Robert Rettmann: How Crunch Fitness Trains World-Class Coaches and Scales Culture

Robert Rettmann, VP of Education at Crunch Fitness, takes us inside the playbook that helped his franchise group grow from 28 to 86 clubs within a network of 500 plus locations. We trace his journey from NASM and PTA Global to building a modern education engine at Crunch with three day training camps, an in house LMS, and a head coach model that keeps learning alive on the gym floor. Rob shares how they turn new hires into confident coaches, why sales, science, and service belong in the same sentence, and how simple habit changes beat extreme programs for long term results. We dig into culture at scale, the importance of a real hello at the front desk, and a new tech platform that gives clients full visibility on sessions, logs, scheduling, and ratings while helping managers coach from live data. We close with trends he is betting on, why in person still wins, and practical advice for any trainer who wants to become indispensable.
