I have always found “deconstructionist” models appealing. For example, I liked the idea that you could “figure out” all the nutrients that you need and then build up a diet that provides the right mix of carbs, proteins, fats (with proper mix between omega-3 and omega-6 fatty acids), the right amounts of fiber, vitamins, minerals, and so on.
Then Michael Pollan came along and (in his book In Defense of Food) completely destroyed that idea. First of all, it’s an impossible problem to solve—the different nutrients interact in the body (and biome) in ways that are intractably complex, plus there are so many micro-nutrients as to make it computationally infeasible (even if we knew what all of them were, which we don’t). More to the point, though, it’s a completely unnecessary problem to solve: our bodies solve it for us, as long as we eat a diet of diverse foods and minimize our consumption of manufactured food-like substances.
I’m not saying this is new news. In fact, this is common knowledge—everybody said this, right from the start. What I’m saying is that, for reasons no doubt having to do with my personality and psychological makeup, I liked the deconstructionist model for analyzing and then constructing a plan for what to eat, despite what everybody said. For some reason, again having to do with my personality and psychological makeup, Michael Pollan’s explanation of how the whole deconstructionist model of designing a plan for eating was fundamentally flawed suddenly made it clear to me (in a way that any number of people—including my third grade health teacher and both my parents—had not managed to do).
All that seems relevant because—I recently realized—for years now I’ve been making the exact same mistake with movement. I’ve been trying to “figure out” an exercise regime that would keep me fit. If you click on the Fitness category over in the sidebar, or the “exercise” tag on this post, you’ll be linked to a long list of my posts on the topic, many of which describe my latest attempt to find the right mix of walking, running, bicycling, lifting, stretching, and taiji to build and maintain optimal levels of aerobic capacity, strength, and flexibility.
Then I ran into the work of Katy Bowman, whose explanations of why exercise is no substitute for movement clicked for me in just the same way, and for roughly the same reason: The problem is intractably complex, and anyway our bodies solve the problem for us—as long as we engage in an ample amount of diverse movement and minimize things like sitting in chairs and wearing bad shoes. (See her book Move Your DNA: Restore Your Health Through Natural Movement.)
Again, this is not really new news; I’m just late to the party because I like the idea of designing an exercise regime that covers all the necessary categories.
However, I think I have come around. Appealing as it is to me to design the perfect exercise regime and then tick off each box as I reach my target for the week, I pretty much have to admit that the whole thing is a fool’s errand. I’d be much better off spending that time walking, stretching, hanging, squatting, climbing, balancing, jumping, throwing, catching, and so on.
I’ll still run (because I enjoy it, probably due to the endocannabinoids, and because being able to run is useful), but I’ll spend a lot less time on things like figuring out how much I can safely add to my weekly mileage. I’ll just run as much as I feel like—while being careful to do so mindfully, and to pay attention to my body, so that enjoying running doesn’t entice me to run more than should.
Still not new news.
