracking everything...their sleep, their stress, their steps, their food...and still feel exhausted, overwhelmed, and like their body is working against them. Yale-trained MD and New York Times bestselling author Dr. Aviva Romm says the problem isn't your data. It's that you've stopped trusting yourself.
In this episode, Dr. Romm breaks down why metabolic flexibility —not more optimization — is the real key to lasting health, strong hormones, and aging well as a woman. We get into why cortisol isn't the enemy (and what actually happens when you chronically suppress it), how your menstrual cycle should be shaping your training, and why high-performing women are often the last ones to listen to what their body is telling them.
We also talk about the quiet strength in setting boundaries, why willpower isn't a character trait, and how to stop "shoulding" on yourself and actually build habits that stick.
If you've ever pushed through exhaustion, ignored your body's signals, or wondered why doing more keeps leaving you feeling like less — this one's for you.
Topics covered:
- What metabolic flexibility actually means and why it matters for women
- The truth about cortisol and why demonizing it is making things worse
- How to train smarter across your cycle
- Why your fitness tracker might be working against you
- Boundaries, burnout, and the real cost of always saying yes
- How to build habits from want-to instead of should
