  • What lactate actually is and why it’s a powerful signal for brain and muscle health
  • How high-intensity exercise triggers mitochondrial repair and neurogenesis

[CFMS SERIES] The Decline of Health in Italy and How to Stop It

By

On December 8, 2025

In The CrossFit Podcast

This marks the ninth episode of a special CrossFit Podcast collaboration with the CrossFit Medical Society. 

Italy once held one of the lowest obesity rates in the developed world, but that’s changing fast. CrossFit Country Manager and longtime affiliate owner Matteo Pozzati joins the show to talk about the cultural shift in Italy, the rise of chronic disease, and how CrossFit is stepping in to rebuild true health from the ground up.

Matteo shares his journey from coaching in Venice to teaching hospital workers how to move safely, leading Italy’s affiliate community, and fighting to preserve CrossFit’s identity amid the noise of mainstream fitness.

He and host Jocelyn Rylee discuss why elite coaching matters, how education is the bridge to better health, and what it’ll take to connect CrossFit affiliates and healthcare systems worldwide.

Topics Covered

  • The decline of the Mediterranean diet and rise of chronic disease in Italy
  • Bringing CrossFit methodology into hospitals and health care education
  • Building bridges between affiliates and medical professionals
  • Preserving CrossFit’s identity and elite coaching standards
  • Nutrition, culture, and the return to traditional food practices
  • The global challenge of connecting CrossFit to health systems

Community Highlight

For nearly two decades, Erin Richter has been fighting for health on the front lines — and refusing to give up.

She opened CrossFit Old School in Bowling Green, Kentucky, in 2008, staying there, as she put it, “because this was the area that needed it the most.”

Today, her affiliate serves kids as young as 3 and adults in their 80s. She partners with addiction recovery centers, supports people with disabilities, and helps those told they’d never squat again find their strength.

She’s built nonprofits, raised thousands for local causes, and worked with the state to bring CrossFit into public schools.

Erin doesn’t chase PRs or the spotlight, just impact. In a city dubbed the “Obesity Capital of the U.S.,” she’s quietly changing lives every day.
