When you join Redefining Strength, you join a team that’s in your corner from day one.

Meet The Founder

Hi I’m Cori Lefkowith!

I started Redefining Strength in 2014 as an in-person training facility…built from the ground up around one belief: that real coaching, real relationships, and real results only happen when someone is truly invested in you. That belief is still the foundation of everything we do today.

My own journey into coaching wasn’t a straight line. I learned the hard way what happens when you chase results through extremes…burnout, a broken relationship with food, and the frustrating cycle of doing everything “right” and still feeling like you’re failing. I knew there had to be a better way. Building that better way became my life’s work.

Over the past decade, we’ve coached more than 10,000 women through our 1-on-1 program and reached millions more through my podcast, YouTube channel, and The STRONG System. But the thing I’m most proud of isn’t any number it’s the team we’ve built to make it possible.

Every coach at Redefining Strength was hand-selected for one reason: they are the best at what they do. Experienced, credentialed, and deeply committed…they bring their own expertise, empathy, and lived experience to every client they work with. When you join RS, you’re not getting a program. You’re getting a whole team of exceptional people in your corner from day one.
