  1. Episode 4 : Building a Training Week That Works in Real Life, Zone-2, Controlled Intensity, and the 4×4

    Episode 4 : Building a Training Week That Works in Real Life, Zone-2, Controlled Intensity, and the 4×4

    January usually invites people to build the “perfect” training plan — the one that looks incredible on paper but collapses the moment real life enters the room. Episode 4 of Endure Prime takes a different approach. Instead of chasing fantasy schedules and unrealistic expectations, we build something durable, flexible, and deeply effective: a training week that works for beginners, masters athletes, marathoners, speed-seekers, and anyone who just wants to feel good in their own body. In this episode, we break down the two anchor workouts every athlete should have — the Zone-2 engine-builder and the controlled-intensity session — and show you exactly how they form the repeatable foundation for any goal. Then we zoom out into the long day, the easy-support day, and how to add third, fourth, fifth, and sixth training days without tipping into fatigue or chaos. We also explore the iconic 4×4 interval, why Norwegian researchers Jan Helgerud and Jan Hoff made it famous, and how to execute it correctly whether you train by feel, heart rate, or lactate. Whether you're building toward a race, rebuilding your fitness after a long break, or navigating midlife with a smarter lens on training load, Episode 4 shows you how to shape a week that holds up — not just in January, but all year. This episode also includes a segment for masters athletes, plus the introduction of the Sub-20 Project, a long-term journey to running a sub-20-minute 5K at age 57+ — an honest, real-life case study in smart, sustainable training.

  2. Episode 3: Endurance Begins with Awareness — The Diaphragm, Breath, Fatigue & the Vagus Nerve

    Episode 3: Endurance Begins with Awareness — The Diaphragm, Breath, Fatigue & the Vagus Nerve

    Most endurance athletes learn to track their mileage, pace, and heart rate — but very few ever learn to work with the one system that shapes all of it: the nervous system. This episode is an invitation to slow down, tune in, and understand your body in a way most training plans never teach. We begin with the three types of tired: • Physical fatigue — the simple, earned kind • Mental fatigue — the foggy, overloaded kind • Life-load fatigue — the heavy, often invisible kind Each one feels different in the body, requires a different approach, and influences how hard or easy a workout should be. Once you can recognize your fatigue type, training stops being a battle and becomes a conversation. Then we explore nasal breathing — not as a trend, but as a practical tool that widens blood vessels, improves oxygen delivery through nitric oxide, and naturally keeps the body in the sustainable aerobic zone. We break down how nasal breathing activates the diaphragm, shapes your pacing, and quietly nudges the vagus nerve — the nerve that regulates calm, recovery, digestion, heart rate, and emotional steadiness. From there, we look at the subtle early signals most athletes miss long before fatigue hits: shifting breath, collapsing posture, noisy thoughts, mismatched effort, and emotional tone. When you learn to read these whispers, you avoid overtraining and build a training rhythm that fits real life — not the fantasy life where everything goes to plan. Whether you're running, cycling, walking, or simply trying to take care of your health during a busy December, this episode gives you a way of understanding endurance that is gentler, wiser, and far more sustainable.

    Episode 2 — Smart Running in the Shady Months

    In this episode of Endure Prime, Bjorn-Ivar takes you inside the reality of winter training — where darkness, weather, schedules, and everyday life collide. Through stories from filming running routes in Oslo, he explores why indoor training isn’t “cheating,” why consistency is the real engine of endurance, and how small adjustments can transform your motivation through the colder months. You’ll hear how to train in the “real-life lane,” where work, family and energy levels don’t always cooperate — and why removing obstacles is more powerful than chasing motivation. Bjorn-Ivar also breaks down the mental boost of running in new environments, the traps that make people stop training, and how simple rhythms can outlast even the toughest seasons. This episode finishes with a practical deep-dive into Zone-2 training: what it is, why it matters, and how to integrate it into a real week whether you’re new, returning, or experienced. In this episode: Oslo stories + why novelty boosts motivationIndoor training as strategy (not shortcuts)The “real-life training lane”Why people stop — and how to avoid itMid-life adaptation (for all ages)A simple, human guide to effective Zone-2 training Whether you train once a week or six, Episode 2 will help you build endurance that fits real life — even when the world outside turns cold and dark.
