Inside VO₂ Max Testing with Sean Kinane: The Data That Drives Better Training

In this episode, I sit down in the studio with Sean Kinane from Health Matters for a deep dive into the science of performance testing. With over 13 years of experience and more VO₂ max tests conducted than anyone else in the world, Sean has built an unparalleled understanding of how the body responds to exercise under the microscope. Together we unpack the methodology behind VO₂ max and metabolic testing, how the tests actually work and what the numbers truly mean. We explore the key data points these assessments reveal from aerobic capacity and substrate utilisation to training zones and how athletes, coaches and everyday exercisers can use this information to train smarter, not just harder. If you've ever wondered what happens in a lab test, how accurate your training zones really are, or how metabolic data can transform your performance and health, this conversation breaks it all down in a practical, accessible way.
