Do Training Zones Actually Matter? (with Aitor Altuna)
Everyone knows what Zone 2 is. Or do we? In this episode of the Nduranz Podcast, Alex Rhodes and Dr. Tim Podlogar are joined by Aitor Altuna, cyclist and PhD researcher at the University of Exeter, to make sense of training zones and what they actually mean in practice. They discuss why Zone 2 can mean different things depending on the model you use, the difference between polarized and pyramidal training, why perceived effort still matters even when you have power, pace or heart rate data, and how nutrition should support the purpose of each session. Youβll also hear why making every workout harder isnβt necessarily better, how low-intensity training helps you accumulate more sustainable training load, and what amateur athletes commonly get wrong when structuring their week.
