472: Will Ratelle on Giant Sets and the Art of Adaptive Training

More show notes at https://www.just-fly-sports.com/podcast-472 Today’s guest is Will “Hoss” Ratelle — former All-Big Sky linebacker turned strength and conditioning coach, with experience at the University of North Dakota, the NFL, and the CFL. Known for his intense, results-driven training style, Hoss blends his pro football background with evidence-based methods to build size, speed, and resilience in athletes. He’s also the creator of popular programs like “Hoss Concurrent” and a respected voice in the online performance space. Most fitness and training education tends to be rigid, centered around fixed sets, reps, heart rate zones, and prescribed loads and timing. While this structure has value, athletes eventually need to move beyond it and enter a more adaptive, natural rhythm of training. Sets and reps can serve as a starting point, but great coaching gives training a feel, one that fosters ownership, problem-solving, and deeper athlete engagement. On today’s episode, Will Ratelle shares practical strategies for building training protocols that allow for flexibility and athlete autonomy. He discusses how to keep athletes dialed in during strength and power work, while also diving into topics like hamstring rehab, velocity-based training, and more.
