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.
