A few years ago I made a shift in my thinking about fitness—a shift from trying to get enough exercise to trying to fill my days with movement. I haven’t changed my mind about that being the right way to go, but this year, especially since the pandemic started, has seen me step back into exercise mode.

I still think movement trumps exercise. But during a pandemic the advantages of exercise have aligned better with my needs and my circumstances. (I’ve written previously about how our fitness room was closed and how I switched to working out with gymnastics rings instead.)

I have to say that it has turned out pretty well for me this year.

One thing about exercise is that it gives you a bunch of metrics you can track, and on the metrics I’ve done pretty well. At the beginning of the year I could do 3 pushups and now I can do 4 sets of 12. At the beginning of the year I could do zero pull ups, and now I can do a set of 3 followed by 2 sets of 2.

Having the metrics is great for someone like me who’s a big ol’ nerd about tracking that sort of data, but it’s not just a matter of numbers. Those bigger numbers correspond to real-world capabilities. I’m definitely stronger than I was at the beginning of the year, in all kinds of ways. I’m also leaner. (I have more muscle, plus I let myself lose about 5 pounds in a so-far vain effort to be able to see the abs I’ve built.)

A lot of my fitness goals are related to attaining and maintaining specific capabilities. I want to be able to:

  • Pick something heavy up off the ground
  • Take something heavy off a high shelf and lower it safely
  • Clamber on top of a wall
  • Jump down from a wall
  • Jump over a ditch
  • Run away from danger (or toward someone in need of help)

That’s not a comprehensive list; merely a brief sketch of the sort of things I want to be able to do.

Even a quick glance makes it clear that many of them are skill-based activities. I’ve worked on some of them before (click through the parkour tag to see six or seven years worth of reports about my efforts in those directions), but I felt that my efforts were limited by a lack of strength. That probably wasn’t even really true—parkour is scalable—but to the extent that it was true, it’s much less true now.

The way to get better at a skill-based activity is to practice it. And most of that practice should not be practicing whole activities, but rather individual pieces of them.

There’s a word that means practicing all the individual bits that go together to make a larger move: training—something that’s been really hard to do during the pandemic.

The real reason I’ve switched to exercise is that during the pandemic, although I’ve been able to move, my opportunities to train have been limited.

I’m hoping to spend the summer training. I’m thinking parkour, but if I can’t get it together to do that, maybe I’ll go with rock climbing. (Indoor climbing would be a great winter activity, if the vaccines roll out fast enough that I feel like it’s already safe to engage in indoor activity before summer weather. But there’s no rule against indoor climbing during the summer either.)

It’s possible to do parkour training during the winter, as long as it isn’t too icy. I tend not to get out in the cold or wet to do so, but I’m working on overcoming that—with some success: I’ve been doing pretty well at getting out for runs, even during chilly/damp fall weather. But I’m at the point where I could really use some instruction in parkour, and that’s out-of-bounds during the pandemic.

In the meantime, I’ll go on doing my exercise, figuring it’s the best way to get myself ready for training, once circumstances align.

I’ve been working on dips for a while, but not with great consistency until just the past three or four months.

For a long time I was doing bench dips (where you put your hands behind you on a bench, stretch your legs out in front of you with your heels on the floor, and then push with your hands to raise your hips up to the level of the bench), to try to get my triceps strong enough to do real dips. In the fitness room there are some bars that can be put on the squat rack so you can do bar dips. I wasn’t really strong enough to do a good bar dip, but I’d sometimes do partials or negatives.

For parkour, you want to do wall dips, but I don’t know of any good chest-high walls in Savoy, so I haven’t practiced those in a long time.

Since I got my gymnastic rings around the end of March, I’ve been working pretty steadily on ring dips. (Which are much harder, because while pushing yourself up you also have to be able to stabilize your body.)

I’ve been following pretty much the usual progression—working on just a ring support (where you hold yourself in the top position for a dip), on negative dips (where you just lower yourself), and on partial dips (where you lower yourself only part of the way down, and then back up).

I’ve been gradually increasing the range of my partials, and a few days ago I thought I was doing a full, proper dip. I wasn’t really sure though—there aren’t any mirrors out under the sycamore tree where I hang my rings. So today I got Jackie to come and video me, so I could watch what I was doing:

I think those first two—especially the second—are legit dips. (The third, of course, is just a negative.)

I went to a parkour workshop yesterday held at 25 O’Clock Brewing in Urbana—one small bit of the UnConference (a very Urbana thing).

I’ve been interested in parkour for years now. I have included various bits in my own training, and also gone to train with the campus parkour group (the same people who led this workshop) a few times. For various reasons (social timidity, physical timidity, lack of fitness) I haven’t managed to establish a regular practice of training with the campus group. But it doesn’t mean that I’m not interested, so I was glad to learn about this workshop, which seemed like a safe, easy way to get back into it—and was.

We were led in a warmup, followed by some quadrupedal movement: Bear crawls, aka foot-hand crawls, both frontwards and backwards, followed by a move I know by the name “traveling ape,” although there are probably other names for it.

After the QM we went for a very short run to a wonderful object that could perhaps be described as a free-standing wall of old railroad ties locked in a wire cage. It had a flat metal top which together with the cage made it great for practicing cat hangs: The cage provides enough of a toe hold that even people with limited grip strength can hold on long enough to get a good workout.

The next thing we worked on was shoulder rolls. I was particularly glad for this part because I used to be able to do shoulder rolls, but at some point in the last 35 years lost the mix. Starting from a kneeling position, though, I was able to recover my roll. In just 15 minutes of practice I was back up to doing rolls from a squat. From there I’m sure I can work up to rolls from a standing position pretty quickly.

(Actually, the main delay is that for some reason the rolls made me queasy. I don’t remember that from 35 years ago, but yesterday I got queasy after a few minutes rolling, and my stomach didn’t completely settle down for several hours.)

After rolls we did some vaults. We started with the safety vault, which I’d already learned (and have continued to practice, because it’s really handy for things like getting across downed trees while out hiking). Then we proceeded to some initial progressions for the kong vault. I’d always thought of the kong as the most advanced vault, but that’s when it’s used to traverse a gap beyond the thing you’re vaulting. It can also be used like the safety vault as a way to get on top of some object, and that’s what we learned yesterday. With a low-enough wall (waist-high, rather than chest-high), I can already get on top with a kong vault.

Shout-out to restorative exercise specialist Ashley Price who spotted that the parkour workshop was going on and suggested that I attend.

Today I’ve already included a bit of parkour in the day’s activities, adding a bit of QM to my afternoon walk, both foot-hand crawling and a bit of ground kong. (The latter is excellent practice for reminding myself that I need to keep my knees together, something that does not come naturally.)

I’m pretty pleased with 2017 on a movement front. As I sat down to write this, I had been feeling a little discouraged about how slow my progress seemed on the strength front, but when I looked back at where I was one, two, and three years ago, I can see that I’m actually making steady progress. (And, after I’d started drafting this post, I managed to do a chin-up, so I’m especially pleased about that.)

I feel like I’ve pretty much managed to internalize my realization that movement trumps exercise. I certainly don’t move enough, but I’m much more inclined to notice now whenever I do something that minimizes or outsources my movement. This gives me a chance to say, “Never mind. I’ll go ahead and do that myself.”

Since I don’t move enough, I have to add exercise to the mix. Especially in the winter, when the cold and the dark and the ice make it tough to fit all the movement in, I exercise. And I pick my exercises with the goal of improving the capabilities—mobility (especially), strength, control and access to appropriate movement patterns—that I found were limiting factors last summer.

This last—access to movement patterns—is new. I’m just coming to realize that in many cases my limitations are not (or not entirely) a lack of strength or flexibility, but rather are due to poor patterning of the movement. More on that below.

Exercise

I stuck with the exercises I’ve been focusing on for three years now, and added a couple.

Squatting

I finally made real progress in squatting, and it turned out to be a really simple thing that made the difference—and probably a movement pattern thing.

In one of the classes I took with Ashley Price, she had us find the best squat we could do with perfect form. That is, we got in neutral posture with our feet hip width apart, our feet pointing straight forward, our femurs neutral, and then we squatted down only as far as we could go while keeping our shins vertical.

My discovery was that by first getting as far down as I could with my shins vertical, I was in a posture that let me easily lower down the rest of the way into a deep squat. It’s not a perfect deep squat (I wouldn’t want to load up my back with a heavy weight and lift it) and it’s not quite to where I can comfortably rest at the bottom of a deep squat (although it is getting pretty close), but it is now a useful capability. For example, on the last day of the year I got down in a deep squat to look over the choices in our liquor cabinet, and ended up lingering there for some little time. (The range of choices is rather large just now, thanks to a generous gift and a bit of splurging on our own.)

Basically, I’m happy with my progress on squatting.

Hanging

Here I’m finally making great progress—chin-up!

Other than that I’m pretty much doing what I’ve been doing—negative pull-ups. Sometimes I do them for volume (I’ve done as much as 3 sets of 7, or 2 sets of 8 plus a few). Other times I’ve been doing many fewer sets and reps, concentrating instead on doing them very slowly.

Just since doing my chin-up I’ve begun to recognize a movement pattern issue here as well. Based on how sore my traps were after my first chin-up, while my lats weren’t sore at all, I think I’m failing to initiate the pull with my lats. I’m addressing that two ways. First, I’m doing the negative pull-ups very slowly, trying to find the point where I transition to using my lats and emphasize that part of the move. Second, I’m trying to specifically engage the lats by pulling my shoulders back and down before trying to pull myself up.

Besides all that I’m sticking with my other hanging exercises—swinging side-to-side and back-to-front, leg raises, knee-ups, and I’ve added some twisting knee-ups as well, turning my hips to alternate sides and raising my knees toward my elbow on that side. I’m also ready to start doing some traversals along the bar.

Wall dip

I haven’t made much progress here, for much the same reasons as last year: wall dips are hard, and I’ve been working on various progressions instead. I play around with bench dips and (rather shallow) parallel bar dips and wall supports.

Another reason I’m not making much progress here is that for my main pushing exercise I’ve been emphasizing pushups.

Toe stretches

I’m reasonably pleased with my progress on toe flexibility as well, even though I haven’t actually increased my range of motion much. What I’ve done is improve my ankle dorsiflexion enough that I’ve been able to start doing the things I couldn’t do because of limited toe flexibility.

There’s a particular move I wanted to be able to do, that involved shifting from a squat to a deep knee bend, then lowering the knees to the ground and then kneeling. It can also be reversed by flexing the ankles to tuck the toes under, rocking back to get into a deep knee bend, and then shifting to a squat for standing back up.

Among other things, this is a martial arts move: You can move from kneeling to standing while keeping your hands free to block an attack (or prepare to launch one).

I can sorta do that now. Not smoothly, and not without an amount of toe stretching that feels a bit excessive, but vastly better than two years ago where a single attempt hurt my knees and toes enough that it took weeks to recover.

Pushups

As I said, instead of dips I’ve instead been focusing on pushups. I’ve made good progress here as well: I can now do 8 pushups (up from 1 a little over a year ago). I’ve also greatly improved my form—keeping my elbows tucked in close to my sides, rather than letting them flair out as I’d probably done since I was a kid in gym class. (Your humeri should be neutral with your elbow pits pointed forward.)

Now that I can do 8 pushups it’s about time to start doing multiple sets—maybe starting with 2 sets of 5? I’ll try that in a couple of days.

I don’t have long-term plans to emphasize pushups though. I’ll keep doing them, but once I can do a couple of sets of pushups and still have some strength left in my triceps, I’ll get back to work on the various sorts of dips.

Kettlebell swings

This year I added kettlebell swings to my exercise regimen. I want to talk about this a bit, because there’s a story here.

About a year and a half ago I was out on a very long walk with Jackie. Toward the end we sat down on some concrete benches for a short rest, and I found that there was an uncomfortable lump right behind where I was sitting. Shifting around to find a lumpless spot was not successful. Eventually I figured it out: I had lost enough weight that I no longer had enough cushioning to keep my tailbone up off the bench; the lump I felt was my coccyx.

Figuring that bigger glutes would be a better choice for keeping my coccyx up off the bench than fat anyway, I started boosting the weight I used in my goblet squats. Then I remembered an old post by Tim Ferris that recommended kettlebell swings as the best glute exercise. Then some anonymous kind soul donated a 45 lb kettlebell to the Winfield Village fitness room.

Looking at my training log, it appears that I started doing kettlebell swings in January, and worked up to 3 sets of 25 by April. As Tim had recommended 75 reps as a target, I’ve left it there. I don’t have data on the size of my glutes, but I’m no longer bothered when I sit on a hard bench.

I use the kettlebell swings as my high-intensity interval training as well. A set of 25 swings spikes my heart rate up right toward my max heart rate. (I’ve actually seen heart rates above my estimated max heart rate, which just means that the estimate is a bit off.) Each set takes about 50 seconds, and I follow it with as much rest as I need to get my heart rate back down around 100, which works out to two or three minutes.

I’ve toyed with the idea of adding a fourth set, and might yet do that.

Non-exercise movement

My main non-exercise movement is and always has been walking. It was a bit limited in the second half of this year because I hurt my feet, and one foot in particular has taken a long time to recover.

I think what happened was this: I was waiting for the bus, which unbeknownst to me had been rerouted due to road construction. Seeing the bus zip past a block away, I took off running to try to catch it at the next stop. In the rush I think I must have fallen into an old heel-strike movement pattern, bruising my heels, resulting in this nagging foot pain. Only in the last few days of the year does it seem to finally be completely resolved.

Walking

I still walk a good bit for transportation, just less than I was doing before I hurt my feet. I’ve also done less walking with Jackie since she started working at Great Harvest bakery. (This does not mean less walking for her—she walks to work most days.)

I expect my walking quantity to return to its old baseline quantities in the new year.

Running

Running was also curtailed by my foot injury. Before I hurt my foot I had been increasing my running distances as well, working my way up to where I did an 8-mile run for the first time in many years.

Some of my running is exercise, but a good bit is movement (as, for example, the sprint to catch the bus where I injured my feet.)

Parkour

I did spend a little time with the campus parkour club, but once again timidity (both movement timidity and social timidity) kept me from doing as much as I might have.

Each summer I mean to step this up. Maybe 2018 will be the year.

Taiji

For most of the year I teach two taiji classes—a beginners class that meets for an hour twice a week, and a group practice for continuing students (we don’t consider ourselves “advanced”) that meets for an hour three times a week. Besides that I do some taiji and qigong throughout most days. I do some qigong to loosen up in the morning. I do some before lifting to warm up, and then I do some between sets as “active recovery.” I might do a whole short form when I feel like a little moving mediation would do me some good, or even a whole long form when I feel like a lot of moving meditation would do me some good.

Basically, I do a lot of taiji.

Even when I’m not teaching I include it as part of my daily movement, simply because it has proven itself such a powerful tool for helping me move and feel better.

Push hands

Over the summer I got back together with my friends who practice push hands a few times, but we were never able to get a regular thing going, which is very sad. I’ll try again next summer.

Stewardship work days

I have continued my practice of joining Jackie for occasional stewardship work days at natural areas in and around Urbana. (I even did one without Jackie—a prairie burn.)

These are perfect examples of non-exercise movement: We don’t do them for the exercise (although we get plenty); we do them to improve the land.

They are very satisfying for many reasons—doing hard work with friends is always satisfying, contributing to the community (making the parks better) doubly so. I think an additional reason is that the actual physical movements and mental activity that we do while locating and removing invasive plants is virtually identical to those that our hunting-and-gathering ancestors must have done for most of the past two hundred  thousand years. (I see now that I made exactly the same point last year.)

Looking ahead

With one possible exception, my plans for the new year don’t include big changes, just continuing progress. (The possible exception is treating myself to a month pass to Urbana Boulders and putting my new upper-body strength to work climbing walls.)

I have had some success in getting my mind right with the cold, this year in particular, but also gradually over the past several years. I’m getting in more outdoor exercise this year than last, and a lot more than I did five or ten years ago. That, plus the indoor strength training and the taiji, look to stand me in good stead for getting 2018 off to a good start.

We’re planning a spring trip to some national parks in southern Utah which will entail a good bit of walking, so we have that bit of extra motivation to keep up with our walking over the winter.

Happy New Year!

This year didn’t have a stunt like last year’s Kal-Haven Trail walk. Instead I tried to spend the year turning my realization that “getting plenty of exercise” is a poor substitute for “moving all day” into something that guided my behavior all the time.

I did not have perfect success. I still spend too many hours sitting at my computer during the day, and then spend too many hours sitting and watching videos in the evening. Neither did I fail. I included movement throughout the day most days of the year, especially through the spring, summer, and fall.

Although movement was my focus I certainly did not give up on exercise. In particular, I used exercise to make progress on developing certain capabilities that I lack.

Exercise

I had four specific things I was going to work on for 2016: squatting, toe flexibility, hanging, and wall dips. I made good progress on all them except the toe flexibility.

Squatting

My limitations in squatting turn out to be almost entirely mobility. (My personal test for this is the goblet squat. Using a modest weight—just enough to serve as a counterbalance so I can get down into a deep squat—I can do a dozen reps.)

The other ways (besides a counterbalance) to compensate for squat-limiting mobility issues are heel bolstering, hanging onto something in front of you, and taking a wide-legged sumo stance. I don’t practice the last, but use it when I want to look in my mailbox (which is down low) or into a low cabinet or the bottom of the refrigerator. I don’t much practice hanging onto something while squatting either. Most of my practice has focused on bolstering.

With a modest amount of heel-bolstering I can now get down into a deep squat, and linger there comfortably. Almost every day I do my calf and hamstring stretches and then do some squatting with progressively lower heel bolstering. I haven’t done as much hip flexor stretching as I probably need to. I’ll add that to my daily routine, both for the stretching itself, and also for the motor control practice—I’m kind of wobbly doing a hip flexor stretch, which probably causes all the related muscles to tighten up some.

Hanging

My hanging is probably where I’ve made the most progress. I can now hang for long enough (90 seconds) that there’s time to do stuff while hanging—things like swinging back-and-forth or side-to-side, pulling my knees up toward my chest, or raising my legs up in front of me.

To just hanging I added negative pull ups. After an ill-advised increase in volume hurt my shoulder in July I eased up just a bit, but still made good progress, working up to 3×5 negative pull ups.

When that turned out not to have enabled even one pull up, I changed the exercise just a bit: Now I’m doing the negative pull ups even slower, trying at each point to see if I can (from that point) lift myself up, or at least stop my descent.

Soon. Soon I will be able to do a pull up.

Wall dip

I thought I was ready to do wall dips a year ago, because I could do wall supports—support myself with my hands on the top of a wall. I could even sort-of do one wall dip—lowering myself and then pushing back up.

I didn’t train that exercise enough in the summer, largely because I didn’t have a good wall to practice on. When I came back to it in the fall, I found that going from one wall dip to two wall dips was quite challenging.

Something that is well-known in the bodyweight exercise community—that I know, but always seem to have trouble applying to myself—is that when an exercise is too hard you should back off to an easier progression.

So, just now that it’s winter, I have finally backed off a bit to an easier dip progression: bench dips (where you have your hands on a bench behind you, with your legs stretched out in front of you, and you lower and raise yourself with your arms while some weight rests on your heels).

I’ve already worked up from 1×8 bench dips to 1×12. Pretty soon I’ll be doing 3×12. Then it’ll probably be time to return to wall dips. I’ll also keep up with my wall supports, when I happen upon a good wall.

Toe stretches

The area where I’ve made the least progress is toe dorsiflexion. That’s been kind of frustrating.

This may be one area where what I need is not just more stretching (which hasn’t seemed to do any good at all) but some sort of deeper tissue work to break up adhesions, recover space in the joint capsule, etc.

It just now, while writing this, occurred to me that I probably I need to expand my focus to include my whole foot and not just the toes. So that can be my winter practice: the same, plus extra foot mobility.

Pushups

I’m adding a fifth area of focus for 2017: Pushups.

They had not been a priority before, because pushing strength in that plane is not particularly important for parkour. And yet, it’s such a basic exercise, it seems silly not to give it a little attention—particularly because I was actually really weak in that area: I could barely do one pushup.

I just decided to add pushups a few weeks ago, about the same time I figured out I should back off from wall dips to bench dips. So when I found I could barely do a pushup, I quickly realized that I should back off to something easier for that move as well. So I’ve just started doing bench pushups (hands on a bench, rather than on the floor). I can do 1×8 of those as well.

Because trying to do a pushup is so easy, I probably won’t wait until I can do 3×12 bench pushups before switching back to regular pushups; I’ll just include an occasional few (as many as I can do) in the mix. Once I can do 5 or 6, I’ll switch back to actual pushups.

Non-Exercise Movement

Walking

Without a stunt walk to work up to, Jackie and I did not walk as much this year as last, but we did plenty of long walks and at least one very long walk. Some of our walking is exercise, but most of it is either just a way to get places, or else companionable social time together—often both.

Running

I also did a good bit of running, especially before August. As I’ve been doing more and more these past two or three years, I skipped most of the short and medium runs, letting walks stand in for those, and just did the long runs. That worked surprisingly well, and in July I did a 7.25 mile run, my longest run in years. This is probably a slider as to whether it counts as “exercise” or not, but I do it as much because I enjoy it as I do it for fitness, so I think it legitimately goes here.

Parkour

Early in the summer I did some training with the campus parkour group, which was great fun. I found it a bit stressful: I’m not strong enough to do some of the basic moves, and I’m too timid to commit to some of the ones I could do if I’d just go for it. I quit going in July when I hurt my shoulder, and then never got started again. I will go back. Maybe being stronger will help some with the timidity as well.

Taiji

I’ve continued to teach taiji, and to do taiji for myself when I’m not teaching it. The qigong practice that we start each session with provides a pretty good mobility routine (although lacking in the things I mention above: hip flexion, ankle dorsiflexion, and toe dorsiflexion). It builds strength (especially leg strength), balance, and precision (matching movement to intention). It includes a meditation practice—in each class we sit for a few minutes and stand for a few minutes, as well as trying to approach the form itself as moving meditation. It fills so many rolls it goes way beyond exercise (although it’s that too).

Push hands

One new thing I added—perhaps the most fun of all—is push hands. Closely related to taiji and qigong, it’s kind of a transitional step between taiji as a moving meditation and taiji as a martial art. It deserves a post of its own, so I won’t try to describe it here, and instead just thank the new friends I’ve been able to push with and say how much I’m looking forward to practicing again now that the holidays are over.

Volunteer stewardship work days

This doesn’t really describe a category of movement at all, which is I guess the way in which this is totally not an exercise.

Jackie’s master naturalist program includes a substantial volunteer commitment. It can be met a lot of different ways, but one is working in the various parks, doing things like clearing invasive plants, planting native species, and so on.

I’ve just done a few of these, but spent a couple of hours each time moving. Some of the movement—in particular, gathering prairie seeds—must have been identical to what our ancestors would have done in gathering seeds. Others were perhaps slightly different—we had saws and pruning clippers that our earliest ancestors would not have had—but once something has been cut, the lifting and dragging is right back to being the exact same movements that humans have been doing for hundreds of thousands of years.

I’m always torn this time of year, between looking forward to spring and being able to move outdoors again, versus motivating myself to get outdoors anyway (also: finding ways to move more indoors). I’m trying to discipline myself not to just defer my plans to the spring even implicitly such as by saying “I’m looking forward to spring and being able to move outdoors again.”

I’m pleased with 2016, a year of great progress in my movement practice, and I have every reason to hope that 2017 will be even better.

Even though I’m finding my self-care regimen for seasonal depression pretty adequate these days, I’m always interested in more tools. One thing that caught my attention recently was an interview with Brant Cortright in which he talked about his book The Neurogenesis Diet and Lifestyle.

Cortright has a bunch of interesting things to say, one of which I already knew: that depression is not a disorder of serotonin deficiency. According to him—and this I did not know—the way SSRIs work is by promoting neurogenesis. In the interview he said that depression turns out to be caused by a lack of neurogenesis, as are several other disorders (e.g. Alzheimer’s).

I checked the local libraries for copies of his book without success, but in my searches I happened upon this article: Successful brain aging: plasticity, environmental enrichment, and lifestyle by Francisco Mora, which seems to cover pretty much the same ground.

People are looking very hard at drugs besides SSRIs to promote brain plasticity, but the whole idea sounds problematic to me, so I’m interested in the various non-drug interventions suggested by Cortright and Mora. Fortunately, it seems that neurogenesis is easy to increase, by doing the obvious things we already know about:

  • Environmental enrichment
  • Calorie restriction
  • Aerobic exercise
  • Adequate levels of certain nutrients (omega-3s, vitamin E).

I think of my artist dates in particular as environmental enrichment, but of course time spent in nature counts as well. The parkour I do probably counts double, because there’s learning how to execute the moves, but there’s also learning to see the environment as a place where those moves are useful.

My weight loss practices have been substantially motivated by the science around calorie restriction as a way to improve health generally, with additional neurogenesis just one factor.

My experience over the previous 30 years convinced me that approaching calorie restriction in a numerical, analytical fashion—tracking what I ate, estimating the calorie content, aiming for some target X% below maintenance—would be unsuccessful. Instead, I came at it from the other direction: If I’m losing weight, I must be restricting my calories.

The caloric deficit implied by my weight loss over the past five years is just about 100 calories per day. Maintenance for me is probably around 1800 calories per day, so I’ve averaged about 5.5% below. It would probably be more accurate to say that I’ve averaged about 10% below maintenance for about half that time, as I’ve generally lost weight during the summers while maintaining a stable weight through the winters. Either number is well shy of the “20% to 40%” reduction that’s been shown to decrease the rate of aging of the brain, but I rather suspect that the benefit exists even at these lower levels—with the added bonus of being sustainable over a much longer period of time. (I mean, how long can you maintain a 40% deficit below maintenance before you simply waste away?)

According to Mora, aerobic exercise seems to increase neurogenesis by the same chemical pathways as calorie restriction. According to Cortright, it has to be aerobic activity of substantial duration—some twenty minutes or more. In particular, the sort of HIIT workouts so beloved of the paleo/primal folks don’t seem to produce the same effect. That’s fine with me: Humans are much too well-adapted for endurance running for me to buy into the idea that primitive humans didn’t do marathon-distance runs when they needed to. Besides, I enjoy long runs.

Of course, neurogenesis is reduced by the obvious things:

  • Neurotoxins (mercury, lead, pesticides, etc.)
  • Traumatic brain injuries (concussions, etc.)
  • High blood glucose levels
  • Stress.

My parents made a considerable effort to keep me and my brother free of neurotoxins, and I have managed to avoid concussions so far. I’m sure I subjected myself to excessive blood glucose levels for years, but I think I’ve got that under control now. I also subjected myself to excessive levels of stress for years, due to the vicious circle of my seasonal depression making me unproductive, my lack of productivity making me stress about losing my job, and the stress no doubt worsening my depression. I’ve got that under control now as well.

Really then, this whole neurogenesis thing doesn’t so much give me new strategies for staving off depression, as provide a conceptual framework for organizing the strategies I’m already using.

Even just that seems worthwhile.

I do a lot of things to stave off winter depression. I walk. I spend time in nature. I spend time walking in nature. I move in other ways—taiji, lifting, stretching, running, parkour. I use my HappyLight™. I take vitamin D. But probably most important is finding things to take delight in.

Jackie doesn’t suffer with the dark days of winter the way I do, which is probably a matter of brain chemistry, but perhaps another factor is that she is very good at taking delight in winter as an opportunity to wear her woollies.

I’m trying to do the same.

It helps that I have new winter clothes, and old winter clothes that fit again. The photo on this page shows me walking in nature, wearing a purple sweater my mom knit for me years ago.

Besides my old sweaters and my new sweaters, I have a smashing wool vest that Jackie gave me, some wool pants that I bought as field pants (but that are perhaps too nice to wear in the field), and a vast collection of scarves that Jackie wove and knit for me. And that’s just the woollies. I also have a nice collection of moleskin and flannel garments perfect for winter, various fleecy things, and a range of jackets and coats to cover all possible temperatures from “slightly brisk” to “well north of the arctic circle.”

This year, I’ll try to take delight in my seasonally appropriate garments, especially the woollies, and see if that won’t carry me through to spring.
