A long walk on the Kickapoo Rail Trail

The Kickapoo Rail Trail had its ribbon-cutting Friday. Jackie and I attended as volunteers for the Champaign Forest Preserve District. We walked a short distance that evening, but our feet were tired after spending a couple of hours passing out flyers and listening to local dignitaries speak, so we cut that walk short.

We returned on Sunday to make a proper walk of it.

We parked at the Urbana WalMart (which has said that it’s okay for hikers and bikers to park there, as long as they park in the northwest corner, which is where you’d want to park anyway).

Then we hiked pretty much the whole trail: From High Cross Road to the end of the trail in St. Joseph and back again. We had lunch at the Wheelhouse, a pretty good restaurant in St. Joe that’s right there on the trail, and is appropriately cycling-themed. The only part of the trail that we didn’t hike is the short stretch west of High Cross Road that runs to Main Street where it nips up to University.

It’s a great trail. As Jackie and I discovered when we hiked the Kal-Haven trail, that crushed limestone is a great surface—hard enough for even a skinny-tired bicycle, soft enough to be gentle on feet that are going to be getting a pounding over a long hike, relatively cheap and easy to maintain.

There were a lot of cyclists out on the trail; they outnumbered the walkers by maybe 20 to 1. I guess that makes sense. The round trip is over 13 miles, which puts it up close to what I consider a very long walk (anything over 14 miles), but quite a modest distance for a bicyclist.

Sights along the trail include this spectacular view from the bridge over the Salt Fork:

There are supposedly river otters along the Salt Fork now, according to the text on this sign, but we didn’t see any. (“They hide from you,” says my brother.)

We will be back to bicycle the trail very soon. I don’t know if walking it will be a regular thing or not, but at a minimum we’ll get out to walk the stretch west of High Cross Road that we haven’t done yet.

My dad has fond memories of the old rail right-of-way from when he was a grad student (this would have been the late 1950s) and his advisor brought students out to there to see prairie remnants. Seeing this land properly preserved is wonderful, and I’m very much looking forward to the expansion of prairie species along the path that will follow with proper management.

We’re very excited about future plans for the trail. It’ll be years before it connects all the way to Danville, but there are bits that’ll probably get done sooner—trails heads at Weaver Park and Kolb Park, a short extension that will take it a few blocks further through St. Joseph (to the road to Homer Lake).

If you’re local, you should get out and bike or walk it at your next opportunity. It’s a wonderful trail.

High-intensity workouts good for aging mice

Starting with sedentary mice aged about 65 in mouse-years, half were put on a program of high-intensity interval training:

the interval-trained mice seemed in many ways younger than they had been at the start. In particular, they were stronger; when pulled backward gently by researchers, they would cling to a bar longer than at the start of the study. They also had greater endurance capacity, as well as more muscle mass in their hind legs than the sedentary animals, and they scampered faster. Few now were frail.

Feeling good versus feeling young

A friend of mine posted to her Facebook page recently criticizing a whole category of ageist comments along the lines of “You’re only as old as you feel.”

It caught my interest in particular because I’d been mentally composing a post about how I just turned 58, but I’m not suffering the aches and pains that supposedly go along with getting old. My friend’s post reminded me that referring to this as “feeling young” is problematic. And yet, I find that I come down on the other side of this issue. Sure, there is a certain irrefutable accuracy to say that your age is the current year minus your birth year, but age is many things besides a mathematical calculation—at a minimum it’s a social construction, and also perhaps a collection of biological circumstances.

It’s true that what I mean—and what perhaps I should say—is I feel good. Better, in fact, than I’ve felt in years. I’m stronger, more flexible, and more agile than I’ve been in longer than I can remember. I move with more ease, more power, and more control. I have more endurance. I’m certainly more comfortable in my own skin.

A lot of this is just good luck, of course—good genes, avoiding serious injuries and serious illnesses so far.

Beyond good luck I credit my movement practice for most of the rest. Taiji. Walking and hiking. Running (merely an adjunct, but one I enjoy in particular). After years of lifting with machines to little noticeable effect I now do almost all my strength training with bodyweight exercises and am having much more success. (The main exception to pure bodyweight exercise is doing kettlebell swings for my high-intensity interval training, which I ought to write about because it seems to be doing some good, and is also quick and fun.) Push hands I wrote about recently. Animal movement ditto. So new I haven’t had a chance to write much about it yet, I did yoga for the first time last week.

But to bring this back full circle, I’m not so sure that it’s wrong to talk about “feeling young.” My friend is right—growing old is a privilege not everyone enjoys. It is indeed better than the alternative: dying young. But just as I can see her objections to denying age (as if refusing to acknowledge it meant something), I object to denying one’s felt experience. If someone says that they “feel young,” does an appeal to mere arithmetic justify correcting them?

Certainly I am not the only person to feel this way. There are always people trying to express health and fitness in terms of age. There are websites that will suggest a guess as to your physiological age vaguely based on your weight and your activity level. Various practitioners of various disciplines will measure specific things ranging from your maximum heart rate to the length of your telomeres and use the results to calculate a biological age.

They’re all pretty dubious, but I find that I do not object in principle to thinking and talking about concepts like health, fitness, and vitality in terms of age. Even though there are many unhealthy young people and many old people who are fit and vital, I think the notion resonates in a useful way.

As for me, I feel good. I also feel younger than I’ve felt in years.

Heart rate training and this morning’s run

Another quick experiment with WP-GPX-Maps, but also a quick report of using my heart rate in my running training.

First, here’s this morning’s run:

Total distance: 2.83 mi
Total Time: 00:37:44

Roughly the same route as last time, except that instead of running back past the woods the same way I ran out I ran back on a path through the woods itself, and then I added another out-and-back through the prairie, out on the path we call the Low Road and then back on the Middle Way, adding a half mile or so.

(By the way, my heart rate ought to be showing up and isn’t. Part of the reason it’s not there is that it’s not being included in the GPX file that I’m getting from Polar. I was able to get a GPX file that included the heart rate, by exporting a TCX file from Polar and then converting it using TCX Converter, but that still didn’t work. The result was actually worse, in that it lost the altitude data as well. The map above is generated from the straight GPX file from Polar.)

I’m trying to train at my MAF heart rate, which I calculate at 127.

The theory here is that training at this intensity is best for improving your ability burn fat (rather than glucose) for energy. At higher heart rates you end up using a great deal of glucose, so you end up glycogen depleted and then have to eat carbs to replenish your stores. At this lower intensity your consumption of glucose is modest and easily replenished with even a low-carb diet.

With regular training, you gradually get faster at this low intensity (for a while, anyway), which means that you’re automatically training for both speed and endurance at the same time.

I have a heart rate monitor from Polar which works great, except that (incomprehensibly) the Polar app doesn’t have alerts to let you know when you go outside your target range. I’ve been trying to learn through trial and error to feel the intensity level that gets me to the target HR.

This time I got it just about exactly right.

Polar has its own idea of target range, and the closest they have to the zone I want (which is 117 to 127 according to MAF) is what Polar calls Zone 3 and pegs (for me) at 115 to 131. I did 92% of this run in that zone. And, judging from eyeballing the graph, a lot of it was just under 127, right where I want it.

I also squeezed in a 20 minute lifting session after my run. The HR data from that is also kind of interesting, but also doesn’t display with the WP-GPX-Maps plugin.

Open workout tracking

I really like to gather and play with data from my workouts, but I dislike the way the tools I use to gather it tie me to their own websites for analysis and display—and in particular the way they always want to spin up their own scripts on my website when I want to display the data here. So, via Srikanth Perinkulam, I’m experimenting with WP-GPX-Maps as a way to display a workout with less use of closed software. This is a test:

Total distance: 2.32 mi
Total Time: 00:28:34

That’s my run from Thursday, along my most common route for a short run: Out on sidewalks along Curtis Road and First Street (around “The Place), and then the rest of the way on trails back through the Lake Park Prairie (along what we call the High Road—on top of the berm along the north edge of the prairie), over the weir across the creek that feeds into the Embarras River, past the little pond and down along the west and south sides of the Lake Park Woods, and back again across the weir.

If you’re a reader of this blog, your opinion is earnestly sought: Is that better than the workout sessions I used to share via Endomondo? Or did you never object to the closed tools in the first place? If you simply have no interest in my workout tracking data, that’s okay too.

Here’s one more test, the hike Jackie and I took at Forest Glen on June 11th:

Total distance: 5.56 mi
Total Time: 02:36:31

Replied to:Expanding my movement practice: Animal movements | Srikanth Perinkulam

I just took my own first yoga class!

I’d meant for years to study yoga and hadn’t managed to make it happen, but this week the stars aligned: one of my neighbors is a yoga instructor and is starting an outdoor class right here on the lawn at Winfield Village.

This sounds pretty interesting, Philip. Something I should consider adding to my workout regimen. I’ve always had a tough time coordinating my limbs and following flow sequences. Several years back after a failed attempt at learning Kalaripayettu , I was heavily demoralized. My flexibility seemed to be abysmally low and I had a real tough […]

Expanding my movement practice: Animal movements

My most recent addition to my movement practice, just started, is animal movements.

These are basically just ground exercises where the shapes are inspired by animal movements: Bear and Crab crawls, Ape and Duck walks, transitions from one to another.

Playing on a fallen log at the Nature Playscape at Homer Lake

My hope is that doing them will help me connect some of my mobility practice with movement (as opposed to static stretches). My hip mobility and my toe and ankle dorsiflection are limited enough that I can’t do certain things that I’d like to do—in particular a deep squat, but also a particular kneeling-to-standing transition. Probably other things I can’t think of at the moment.

For three years I’ve been working on these aspects of flexibility/mobility and I’m making progress, but I’m not there yet. I’m not sure what it will take to get there, but one possibility that comes to mind is that I haven’t tried to connect these things with other movements. I’ve done isolated stretches, and I’ve done assisted/bolstered versions of the movements, but I haven’t tried to use the movements as part of a sequence of other movements. Very possibly my difficulty is not merely my muscles being “too tight,” but rather springs from a the lack of a proper mind-body connection linking these moves and other moves I do.

My hope is that the animal forms, by giving me an opportunity to pass through these postures (rather than merely trying to hold them as static stretches) may help make the mind-body connection in a way that lets me relax into the postures quicker than just more stretching would do.

In any case, I’ve been meaning for a long time to increase the amount of ground exercises I do and not getting around to it, and animal movements—by giving me a framework for that—have finally gotten me started.

I don’t think I’m going to stick with the animal forms for long. There are plenty of natural human ground movements which are largely similar, but some of the animal forms modify them to justify the name, and although that can be fun, my own affinity is always going to be for natural human movement.

Still, tolerating the silliness can lead to impressive results in terms of power and control. Check out for example, this video of movement guru Mike Fitch demonstrating what an animal movement practice he calls Animal Flow looks like:

Once I’ve established the habit I’ll look to transition away from animal forms and just do combos of human-style crawling, rolling, sitting, squatting, kneeling—and the transitions between them.

Expanding my movement practice: Push hands

I haven’t written much yet about adding push hands to my movement practice, mainly because I don’t feel competent to describe it well.

Push hands is a taiji training technique—a way to learn how to accept and redirect force. I view it as falling roughly at the midpoint between taiji as moving meditation and taiji as a martial art.

My taiji teacher wasn’t really interested in push hands, I think because he wasn’t really interested in the martial aspects of taiji. He did give us the barest exposure to pushing, so I wasn’t a complete novice, but nearly so.

I am interested in the martial aspects of taiji, so I was delighted last year when I met a couple of people who were interested in pushing. We got together several times last fall, then let our training fall by the wayside over the winter, but started meeting again once the weather turned nice in late spring.

One of the friends I push with describes push hands as a test or diagnostic for your form practice: If your form practice is sound, you will be good at push hands.

Already my push hands practice is informing my form practice, as I learn to shift my weight to move, but simply to turn my waist to accept and redirect energy. I’m trying to learn to keep my shoulders down (a work in progress), and I’m trying to learn to keep my arms and shoulders connected to my core (same, but with less progress).

Great fun.

Free group tai chi practice

Free tai chi group practice: Monday/Wednesday/Friday at 8:30 AM in Morrissey Park!

A bunch of my students from the Savoy Rec Center (and a few other people) meet in Morrissey Park over the summer for free group practice sessions. There’s no teacher, but plenty of folks are willing to demonstrate moves—we’ve had several people learn most of the 48-movement form just by coming all summer and asking people, “How does that next move go?”

A typical hour includes 30 minutes of moving qi gong, 10 minutes of standing meditation, one or a few short forms, and then the Chen 48-movement form.

We meet Mondays, Wednesdays, and Fridays from 8:30 AM to 9:30 AM in Morrissey Park. We generally gather south and west of the tennis courts.

This year we’re starting Monday, June 5th.

Because there’s no teacher there’s no one to make an official determination that it’s too rainy for class—just decide for yourself.

Off all meds

For years I took drugs for high blood pressure, and for almost as long for allergy symptoms. This post is just to mention that going low-carb has gotten me off all of them.

I got off the allergy meds first. I got on them gradually. For years I said I didn’t have allergies. Then for years after that I said, “Well, for a couple of weeks in the spring and a couple of weeks in the fall, I get a little snuffly.” Then I started being snuffly all spring and all fall. At some point I started taking antihistamines (Claritin seemed to provide the most symptom relief with the least amount of drowsiness), and then at some point I started taking Nasacort as well, to manage congestion that otherwise made it impossible to breathe through my nose.

I initially went low-carb specifically to get off the allergy meds. Without the Nasacort I often had to breathe through my mouth—unpleasant, but also a genuine safety hazard while eating.

It worked, and it worked very quickly—in about three days I was off the allergy meds.

Getting off the blood pressure meds (lisinopril) took a while longer, although I saw improvement almost as quickly. Just a few weeks after going low-carb, prompted by some postural hypotension, I cut the dose I was taking first by half, and then by half again.

I remained on that one-quarter dose for about a year. But two months ago the postural hypotension returned. So, in consultation with my doctor, went ahead and stopped taking the bp meds altogether.

I’m especially glad to be off the Nasacort, which although supposedly a topical steroid is known to have systemic effects in at least some people. Claritin is probably not associated with Alzheimer’s (because it is non-drowsy), but people haven’t been taking it long enough to be sure. I’m sure glad I took the lisinopril—I don’t want to think about the shape my heart and kidneys would be in now if I’d had uncontrolled high blood pressure for the past 25 years—but I’m glad to be off it now.

I no longer have to deal with the common side effects (or worry about the rare side effects). I no longer need to make the monthly trip to the pharmacy. It’s going to make things like traveling easier—not to have to carefully pack up the necessary doses for each day of travel, not to have to worry about getting separated from my meds.

It’s a really nice feeling.
