Meet Danni Duncan- Fitz's Australian Fitness-Preaching Cancer-Crushing Twin

from The Fitzness Show · host Fitz Koehler

Is Danni Duncan the Australian Fitz… or is Fitz the American Danni? Either way, this conversation crackles. From teaching fitness to staring down colon cancer, Danni shares how strength training, tiny daily wins, and unapologetic tough love carried her through diagnosis, chemo, and the climb back to running, motherhood, and real life with four kids. Nothing is sugar-coated. Expect straight talk on colonoscopies, processed meats, excuses we tell ourselves, and what it actually takes to keep moving when life gets heavy. If you need proof that hard things are survivable—and motivation to stop negotiating with yourself—this episode will light the match.
