What separates a good coach from a great one? Sometimes, it comes down to the words they use, the systems they build, and their ability to connect with athletes.

In this episode, Dr Nick Winkelman joins us to reflect on his journey from helping develop EXOS into a globally recognized coaching education platform to leading athletic performance within Irish Rugby.

Nick shares how the EXOS training philosophy helped reshape approaches to movement preparation, why effective performance systems need both consistency and flexibility, and how Irish Rugby has successfully connected its provincial teams through shared standards, data, and collaboration.

The conversation then turns to Nick's work on the language of coaching, exploring how external cues, analogies, and carefully chosen words can influence movement and skill development. He explains why giving athletes more information isn't always better, how to recognize when a coaching cue is working, and why understanding the person behind the athlete is essential to effective communication.

What does it actually take to become a faster HYROX athlete?

Dr Charlie Davids joins us to explore the physiological demands of HYROX, combining his research in muscle physiology and strength training with his own experience competing in the sport.

The conversation examines why aerobic capacity provides the foundation for HYROX performance, how lactate threshold and critical speed influence race pacing, and why muscular endurance may become more important than maximal strength once athletes reach a sufficient strength level.

Charlie also shares findings from his research linking running speed at the second lactate threshold to HYROX performance, alongside practical approaches to periodization, station technique, and training under fatigue.

The episode also explores blood flow restriction training and its potential to improve muscular endurance and aerobic adaptations, while highlighting where more research is still needed to establish meaningful performance benefits.

Developing a footballer is about more than preparing them for the next match. It means understanding what that individual player needs to keep training, developing, and ultimately reach their potential.

Mattia Modonutti joins us to share his approach to player development and performance within elite football. Rather than treating performance as a collection of separate disciplines and datasets, Mattia explains why the real value comes from getting coaches, strength and conditioning staff, nutritionists, medical teams, and mental performance practitioners around the same table to build a richer
understanding of the athlete.

The conversation explores training continuity, individualizing load within a team environment, balancing match demands with long term physical development, and the difference between simply using a physical capacity during football and actually training it. Mattia also shares how his thinking has evolved as he moved from hands on coaching into performance leadership and why being evidence informed means combining research with experience, practitioner expertise, and athlete feedback.
