Clearly, something about John’s question triggered me. It’s not that I was a passionate devotee of strength training over endurance, or vice versa; I’d done plenty of both. I was reacting to the binary nature of his question. In case you haven’t figured it out by now, I’m not fond of the way we reduce these complex, nuanced, vitally important questions down to simple either-ors. Cardio or weights? Low-carb or plant-based? Olive oil or beef tallow? I don’t know. Must we really take sides?
