#1 | Roger Nitta | TRXTR Beginnings: Hard Lessons, Personal Growth, & Building a Unique Gym Culture

Mon, 21 Sep 2026 16:00:00 -0400

How does a kid raised on surfing, fishing, and BMX wipeouts end up building one of Hawaii's tightest martial arts families? In the premiere episode of TRXTR The Podcast, Roger Nitta shares the multi-generational journey behind TRXTR Studio.

Roger opens up about growing up by the beach, learning lessons the hard way through injuries and early sparring days, and how the jump from kickboxing to jiu-jitsu reshaped his approach to discipline, resilience, and growth. He gets honest about the leap from hobbyist to teacher, the struggle of launching a gym in the uncertainty of COVID, and why cross-training — and embracing losses as much as wins — built more than skills. It built a family.

If you train, teach, run a small business, or just love a story about betting on yourself, this one's for you.
