Rosie Miller (@rosierollz) joins us for one of our favorite conversations yet. We dive into her journey from dance and competitive boxing to becoming one of the most respected competitors, coaches, and educators in jiu-jitsu, and how each chapter shaped the way she approaches learning, teaching, and competing today.

We talk about why fundamentals never stop mattering, how concept-based training and the Constraints-Led Approach (CLA) are changing the way people learn jiu-jitsu, and why simply collecting techniques isn’t enough to build a game that actually works. Rosie also shares her thoughts on cross-training, gym culture, the gi vs. no-gi conversation, and how different training environments have influenced her development.

One of the biggest takeaways from this episode is Rosie’s perspective on helping athletes become problem-solvers instead of instruction followers. We discuss creativity on the mats, overcoming plateaus, coaching kids and adults differently, and creating an environment where people can develop their own style instead of becoming copies of their coaches.

Of course, we also get into a little bit of Rosie’s personal story. We talk about how a difficult season in her life led her to jiu-jitsu, what kept her coming back, and why she’s so passionate about making the sport more approachable for everyone.

Whether you’re a competitor chasing gold, a coach trying to develop better athletes, or someone just looking to improve your understanding of jiu-jitsu, this episode is packed with insights you’ll be thinking about long after it’s over.

In this episode, we sit down with 15-year-old jiu jitsu phenom Connor Stallmer, a rising star already making waves on the biggest grappling stages.

Connor shares how he got started in the sport at just five years old, the family support that helped shape his path, and how competition turned jiu jitsu into a lifelong passion. We dig into his journey from youth tournaments to adult divisions, his evolution from gi to no gi, and the mindset that’s helped him stay focused while so many others fell away.

We also talk about his breakout Who’s Number One debut, his approach to leg locks, the grind of training at Simple Man, and what it takes to compete at an elite level as a teenager.

If you love jiu-jitsu, high-level competition, and hearing from the next generation of grappling talent, this one’s for you.

In this episode, we sit down with the founder of Standard Jiu Jitsu and ecological approach advocate Greg Souders for a deep dive into the constraints-led approach to training and skill acquisition. Greg breaks down why so many coaches struggle to let go of step-by-step instruction, how to design training that actually creates learning, and why the athlete’s responsibility matters just as much as the coach’s.

The conversation moves from the theory of CLA into practical coaching insights for both adults and kids, including how to adjust constraints, how intensity affects learning, and why not every athlete needs the same environment to improve. We also dig into the differences between beginner and advanced rooms, training for competition, and how to prepare athletes for the uncertainty of high-level opponents without trying to over-control the outcome.

The episode also explores broader questions around youth sports, long-term development, and the role of desire, maturity, and experience in becoming an "elite" athlete. Along the way, Greg shares thoughtful perspectives on coaching culture, the limits of language, and how to create meaningful learning experiences that keep athletes engaged and improving.

If you’re interested in jiu-jitsu, coaching, or the science behind how people actually learn, this conversation is full of practical ideas and big-picture insight.
