This is the companion post for the presentation that I did of the same name.

I’ve written about these topics fairly extensively; if you want the longer version you can find it here. The video is intended to be more approachable and more practical than the ones I’ve done in the past and bring in some additional information about different muscle fiber types, their use in different kinds of sports, and how that might impact your fueling strategy.

The data for the graph came from this study:
