What Are the Limits of Sustainable Energy Expenditure?

The Norwegian Method Podcast

Olav joins David to discuss a recently published paper where Kristian was the subject. The paper, "Training volume and total energy expenditure of an Olympic and Ironman world champion: approaching the upper limits of human capabilities" looked to examine the upper limits of what energy expenditure humans can sustain long term with some findings that challenge the traditionally accepted upper limits.
