In this episode, Steve Kwan is joined by Rosie Miller to explore the concept of the “tryhard hobbyist” in Jiu-Jitsu: someone who trains seriously and with intention, even if they don’t pursue the sport professionally. Rosie, a brown belt out of Atos HQ and founder of The Grappler’s Lab, shares her journey of evolving goals, identity, and self-worth within the sport. Together, they discuss the emotional and mental challenges hobbyists face, including impostor syndrome, burnout, risk management, and the struggle to balance ambition with sustainability. Rosie offers a values-based framework to help practitioners define their goals, align training with life priorities, and find long-term fulfillment in Jiu-Jitsu, regardless of competitive aspirations.
