Episode 370: Hybrid Training Done Right: Building Strength & Endurance Without Killing Your Gains with Andreas Stobberup

In this episode of the Flex Diet Podcast, I sit down with Denmark-based coach and hybrid athlete Andreas Stobberup to talk about bridging serious strength training with high-level endurance performance. Andreas shares his journey from peaking around 250 lbs with a 405 bench and 600+ squat to dropping to 205 and completing a full Ironman in 9:52—while continuing to coach athletes across disciplines. We discuss the reality gap between amateur and elite performance, how influencer culture often strips context from training advice, and why fundamentals still win: training, nutrition, sleep, and measurable outputs. We break down common misunderstandings around Zone 2 training, why pros don’t train the way social media says they do, and how strength athletes can intelligently add conditioning without compromising lifting. We also cover VO₂ max development, microdosing cardio, output-based tracking (times, power, lactate), and how to think about HRV and wearable data in context. If you’re interested in hybrid training, improving conditioning without sacrificing muscle, or understanding how to measure what actually matters, this one is packed with practical insight.
