Episode 28: Training Durability | What Sticks Around and What Disappears First

One of the athletes I work with, Robin Cummings, asked a deceptively simple question about heat training that opened up a much larger conversation: which training adaptations actually last, and which ones disappear the moment you stop training them? The answer reveals your body's efficient "last hired, first fired" approach to fitness —and changes how you should think about periodization.

In this coach-to-coach conversation, Robin, an elite cyclist and coach, and Chris break down the durability hierarchy that governs every training decision, from skills work that can last decades to altitude adaptations that vanish in two weeks. You'll learn why your body operates like a lazy but efficient accountant, maintaining only the adaptations it absolutely needs and dumping everything else the moment the metabolic cost gets too high.
