Have you heard this before…keep your easy days easy and your hard days hard? Well, is there a physiologic basis for not spending much time training in the middle? Is there a downside to training in the middle? Tempo runs are supposed to be important, aren’t they, and they’re in the middle? Exercise bio-energeticists, such as myself, describe three zones or domains of exercise intensity based on the ratio of oxygen consumption to work rate and the sustainability of the intensity. These three domains are termed: moderate, heavy, and severe. In this episode, you’ll learn some of the physiologic bases for choosing how much time to spend in each zone.
