The TRX Podcast

In this episode, we’re joined by Sam Theyers, Commercial Sales Director at Wattbike, to explore how data, performance testing, and smart benchmarking are reshaping the fitness industry.
Sam shares insights from his journey through the sector — from gym floors to leadership roles — and breaks down how fitness testing can drive member engagement, improve personal training uptake, and fuel real business growth. We discuss the role of objective data in client motivation, common mistakes facilities make with onboarding, and why gyms that embrace performance metrics are ahead of the curve.
If you’re a coach, club owner, or fitness leader, this conversation will give you practical ideas and strategic insight on how to better serve your members through data-driven training.

In this episode:
– The origins of ROCUP and its mission
– How running builds connection and confidence
– The role of leadership and vulnerability in community fitness
