Marius Bakken: The Norwegian Method Is Built Around Your Muscles, Not Your Heart

Marius Bakken is a physician, a former professional runner and two-time Olympian with a 13:06 personal best for 5000 m, and the person who developed the training approach that later became known as the Norwegian method, since used by Jakob Ingebrigtsen, Andreas Almgren and many others. We cover why he sees the muscles rather than the heart and lungs as the real limiter, how double threshold works, how to find and control your threshold with or without a lactate meter, and how much of it carries over to triathlon.
