HRV, Metabolism & Training Readiness Explained (What Wearables Miss) with Marco Altini

Heart Rate Variability has gone mainstream. Rings, watches, readiness scores, green lights, red lights: everywhere. But are endurance athletes actually getting better because of it? In this episode of Mad Science Meets Real Life, Alan Couzens and Inaki de la Parra sit down with Marco Altini, founder of HRV4Training, coach, researcher, and long-time skeptic of simplistic wearable “scores”. The goal is simple: Strip HRV back to what it really is: a window into your stress response, not a command to train harder or easier. #HRV #TrainingReadiness #EnduranceTraining #MetabolicHealth #MarcoAltini #AlanCouzens #InakiDeLaParra #SportsScience #WearableTech #Recovery
