Today’s walk: 12.35 miles, plus taiji

Jackie wanted to walk to the Savoy Recreation Center where we take our taiji class, and it was about time for another long walk, so we did.

Our training plan for getting in shape to walk the Kal-Haven trail calls for, I think, a 5-hour walk this week. We didn’t walk quite that far, but if you count the hour we spent doing taiji as part of our workout (which I think is fair, since we’re on our feet for the hour), I think we just about hit the mark.

I was a bit peeved with Endomondo, which seemed to have crashed the Samsung tablet I use to gather the data on our workouts, but I quickly got over it, because it doesn’t seem to have lost the data on our workout. The walk to Savoy Rec and then to Bo Peep’s where we had lunch is shown here:

The tablet rebooted while I was getting it out of my pack at lunch, but once it was up and running again I restarted endomondo and then started a fresh workout to track the walk home. That workout is here:

I paused the app during taiji, and then it turned itself off during the lunch break, so you’d have to add about two hours to the total time of 4:17 (2:40 plus 1:37) to get a comparable time to previous workouts (where I just left the ap running the whole time).

We left home around 7:10 AM just slightly later than planned, and walked the first leg quite briskly, covering each of the 5+ miles to Savoy Rec in under 20 minutes (and the first mile in just 18:04). After lunch we went a little slower, but still kept to a roughly 20-minute pace.

I think we remain nicely on-track for being in shape to hike the Kal-Haven trail sometime in July.

Fictional characters getting in shape

I’m a huge fan of a particular sort of scenes in stories—the scenes where the hero gets into shape.

I was reminded of this recently, after reading Greg Rucka’s Critical Space, a thriller I read after it was mentioned by Marissa in a recent post, which has an excellent instance of this sort of scene. The getting-in-shape sequence in this book takes the form of a montage (much as you might see in a movie with such a sequence) written in second person. You swim. You run. You do yoga and ballet. You take supplements and you eat lots of fruit. You lift weights. You see the changes in your body. You learn to be an assassin.

I have long been a fan of these scenes, both in books and movies. They’re a key part of the original Rocky movie, of course, and are practically all there is in Rocky III. I’m especially fond of the getting-in-shape sequence in the book Man on Fire by A. J. Quinnell, and I’m still bitter that the movie completely omitted the sequence. (Easily the best part of the book.)

A lot of sf and fantasy stories have versions of these. For example, Steve Miller and Sharon Lee’s Liad books often have characters learning a martial art. In these, as in a lot of fantasy stories, the hero or heroine often turns out to have an especially high level of natural talent for the art. I view this as a negative—it’s more interesting to me when the hero lacks any extraordinary skill, but manages to excel through hard work. Patrick Rothfuss’s Wise Man’s Fear does a particularly good job in the scenes where the hero learns a taiji-like martial art. Instead of the hero having preternatural talents in the area, his success comes from seizing an opportunity (and, of course, having preternatural talents in other areas).

A whole genre of its own is the boot camp story, where the heroes not only become fit and learn a lethal skill, but also learn something about teamwork and camaraderie.

Anybody out there like these sequences as much as I do? Can anybody point to books or movies with particularly good instances?

Tai Chi class I’m teaching

Tai Chi flyerI’m going to be teaching a Tai Chi class this summer for the Champaign Park District. Classes will be 8:30–9:30 AM Mondays, Wednesdays, and Fridays. There’ll be a first session running from June 3rd to July 26th and then a second session from August 5th through September 27th. (This update to my post of a week or two ago is because the Park District has produced some fliers with class info: Tai Chi fliers.)

We’ll learn some moving Qigong exercises, an 8-movement form, and provide an introduction to meditation.

The class is appropriate for beginners, although other students are also welcome.

Register at the park district website or at any park district office.

Update 3 June 2013: The class has started, but the Park District is keeping registration open for another week or two, hoping to pick up another student or two.

Teaching Tai Chi this summer

I’m going to teach a Tai Chi class for the Champaign Park District this summer.

Screen grab of the Tai Chi course description.
Screen grab of the Tai Chi course description.

The park district doesn’t put their course descriptions on the web except in the form of the pdf file of the course catalog, which wouldn’t be so bad, except that they also don’t put the pdf file on their website, but instead offers it through Scribd—which makes it excruciatingly difficult to download the file. Otherwise, I’d go ahead and link to something. But, as I can’t find anything useful to link to, I’ll just paste in this screen grab from their on-line catalog.

I’d encourage any local folks who are interested in an introduction to Tai Chi to sign up. It costs $50 for park district residents and $75 for non-residents. The first session runs from June 3rd through September 26th. The second session runs from August 5th through September 27th.

Longest run in years

We had a few days of mild weather this past week, giving me a chance to get some outdoor exercise. I took advantage by running almost 6 miles on Monday. That’s my longest run in years.

Back in 2004, I ran 8 miles as my last long run before running the 7.1-mile Lake Mingo trail race. But since 2008, which is as far back as my current exercise log goes, this run (5.83 miles in 1:11:35) is my longest.

I started at the Savoy Rec Center after taiji class, and ran all the way home. Here’s the route:

It was probably a bit further than I should have run. It left my knees kind of sore the next day. I’d gone 4.6 miles on Saturday—a much more reasonable distance for my current abilities, and probably part of the reason Monday’s 5.83 was too much. But knowing that I might well not get another chance to run outdoors for months, I couldn’t resist the urge to overdo it.

I never had any particular interest in extreme endurance runs. (I had no ambition to run a marathon, for example.) I ran for two reasons:

  1. Efficiency—I wanted to get enough exercise to develop and maintain a basic level of fitness with the least amount of time, effort, and money devoted to the effort.
  2. Capability—I wanted to develop and maintain the ability to be able to run if it was necessary.

Both those goals are easily satisfied with a weekly mileage of 10 to 12 miles—a long run of 5 or 6 miles together with two or three runs in the 2 to 3 mile range—which is where I’m at right now.

There’s certainly no reason to run further for health. If I wanted to devote extra time and effort to improving my health there are a hundred better things to do (starting with eating better, but including things like improving flexibility and core strength). Running more is probably a negative for health—my chance of injury just goes up from here. The only thing running further would improve is my ability to run further.

Even knowing all that, I find that I always want to run a little further. Once I’ve run five miles, I want to run six. Once I’ve run six, I want to run seven. I hesitate to follow that progression to its logical conclusion. And yet . . . .

Losing weight

I’ve lost a good bit of weight over the past 18 months. I haven’t talked about it much here. It’s bad enough when this starts seeming like an exercise blog; it will not become a weight-loss blog.

I’ve lost a good bit of weight over the past 18 months. I haven’t talked about it much here. It’s bad enough when this starts seeming like an exercise blog; it will not become a weight-loss blog.

That’s partly because the topic is so loaded with cultural baggage. I think there’s pretty good evidence that eating a healthy diet and getting plenty of exercise are both associated with better health. There’s a lot less evidence that being thin is associated with better health—and none at all, as far as I’m aware, that trying to lose weight improves your health, or that exhorting someone else to lose weight improves their health.

Having said all that, my weight is something I’ve been paying attention to, so it seems like something I should talk about here.

What prompts this post at this time is that I’ve reached my lowest adult weight. That is, at 179 pounds this morning, I’ve matched the lowest weight for which I have any record.

I have pretty good data on my weight since 1999. For Christmas that year my brother gave me a Palm III and I installed a weight-tracking app called Eat Watch, which I used fairly regularly from early 2000 until mid 2007. At that point there’s a break in the data, because I lost access to the good doctor’s scale at the Motorola office when the site closed. My bathroom scale wasn’t up to the task. In May of last year I finally bought a good digital scale, and since then I have almost daily data.

Although I’ve been heavier than I’d like pretty much my whole adult life, and have often paid attention to my weight, I’ve largely avoided the curse of yo-yo dieting. Really, there are only two other periods when I’ve lost weight.

The previous one began in 2003. Early that year blood work showed modestly elevated blood sugar levels. The idea that I might break my pancreas was upsetting enough that I took steps: I quit drinking soda and I started running again. From February 2003 through September 2004 I lost 40 pounds, getting my weight down to 188. I kept the weight off for a while; at the end of 2005 it was still around 195, but it was already inexorably rising. By the time the Motorola site closed, it was back up over 200 pounds.

I don’t have much data on my weight from before 2000, but the one exception includes the other period I was losing weight. Back in 1991 I started running, and my running log from that period tracked my weight. I don’t have a value for every week, but I weighed 201 in March that year, and got my weight down to 179 by the end of running season.

In my experience, losing weight is either easy, or else impossible. The easy times are generally summer, when I’m getting plenty of exercise. I’ve tended to blame difficulty in getting exercise for the fact that I gain weight in the winter, but I don’t really have data to show that. It could be other things. Maybe in the dark months I burn fewer calories on incidental movement, such as by fidgeting less. Maybe in the dark months I eat more.

It would only have to be slightly more. One thing the data does make clear is just how few calories it takes to make a large difference. Since May of last year I’ve lost 26 pounds. That corresponds to a daily deficit of just 134 calories. Any little thing—an extra soda, an extra cocktail, an extra beer, an extra snack, an extra serving—would have more than wiped out the deficit. An almost imperceptible change in my amount of fidgeting could easily add or subtract more than 134 calories per day.

It’s pretty much impossible to impose that difference by effort, which is, I think, why diets don’t work. There are extremely complex mechanisms in your body for controlling your weight, which bring to bear powerful forces like appetite and satiety. Making a point of eating less is no more likely to be successful than making a point of breathing less. Losing weight requires changing how you live.

Changes like eating a healthier diet and being less sedentary are likely to lead to weight loss. I used to despair of making such changes. Eating more healthily is tough because (unlike Jackie), I don’t really like vegetables. Being less sedentary was tough because so many hours per day had to be allocated to sedentary activities—sleeping and working.

I’ve improved my diet some. Over the past 20-some years I’ve steadily cut back on the amount of fat and sugar I eat. I’ve also learned to pay more attention to how much food I really want, which lets me get those complex mechanisms for controlling my weight working for me, rather than against me.

Not working at a regular job has helped with being less sedentary—more of my hours are my own. I’ve also made a bit of an attitude adjustment: Before I thought that an hour a day was probably more time than I could afford to devote to exercise; now I figure that 23 hours a day is too much time to spend being sedentary.

Last winter I described a fitness regimen that allowed me to maintain a stable weight. Briefly: Three times a week we lift weights and then do an hour of taiji; the other four days a week I try to walk for an hour. It worked. My weight was stable. (Specifically, from the beginning of September last year though the end of March this year I lost weight at the rate of 0.03 pounds a week, implying a calorie deficit of 17 calories a day. And that right there is a crystal-clear instance of those powerful mechanisms working. Imagine trying to match your calorie intake and activity level within 17 calories by counting calories. It’d be hopeless.)

Maintaining a stable weight over the winter was key. It was perfectly ordinary that I lost weight last summer and this summer. What was different was that I put two summers of weight loss back-to-back.

That’s pretty much the extent of my plan for the rest of this winter as well—a stable weight, so that I’ll be starting from here next summer.

I don’t have much data on which to base a longer-term plan. The National Institutes of Health suggest that the highest healthy weight for a person my height is 164 pounds. That seems like a good medium-term goal.

Looking slightly beyond that, I observe that Jackie is looking very trim these days. To match her body mass index my weight would want to be around 144-151.

That target is supported by my only reasonably specific recollection of my weight from longer ago: When I was a freshman in college, I got mononucleosis. The combination of nausea and a very sore throat resulted in eating a lot less for several weeks, producing considerable weight loss. I don’t have any records, but I’m pretty sure I remember my weight dropping under 150 (which is to say, probably down to 149¾). Despite having gotten there by being sick, I was by no means wasted away at that weight. In fact, I remember looking pretty good.

So, that’s my weight loss story. I don’t expect to talk about it much beyond this. “Let me tell you how I lost so much weight” is just not a useful or interesting story. I only mention it at all because I’ve been paying close attention to it. It would seem to make my own story incomplete to leave it out.

Three miles on the dread mill

I hate running on treadmills. I also dislike running outdoors in the cold. The result has been that, while I may get into pretty good shape in the summer, I always lose that fitness over the winter, because I don’t run.

This year, I’m trying again to run on the treadmill. This year, I’m trying with podcasts.

I don’t listen to my iPod when I run outdoors. Running outdoors is wonderful, and I want to experience it full. Running on a treadmill is awful, and I want to pretend it isn’t happening.

I’ve had to make a second change to make this work: I’m going to the fitness center by myself.

Before, I tried to fit my workouts into the joint visit to the fitness center that I make with Jackie to do our lifting. That didn’t work. Jackie was willing to walk on her treadmill while I ran on mine, but she wanted us to be walking together. Since I was trying to pretend that I had slipped into some sort of lacuna in the space-time continuum, I was an unsatisfactory companion. Jackie was also willing to carry on with her workout while I ran, but there’s no reasonable way for her to stretch her workout to last 20 minutes longer, which is only barely enough time for me to get a reasonable run in.

So far, the scheme is working okay. For three weeks now, at least twice a week, we’ve gone to the fitness center for our lifting, then gone to taiji, after which I’ve gone back to the fitness center to run on the treadmill. The first couple of runs were kind of shaky, but I’d gotten them up over 2 miles last week, and today I ran 3 miles.

That’s long enough, I think. My long runs outdoors had gotten up over 5 miles, but my plan for the winter isn’t to boost my endurance, it’s just to preserve it. If I can run 5–7 miles a week, I think I can accomplish that. A single 3-mile run each week, combined with one or two 2-mile runs, will do the trick.

The podcast thing is working. My plan had been fiction, and I’ve listened to an Escape Pod story and to one on the Small Beer Press podcast. The problem with fiction is that it takes a while to get wrapped up in the story, and every instant that I’m not immersed in the story is an eternity of actually experiencing the fact that I’m running on a treadmill. Music works okay. News podcasts are okay, too.

Once, when Jackie and I were heading into the fitness center, back before we’d given up on treadmill exercise together, I asked her on our way in the door, “Are you ready to face the satanic mills?”

“At least they aren’t dark,” Jackie replied.

“It’s true,” I admitted. “They are well-lit.”

They’re still well-lit. They’re still satanic. But they’re pretty tolerable, if you’ve got a story to listen to.

Physical benefits of standing meditation

Standing meditation is just like sitting meditation, except you do it standing up. (It almost seems topical right now, when so many people are talking about working at standing desks, which is similarly just like working at a regular desk, except standing up.)

I’ve been doing at least a little meditation pretty regularly for three years now, as my taiji instructor spends some time in each class meditating. I have yet to perceive any of the mental benefits that are supposed to flow from meditating. Perhaps I’m just doing it wrong.

The physical benefits, on the other hand, have been remarkable.

Before I started doing standing meditation, I’d gotten a little wary of excessive standing. I’d struggled a bit with plantar fasciitis, and had eventually come up with a multi-pronged approach that included a pair of slip-on birkenstocks that I used as slippers, supportive shoes in general, and limiting the amount of time I spent standing. Together, those tactics had served to keep the plantar fasciitis at bay, without quite curing it.

In the past three years, since I started doing taiji, something has completely cured the plantar fasciitis. Maybe it was the taiji, rather than the standing. Maybe it was the running, walking, and other exercise I’ve gotten. I’ve lost some weight, and that’s bound to have helped. But I’m inclined to credit the standing with a good bit of it.

I think this is true, even though I think I was also right to be careful about excessive standing, because standing meditation is not just standing. Standing meditation is standing with focus. Our instructor emphasizes that we’re not thinking about anything in particular, nor are we doing anything in particular (except standing), but we’re ready. We’re actively ready for whatever happens.

Standing with this sort of intention is very different from standing while doing something else. While we’re standing, we making an explicit effort to identify and relax any muscles that we’re using beyond the minimum set needed to keep us upright. I doubt if a cashier who has to stand for an eight-hour shift would get similar benefits.

Maybe I’ll eventually get some of the other supposed benefits of meditation. In the meantime, I’m happy to settle for just this one.

An open-ended run

Yesterday, I went on my first open-ended run of the season.

On earlier runs, I pretty much knew how far I was going to go and what route I’d follow. Occasionally there’d be a bit of room for variation—I might think, “If I’m feeling good, maybe I’ll add a second lap around Kaufman Lake,” or “Maybe I’ll add the leg out to Bradley and back.” But by and large, I knew to within a few tenths of a mile how far I’d run before I took my first step.

The reason was that every run would take me a large fraction of as far as I could run. There was no chance I’d just decide on a whim to go a few miles further, because I couldn’t run a few miles further.

So, it was a great treat yesterday, to head out for a run with only a general idea of where I’d be running, and with no specific plan how far I’d go.

I knew I’d run halfway down O’Malley’s Alley (the short bit of rail trail that I call McNalley’s Alley), and then cut over into the neighborhood south of there. But I’d had only a vague, somewhat aspirational notion that I’d continue on as far as the trail through Robeson Park. But I knew that the trail would cross several different roads, and that I’d be able to head for home on any one of them, if I decided that I’d run as far as made sense.

In the end, I headed home when I got to Crescent. On some future run, I’ll push on as far as Mattis, and maybe continue on down the Simon trail before heading home.

This run, according to my GPS thingy, came to 4.84 miles, which I ran in 54:15, for an average pace of a bit over 11 minutes per mile. And it was a great run. My feet didn’t hurt, nor did my ankles, knees, hips, or any other bits. I did get pretty tired by the end, but not over-tired. In fact, after a bit of a rest and rehydration, I had enough energy to bicycle 9 miles, lift weights, and do an hour of taiji. (The lifting, I must admit, was a rather feeble effort.)

At over 50 minutes, it was definitely a long-enough endurance effort to produce significant levels of endocannabinoids, which I presume is the reason that my memory of the run is mainly just a strong sense that I was having fun and feeling good. There are only a few spots where specific details are sharp and clear—the spot where I had to back up and run on the grass next to the trail, to avoid a muddy patch, the spot where I thought, “There’s a hill here? How did I not know there was a hill here?” and the spot where I slowed to a walk so I could look back over my shoulder and read a street sign, so I’d be able to make a map.

Speaking of which, here’s a map of the run:
