▶ Pillar 4: The Metabolic Reserve (this article)
In the video, I talked about the decision to stop drinking — not as a lifestyle statement, but as a biological one. After reading the data on what alcohol does to the post-exercise mitochondrial biogenesis signal, the choice became straightforward. That data is in this article, alongside the full metabolic protocol: how to time your training and nutrition to maximize the cellular adaptation that makes every other reserve possible.
The metabolic reserve is not one system among four. It is the energy infrastructure that the cardiovascular, musculoskeletal, and cognitive reserves all run on. Get this one right, and the others compound. Neglect it, and the others degrade — regardless of how much time you spend on the bike.
