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.

Don’t Let Menopause Slow Your Metabolism: How to Lift, Sprint Hard & Fuel w/ Dr. Stacy Sims
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Menopause doesn't have to mean a slower metabolism, stubborn belly fat, or feeling like your body betrayed you. In this interview Dr. Stacy Sims—world-renowned exercise physiologist, nutrition scientist, and author of ROAR and Next Level—breaks down exactly why traditional advice (endless Zone 2 cardio, fasting, calorie restriction) backfires for women in perimenopause and menopause... and what actually works to rev your metabolism, build resilient strength, and thrive.
We dive deep into:
-Why sprints and heavy lifting (low reps, high intensity) create powerful metabolic signaling
-The truth about fueling: More protein + carbs (not less), nutrient timing, and why "calories in, calories out" is outdated for women
-How hormone shifts affect insulin sensitivity, glucose use, visceral fat, and brain health...and how to counter them with smart training
-Shifting from "loss" to "gain": Build muscle, power, and metabolic health instead of shrinking or slowing down
-Practical tips: Less volume/more quality, recovery, mobility, creatine, and mindset shifts for midlife resilience
If you're a woman 40+ feeling the "rules changed" and wondering why your old routines aren't delivering results anymore, this episode is your reset. Dr. Sims empowers you to take up space, push hard, and feel stronger than ever.
