Fitz Koehler

Fitz Koehler, M.S.E.S.S., is a dynamic force in the fitness industry—gracing stages worldwide, firing up finish lines as America’s Noisiest Race Announcer, and calling out excuses wherever they hide. With a master’s degree in Exercise and Sport Sciences from the University of Florida, Fitz fuses real science with humor, heart, and unapologetic bossiness. Her no-nonsense, get-it-done approach feels like a pep talk from your most fun, brutally honest friend—the one who’ll hand you a water bottle, crack a joke, and tell you to stop whining and start winning.

Fitz has energized audiences for some of the world’s most respected brands and organizations—including Disney, Oakley, Office Depot, and the American Cancer Society—delivering high-impact keynotes that inspire action and lasting change. She’s also a familiar face on national and regional television, appearing hundreds of times to share her practical, real-world advice on fitness, weight loss, and living well.

She’s the creator of The Morning Mile, a before-school walking and running program now thriving in more than 400 schools worldwide, helping kids and families start their days strong and active.

Her newest book, You. Supercharged! The Exact Formula for Fitness, Weight Loss, and Longevity, gives adults the blueprint to take control of their bodies and their lives. It’s a smart, science-based, and refreshingly honest guide to building strength, losing weight, boosting energy, and creating sustainable habits that lead to a longer, happier, more powerful life.

Fitz’s resilience runs deep. After enduring 15 months of the “treatment triathlon”—chemotherapy, radiation, and surgeries—she conquered cancer and came back stronger than ever. That life-altering experience inspired her Healthy Cancer Comeback Series, designed to help patients and survivors regain strength, confidence, and joy through fitness.

Through her hit podcast The Fitzness Show, her impactful books, and her electric energy on race stages across America, Fitz continues her mission to help people live better, longer, and louder. With her, fitness isn’t punishment—it’s power, fun, and freedom. Visit Fitzness.com and @Fitzness on all socials for a jolt of energy!
