In this podcast Maddy talks to James Spragg, a cycling coach and physiologist, about energy systems. James talks through the different energy systems, the relationship between intensity and energy system contribution, takes a deep dive into the aerobic energy system and how to train it effectively, and talks about profiling our energy systems in order to inform training.
