Lift by Daniel Kunitz

My brother shared this comic with me a while back. I think it captures something—something about CrossFit, but also about how people react to anyone who’s “really into” anything.I’m not a crossfitter, but my expanding interests in fitness and movement have produced similarly horrified reactions to the prospect of having to engage with me on the topic—less frantic only because people are not literally trapped in an elevator with me.

I bring this up because the recent book Lift, by Daniel Kunitz, can be read as a love song to CrossFit (although he has done a pretty good job of discreetly tucking away most of the CrossFit stuff near the end of the book).

The book is more than just one thing, and even more than a love song to CrossFit it’s a fascinating cultural history of fitness.

Kunitz uses the term New Frontier Fitness to refer to the whole emerging cluster of practices centered around the idea of “functional” fitness: CrossFit, MovNat, Parkour, AcroYoga, obstacle course racing, and any number of gymnastic and calisthenic exercise practices. Kunitz doesn’t mention Katy Bowman’s work, but it obviously fits in as well.

Doryphoros MAN Napoli Inv6011-2A key thesis of the book is that the motivating genius of New Frontier Fitness is not without precedent: It springs directly from ancient Greek ideals of fitness, and he references both ancient Greek representations of a fit body (such as the Doryphoros sculpture) and statements by ancient Greeks not unlike Georges Hébert’s admonition “Be strong to be useful.”

This cluster of ideas—in particular that fitness was a moral and social obligation, but also that functional fitness produces a beautiful body as a side-effect (rather than as a goal)—largely disappeared after the Greeks, except in tiny subcultures such as the military. It has only reemerged in the past few years as the various things that Kunitz refers to as New Frontier Fitness.

In between—and the 2000-year history of this makes up of the center of Kunitz’s book—there were many things that were not this particular tradition of functional fitness, but instead were aimed at producing a particular type of body (body-building, aerobics, etc.)

It’s impossible for me to talk about Daniel Kunitz’s Lift without comparing it to another book—Christopher McDougall’s Natural Born Heroes. They are similar in at least two ways. First, they both compare modern fitness culture to that of the ancient Greeks. Second, they both appear to have been written just for me.

A third book that I read recently but haven’t written about is Spark, by John J. Ratey, which overlaps in the sense that all talk about intensity as a key aspect of exercise to produce functional fitness. (If all you’re interested in is appearance and body composition, you can get most of the way there with a diligent application of low-intensity exercise, but some amount of intensity is highly beneficial for functionality and brain health.)

All three books are worth reading.

Experimenting with low-carb

I’ve resisted low-carb eating for a long time, even as the evidence has increased that high-carb diets are terrible for us.

Via Christopher McDougal’s book Natural Born Heroes, I discovered Phil Maffetone and his two-week test, which caught my eye.

I’m generally very healthy and feel great, but I do have a few health issues—and there seems to be at least some evidence that a low-carb diet might help all of them. The point of the two-week test is to test exactly that: If you go very low-carb, does it make things better? If not, then you’re done—excess carbs are probably not your problem. If it does make things better, then you follow up the two-week test by gradually experimenting with adding carbs from various sources in various amounts, and figure out how much (and which kinds) of carbs you can consume without problem.

The things I’m hoping a low-carb diet might help are these:

  1. Allergies. Over the last twenty years I’ve gone from claiming that I don’t have allergies, to admitting that I get sniffles for a couple of weeks in the spring and the fall, to needing to take both Claritin and Nasacort daily. There’s some reason to believe that a low-carb diet might reduce inflammation. If true, that might ease my allergy symptoms (besides improving my general health), and might mean that I could eliminate those drugs, or perhaps just reduce them from constant to occasional.
  2. High blood pressure. My blood pressure is well-controlled with lisinopril, and I’ve been able to cut the dose since I’ve lost some weight these past 5 years, but it’s another drug that I take daily. It seems very likely that a low-carb diet will reduce my blood pressure, very possibly eliminating the need for this drug as well.
  3. High blood sugar. Back in 2003, I got a high blood glucose reading, and a stern talking-to about pre-diabetes. I responded by sharply reducing my consumption of soft drinks. That brought my blood glucose down to 91 in just six months. The past two years, though, my glucose has been ever-so-slightly high again. It’s not at a scary level, but I don’t like it even a little bit high. Undoubtedly, a low-carb diet will improve this.
  4. Weight loss. My weight is in the normal range, and has been since 2014. Further weight loss probably has no health benefit. Still, purely for aesthetic reasons, I’d be pleased to lose another few pounds. A low-carb diet will probably produce this result as well.

The main purpose of this post has simply been to get my thinking in order regarding what I’m hoping to accomplish. I have little doubt that a low-carb diet will produce the latter two improvements, but those issues could be dealt with easily enough through less drastic means. I have much less confidence about the former two, but improving those things would be a big deal for me—big enough to undertake the two-week test (at least), and maybe to change the way I eat going forward.
