The study reported in Exercise for Weight Loss (NYT) implicitly recommends an amount of exercise that is almost precisely I was doing in 2012 when I found a fitness regimen that worked for me.
“In the study, that meant working out six days a week for up to an hour, or around 300 minutes a week.”

Only very old playgrounds still have monkey bars, jungle gyms, or pull-up bars. This modern playground at least has a horizontal bar at the top of the slides which is suitable for doing inverted rows. I took the opportunity of running past to do a quick set. 🏃🏻♂️
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:
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.
It used to be that I was pretty casual about warming up before exercise. If the weather was nice, I’d go for a 20-minute walk. If the weather was crappy, I’d spend 5 minutes on the treadmill or an exercise bike. I’d do just enough to get my heart rate a little bit elevated, and raise my body temperature a degree or two.
That worked okay for years, but at some point I started having injury problems. I’d hurt my feet when I ran. I’d hurt my wrists when I tried to do pushups. I’d hurt my shoulders when I tried to do pull-ups. Each new injury taught me to warm up that body part a little more carefully.
As I’ve gotten older, I’ve found that it is very much worth the time and effort to do a long, slow warm-up.
I wrote a little while ago about taking some time to check-in with my body and with my exercise venue, but I didn’t talk much about specific warm-up activities. This post is an attempt to capture my current somewhat maximalist warm-up, primarily as a checklist to use myself. (Without one I tend to forget activities, and then only remember them later, when some body part twinges. “Oh, yeah, I forgot to do the shank rotations!”)
Just as a note: If I don’t mention some other rep count, I do most of these for 12 reps. If it’s a bilateral motion, I often do just 6–8 on each side.
I used to start with the neck and work my way down, but I’ve switched to do my feet and ankles up front (because it’s there that I’ve had the most persistent injuries), and then go back to the neck. Here’s what I do:
I don’t do any of those as strengthening exercises, I do them as range-of-motion exercises. At the end of the warm-up (or the end of the workout) I sometimes come back to the calf raises and do a few sets of one-footed calf raises, which can be intense enough to be a calf-strengthening exercise.
The thing I do not do for my neck is head circles. I tell my taiji students that you should never let your head loll around at the end of your neck. (Exception: If you are the heroine in a romance novel and have fainted into the arms of the bare-chested hero. Then your head can loll around at the end of your neck.)
What I do instead is this, an exercise I call “motivated looking”:
I don’t do any of these as a stretch; I keep within my comfortable range of motion at all times. I also don’t close my eyes; the point here is to actually look in those directions, as if to see what’s there. That’s why I call it motivated looking.
I just do about 4 of these in each direction.
Since the pandemic started I’ve been largely focusing on upper-body strength, mostly exercises with gymnastic rings, which hit the shoulders pretty hard. I have found that spending several minutes just warming up my shoulders helps a lot.
I like to go straight from elbow drills to rhomboid pushups to squat prep #1, because they all start from about the same position.
I usually do my wrist exercises in the middle of my shoulder exercises, typically right after my shoulder circles, but there’s a bunch of them, so I wanted to pull them out into their own section.
Let me take just a moment to acknowledge that this is insane. On days that I do a full workout (which was running 4–5 days a week over the summer), I do very nearly this entire set of warm-up exercises. (Up to now I’ve often forgotten several, since until now I haven’t had a list to follow.)
This can easily take me 40 minutes, which is a pretty large chunk of the day to dedicate just to warming up.
Even then I’m not done—I go ahead and do “straight-elbow” versions of push-ups, pull-ups, or inverted rows (to match the full version of any of those exercises that are in my plan for the workout).
I also do a subset of this warm-up even on days that I’m not going to exercise.
The reason I do all this is simply that I feel better when I do. It’s not just my workouts that go better when I’ve gotten in a proper warm-up. Everyday activities go better as well—bending over to pick something up off the floor, standing up from having sat down on the floor, getting something down off a high shelf, etc. Everything I do for the rest of the day is easier and more comfortable, once I’ve gotten properly warmed up.
So, there you go. Feel free to take any or all of these activities to include in your own warm-up routines. If there’s one that isn’t clear, let me know—I could tweak the text, take a photo or even make a video, if that would make it clearer.

For some time now I’ve been aiming to do my endurance training at my MAF heart rate. MAF stands for Maximum Aerobic Function, and it’s the heart rate where you’re producing the maximum output without having to use anaerobic systems. Although the MAF formula just produces an estimate, there’s quite a bit of data to back it up.
If you do almost all your training at MAF, you’ll get better (run faster) at that heart rate. The idea is that you first do that, and only when your performance plateaus do you need to start doing any sort of speed work (and then not much of it).
As I say, for some time I’ve been aiming to train at my MAF heart rate, but it’s a low enough level of intensity that I’ve persistently had trouble not running too fast. I have a heart rate monitor, but it’s not very useful during a run, because my heart rate is displayed on my phone, and I don’t want to run around carrying my phone where I can see the screen. The upshot has been that I’ve inadvertently done a great deal of my training somewhat above my MAF heart rate, which rather defeats the purpose.
To get a better grip on my MAF training, I finally broke down and bought another heart rate monitor, which displays my heart rate on my wrist so I can check it while I’m running. It also has an alert function, so I can set it to vibrate if my heart rate goes above some value. After looking around a bit, I settled on the Mi Band 4 (which is available for cheap because the Mi Band 5 is now out). It does the thing I want well enough. (It also does a bunch of other stuff that I don’t care about, and some things that I do care about (sleep tracking), but that I do some other way, such as with my Oura ring.)
After a shakedown run a few days ago, where I spent a lot of time trying to figure out how to use the device the way I wanted, today I went out for a run where I tried to use it for some proper MAF training, and I think I was very successful. I probably only spent two or three minutes (out of a 51-minute run) with my heart rate above my target.
This very easy run was nice and gentle. Sitting here at my computer maybe an hour after I got home, my heart rate is already back down to just 64 bpm, which amounts to a surprisingly complete recover. After a run only a little bit faster, I’d expect to see my heart rate stuck in the 70s for several hours.
Now to see if regular training this way produces the speed gains it is reputed to.

Objectively speaking, autumn is probably the best season. Not cold like winter, stormy like spring, or hot like summer, autumn has great weather—totally aside from the pretty colors and Halloween (arguably the best holiday, albeit in a near tie with Groundhog’s Day).
For pretty much my entire adult life I’ve dreaded the cold dark days of winter, and among the many ways that Seasonal Affect Disorder affected my life in a negative way was that it ruined autumn. I could usually get past the summer solstice okay (although in the back of my head, I knew that the best day of the year had come and gone), and I could keep it together through July and August. But by the beginning of September I knew that winter was coming, and I’d spend the last months of nice weather steeling myself against the dark days to come.
It was the dark that bothered me, more than the cold. It’s easy to armor yourself against the cold—flannel, moleskin, fleece, wool, down—there are many ways to deal with cold. But even a Verilux light therapy lamp (which does help) does not solve the problem of the dark days of winter.
All of which is merely an introduction to saying: Last winter I did not suffer from SAD!
I had meant to write something at the time, but I didn’t want to speak too soon, and then once it was spring, it didn’t seem like the most important thing.
I don’t want to jinx anything, and I’m sure the right combination of stressors on top of the cold and dark could once again put me in a bad place, but something more important has changed than just a good year: I’m no longer afraid of the dark days. Maybe I’ll suffer from SAD again, and maybe I won’t, but at least the mere knowledge that the cold and dark is coming is not ruining my fall! In the back of my head I seem to have turned a corner and developed some confidence that I’ll be okay despite the season.
So what has helped?
First, not having to work a regular job. I’m sorry that I can’t recommend something more generally available, but that was the biggest thing that made a difference. Because I don’t have to be productive on a day-to-day basis, I avoid the depression-spiral that used to result from realizing that I wasn’t getting anything done, which made me anxious about losing my job and being unable to support my family, having the anxiety make me more depressed, and the depression making me even less productive. That used to be a killer. On top of that, because I don’t have to be in the office during any particular hours, I’m able to spend a few of the few non-dark hours of the day outdoors, taking advantage of what daylight there is (and making some outdoorphins).
Second, exercise. I always knew it was important, but I took things up a notch each of the last few years, and each new tick up turned out to provide an enormous improvement in my mood. In my experience, all kinds of exercise are good. Endurance exercise is good. High-intensity interval training (HIIT) is good. Skill-based training—ballet, parkour, animal moves, taiji—is good. Resistance exercise (lifting) is perhaps best of all. Letting the dark days of winter compress you down into a lump that seeks (but never finds) cozy because you’re unable to move? That’s the worst.
Third, community. Granted this is not so easy during a pandemic, but even people that you only see on-line are still people you can have a connection with, and having connections is good.
Fourth, something to look forward to. It can be almost anything. Last year I was looking forward to having my family visit. Other years I’ve looked forward to taking a vacation somewhere warm. Even little things help me—ordering some fountain pen ink or cold-weather workout clothes and then looking forward to the package being delivered, and then looking forward to using the newly acquired item.
Fifth, a project that you can make progress on. Ideally something without a deadline—at least, no deadline during the dark days of winter—but a project that you care about. Something that you can spend a few minutes on every day and see some headway that brings you closer to completing it. Creative projects are good, but creativity isn’t as important as just having a thing that you’re working on, and making steady headway.
Not suffering from SAD, even if just for one year, has been wonderful. Having some confidence that things will be okay-enough this winter that I’m not spending all fall dreading it is even more wonderful-er.

Went out a little fast at the start, partially because it’s chilly and I was cold, but mostly because it felt so good to run a little fast. 🏃🏻♂️ Photo from about the mid-point, where I managed to ease it back down a little.

Jackie attended the annual Illinois Master Naturalist’s conference last week, and came away with any number of interesting tidbits, but one in particular stuck with me: Forest bathing is like ergonomics.
Both Jackie and I have had our understanding of ergonomics informed by Katy Bowman, who points out:
Modern ergonomics is not the scientific pursuit of what is best for the human body, but the scientific pursuit of how the human body can be positioned (in one position, for eight or more hours at a time) for the purpose of returning to work the next day, and then the next and the next and the next.
Don’t Just Sit There by Katy Bowman; excerpt.
What Jackie learned at her conference was that the Japanese concept of forest bathing (shinrin-yoku) has roots in the same idea. When Japanese salarymen started dying from overwork, a lack of exposure to nature was put forward as a partial explanation.
If the problem is a lack of exposure to nature, then immersing yourself in nature is an obvious solution. But, of course, actually immersing yourself in nature would take too much time out of the workday. Hence the research into forest bathing is all about finding the minimum effective dose. There is little or no research into figuring out the optimum time for humans to spend in nature.
Keep that in mind when you read yet another article about how just looking at a forest scene for 20 minutes reduces salivary cortisol 13.4%, or walking in the woods for just 40 minutes improves mood and boosts feelings of health and robustness.
I’m not so much interested in the answer to the question, “What’s the least number of minutes I can spend in nature and not die early from overwork?”
I’m more interested in questions like:
I have my own tentative answers to many of these questions, but very little data.
