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.

5 Reasons You Fail At 30-Day Challenges (Ft. Dr. Caroline Leaf)
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Ever finished a challenge only to slide right back into old habits? You're not lazy, and you don't lack willpower...you've just been repeating a pattern no one taught you how to break.
In this episode, I'm pulling back the curtain on the five mistakes that kept me restarting every 21 or 30 days: going in without an exit strategy, blindly following a plan instead of understanding why it works, ignoring the mind-body connection, believing it has to feel hard to count, and cherry-picking pieces of a system instead of trusting the whole thing.
Then I'm joined by neuroscientist Dr. Caroline Leaf, who breaks down the science behind why real change takes about 63 days—three cycles of 21and why most challenges only ever get you through the first phase. We dig into the difference between the mind and the brain, how the labels you put on yourself quietly run the show, and her five-step Neurocycle for rewiring the patterns that keep tripping you up.
If you're tired of starting over, this one will help you understand what's actually happening underneath the cycle and how to finally step off it.
In this episode:
- Why a challenge should be an "exit ramp," not a finish line
- The hidden mindsets that sabotage habits before they stick
- How your mind creates meaning (and why that's good news)
- Dr. Leaf's Neurocycle, step by step
- Honoring your past without living in it
