The Aerobic Edge

In this episode I sit down with Professor Paul Laursen — sport scientist, co-author of Science and Application of High-Intensity Interval Training, and co-founder of Athletica — to break down the science of endurance in plain language. From mitochondria and fat-burning to HIIT, the neuromuscular system, nutrition, recovery and HRV, we turn the biology of...

In this episode of The Aerobic Edge, coach John Starrett ("The Stable Master") returns for a deep dive into the sub-3 marathon — a magical barrier for many runners. Since 2017, John has coached a staggering 962 runners to sub-3 and 274 to sub-2:30, all online. We unpack what it actually takes to break that...

Lawrence van Lingen is a sports chiropractor and movement specialist. Described by Triathlete Magazine as the genius of running, he has over 25 years of experience working with world-class athletes including Jan Frodeno, Taylor Knibb, and Flora Duffy. In this episode we talk about why most running injuries keep coming back, what fascia actually is and...

John Starrett is an experienced endurance coach with over 40 years in the sport. He has coached more than 900 runners to a sub-3 hour marathon and has guided male and female athletes to the US Olympic Marathon Trials. He is also known as The Stable Master. This is John's second appearance on The Aerobic...

Scott Johnston is one of the most respected endurance coaches in the world. As founder of Evoke Endurance and co-author of Training for the Uphill Athlete, he has coached athletes across skiing, mountaineering, trail running and road running. In 2025, both the men's and women's UTMB champions — Tom Evans and Ruth Croft — were...

In this episode, Joost sits down again with coach John Starrett to dive into one of the most overlooked phases in endurance training: bridge training. After building a strong aerobic base through the foundation, pre-super base, and super base phases, many runners jump too quickly into race-specific work. Bridge training fills that gap—safely introducing intensity,...

Most runners assume that logging more miles automatically makes them better fat burners. The science says otherwise. In this episode, Joost sits down with New Zealand-based sports dietitian and researcher Mikki Williden (PhD, public health) to unpack one of the most misunderstood topics in endurance sports: metabolic flexibility. Mikki has a 2:55 marathon PB, has...

Most runners either skip strength training or do it completely wrong. In this episode, Joost breaks down how just 5 to 10 minutes a day makes you a stronger, more durable runner — no gym, no heavy weights. Just a minimalist routine that improves your running economy without sabotaging your recovery. Why heavy lifting can...

Most runners shuffle. Short stride, low heel lift, zero power. It's not laziness — it's your glutes being completely switched off. And the frustrating part? Adding more miles or speed work just reinforces the problem. In this episode we go deep on gluteal amnesia, the neuroscience of running mechanics, and the two tools — hill...
