The Fitzness Show

Fitz Koehler talks with Michael Jones, who lost 100 pounds and built elite fitness—long before Parkinson’s ever entered the picture.

When it did, that fitness changed everything. Because he was so strong, capable, and conditioned, Michael qualified for a trial procedure that has nearly shut down his tremors and muscle tightness—something he likely wouldn’t have been eligible for otherwise.

This is the payoff of doing the work befor...

Marathon DRAMA! Fitz Koehler and Rudy Novotny break down the wildest race-day chaos making headlines — elite runners sent the wrong way in Atlanta, finish-line interference in L.A., and a race official in China literally stopping the winner. Yep… you can’t make this stuff up.

They dive into how lead cars, course marshals, and over-excited spectators turned big races upside down, what it cost the athletes emotionally and fin...

Fitz Koehler fires through listener questions on training after hernia surgery, the truth about midlife weight gain (it’s not just menopause), and why nutrition, sleep, and discipline still decide everything. She shares how to fuel early workouts, keep muscle as you age, rebuild strength after cancer one percent at a time, and drop fat while building muscle for real, visible abs.

Plus: easy at-home and in-bed exercises, behi...

On top of answering listener questions, Fitz uncovers a lingering medical mystery (with a lesson learned the hard way), shares the slightly creepy vibes of an oncology checkup, and then cranks the volume back up for the upcoming Jacksonville Icemen’s Whiteout for Cancer night.
