Founders of Grit Tribe Fitness

Meet Karli & Devin Rorabaugh

We’re Karli and Devin—parents to two amazing boys and the founders of Grit Tribe Fitness.

Our passion for fitness has given us confidence, purpose, and a mission to help others become the strongest version of themselves.

We created Grit Tribe because we believe fitness is about more than workouts. It’s about resilience, community, and showing up for yourself even on the hard days. It's about surrounding yourself with people who encourage, support, and challenge you to grow.

At Grit Tribe, you're not just joining a gym—you’re joining a family. Whether you're starting your fitness journey or chasing new goals, we’re here to help you move better, feel stronger, and build confidence every step of the way.

Train Together. Grow Together.
