Master Modern Pilates

Four days. One world-renowned master trainer. A certification that opens doors.

This isn't just a certification—it's your entry into an elevated approach to movement that's transforming modern reformer studios worldwide.

The reformer fitness industry is exploding, but here's the thing: not all training is created equal. While others teach movements, Jonathan Nguyen teaches mastery. While others focus on the machine, Jonathan focuses on the human.


La Forme didn't just choose any trainer for our inaugural certification program. We chose the master trainer who's trained instructors across the world, revolutionized modern reformer Pilates methodology, and built a reputation for creating instructors who don't just teach - they transform lives.

Join fitness industry legend Jonathan Nguyen for an intensive Level 1 Megacore Reformer certification at La Forme—St. Louis's most thoughtfully designed mega reformer studio.

Get to Know Jonathan

In November 2021, Jonathan made a decision that changed everything: he traded his medical career to teach the evolution of modern Pilates. What started as a leap of faith has become a global movement.

The Numbers Don't Lie:

  • 30+ classes taught weekly (when he's not traveling the world)

  • 40+ studios trained across 6 countries in just 3 years

  • Thousands of instructors certified in his methodology

  • Multiple reformer specializations: Xformer, Megacore, Lagree Megaformer, and more

But here's what makes Jonathan different: He doesn't just teach exercises—he teaches the why behind every movement. His E.S.C.P. method (Exercise. Strength. Core. Pilates.) isn't about following trends; it's about understanding the science of transformation.

"My mission is to craft each session to challenge clients, offering adaptable variations and intensifications while providing knowledge and unforgettable experiences. I want to empower instructors with the tools to navigate their fitness journey, recognizing their inherent strength and limitless potential." — Jonathan Nguyen
