Since spring I’ve been using some workout plans put together by Anthony Arvanitakis. For eight weeks from late May to early July I did his Superhero Bodyweight Workout, and since then I’ve been following along with bodyweight workouts he’s been sharing for the summer.

One limitation that I’ve had all this time is that I haven’t been able to do the hill or stair sprint workouts that he suggests, due to a lingering foot injury. After repeatedly resting my sore foot until it was nearly all better, and then trying to get back into running, only to have my foot start hurting again, I finally took a full month off. That was enough for my foot to finally feel entirely better, so last week I went for a 3-mile run as a test. My foot didn’t hurt during the run, but was sore again that evening and the next day.

I took another week off from running, and then today decided to try a different tack: Those hill-sprint workouts.

Three things about this make it make sense to me:

  1. Hill sprints are lower impact than running on flat ground (because the ground is higher for each next step, so your foot doesn’t fall as far).
  2. The total mileage is much less (today’s workout was just 0.5 miles).
  3. My running gait is better when I’m sprinting.

Putting those things together makes me think that maybe hill sprints will let me run at least a little without aggravating my foot injury.

Another thing I’m doing is extending my warmup quite a bit. I did my full dynamic stretching routine before heading to the workout location. Once I got there I scrupulously followed the prescribed warmup routine, jogging up the hill at 50%, 60%, 70% and 80% intensity (I actually did 5 preliminary jogs up the hill, at gradually increasing intensity). After each of the last two warmup jogs I did a set of 12 straight-elbow push ups (what I call rhomboid pushups) as preparation for the pushup part of the workout.

The main workout then was 4 sets of sprinting up the hill at 90% intensity, walking down, and then doing as many pushups as I could do with perfect form (I did 10, 10, 8 and 8 pushups).

I also did something I’ve always resisted in the past: I drove to my hill. (This being central Illinois, hills are few and far between. My hill is at Colbert Park.) Usually I don’t like to drive somewhere to get exercise—why not walk or run and thereby get more exercise? But with my sore foot, that much extra running would definitely aggravate the injury. Even walking that far might be an issue.

One thing I need to be careful of is to be sure to get in my full wrist warmup. I’m pretty good about that ahead of a rings workout, but perhaps wasn’t as scrupulous as I should have been this time. But the pushups put enough stress on the wrists that it’s good to get them fully warmed up even before the rhomboid pushups.

I’m pretty pleased with my workout. My foot (really my ankle) is a bit tender this evening. We’ll see how it feels tomorrow. On the schedule I’m (tentatively) following, I’ll be doing hill sprints again Monday. If my foot is completely pain-free at least several days ahead of that, I’ll proceed with that plan.

Jackie was fixing blue-corn pancakes with maple syrup for breakfast, and eating that many carbs first thing in the morning can be a problem for me. However, I have come up with a strategy for dealing with it: Getting in a pre-breakfast fasted workout. My theory is that by doing this I deplete my muscle glycogen, so that my muscles are primed to soak up all the carbs I eat, minimizing the degree to which the glucose spikes my blood sugar.

I have no data to show that this works, but anecdotally I can report that it seems to help.

I’ve been wanting to go for a run. I had planned to go for a run yesterday, but it ended up being rainy enough that I decided to postpone the run for a day. So I might have gone for a run for my pre-breakfast workout, but Jackie was hungry early, and I didn’t want to delay breakfast by an extra hour.

So, I did what’s becoming my standard HIIT workout: I warm up with 3×25 Hindu squats, and then I do 3×25 kettlebell swings with my 53 lb kettlebell. It’s a quick workout—it’s all done in 20 minutes, including some amount of pre-workout warmup—and it’s of high enough intensity to burn off plenty of glucose.

After breakfast (and a bit of digesting) I went ahead and got out for my planned run. After the persistently sore foot I’ve been dealing with for months now simply refused to get better, I had taken a full month off from running to see if all I needed was plenty of rest to fully recover, and that may have done the trick—I went out for a 3.33-mile run, and I had no foot pain whatsoever.

I don’t wear my Oura ring for the kettlebell workouts (or other workouts where I have to grip something, because handles, bars, and (gymnastic) rings don’t play well with the Oura ring). However, my Polar heart rate monitor will tell Google Fit about my workout, and the phone app for the Oura ring will read that data and give me credit for what I did while the ring was off:

My peak heart rate during the kettlebell swings would have seen me to much higher activity levels than the just-barely “High” levels shown, but that’s because it’s an interval workout. A set of 25 swings takes me just about 50 seconds, and then it takes about 3 minutes for my HR to drop low enough that I can do another set. The software is averaging those periods together. Unless I’m doing sprints (which I didn’t today) a run is just a steady-state effort. I try to keep my HR down in the MAF range, but didn’t manage it today (because of the prior HIIT workout).

I’ve had a slightly sore foot for a while now.

It hasn’t been a big deal. It doesn’t hurt when I run. It doesn’t hurt when I walk (except sometimes when I walk really fast). It doesn’t hurt when I stand, or when I’m just sitting.

Mostly it hurts when I use my foot as a brace to turn or twist, such as when I brace the side of my foot against the mattress to turn over in bed. Sometimes it hurts when I’m standing on my other foot, and touch just the toe of the sore one down to catch my balance.

It sometimes hurts for the first few minutes right after I get up in the morning, kind of like plantar fasciitis, but a different part of my foot: the medial edge, just posterior to the ball of the foot.

Even then, it doesn’t hurt much.

However, it has been persistently hurting occasionally, just a little, for a long time now. Months.

I had been doing basic, conservative care. I was wearing supportive shoes, avoiding things that hurt it as best I could, and figuring it would eventually get better. But it hasn’t.

So, a couple days ago, I decided to step it up a notch: I decided to treat it with a placebo. (The effectiveness of placebos is well-established. They’re effective even when people know that the treatment is a placebo.)

My initial plan had been to add in some sort of cream or ointment. I thought of something like Aspercreme, but it doesn’t hurt enough to justify the use of even a mild analgesic, so I thought I’d get something like Bengay or IcyHot: just some sort of counter-irritant that would make it clear that I was “doing something” to treat my foot. Then I saw Walter Jon Williams’s recent post on Tiger Balm, and knew that I’d found the right stuff.

Jackie discovered Tiger Balm several decades ago, during her travels in Asia, and it has long been a staple item in our medicine cabinet, but we’d let ourselves run out in the run-up to our several moves, so we didn’t have any. Fortunately, the closest store to our townhouse is a CVS, and they had two varieties of Tiger Balm in stock. They seemed almost identical (a one-percentage point difference in menthol), but the one they were marketing as their “ultra strength” “sports rub” was $1 cheaper, so we got that one.

I’ve been using it for two days now, and I’m imaging that my foot is feeling better.

Perhaps because I’m finally doing something about my foot, I also remembered something else. For years now I’ve been wearing a pair of slip-on Birkinstocks as slippers. I started wearing them when I first got plantar fasciitis, and found that it was crucial to never go barefoot on our hardwood floors. Along with other supportive footwear, they solved the problem.

Usually I only wore them indoors, but very occasionally I’d wear them outdoors for very short trips—if I was only going as far as the mailbox, for instance. One or two summers ago, I tried to wear them for a walk around the block, and found that they really hurt the joint at the base of my big toe. I couldn’t make it even as far as around the block—I had to turn back and hobble home.

They never hurt my foot when I just wore them around the house, which I continued to do.

But now that I was thinking about it, it occurred to me that maybe they were hurting my foot, just not enough to notice unless I did something out of the ordinary.

Since the plantar fasciitis hasn’t bothered me since I started doing taiji, I decided to retire the slip-on Birkinstocks.

I’m also adding some calf-stretching, as well as some calf and shin strengthening activities.

I suspect some combination of those activities will do the trick. But just in case, I’m also rubbing some Tiger Balm two or three times a day into the side of that foot, from ball back almost to the heel.

I’ll keep you posted.

Oh, and by the way—the main reason I haven’t been posting much here is that I’ve been posting most of my exercise-related stuff on my Esperanto language blog, mostly as a way to improve my grasp of the exercise-related vocabulary (which is surprisingly poorly developed in Esperanto). I have a sense that most of my friends and relations have heard about all they want to about my exercise and fitness. And what better way to make sure almost nobody is bothered by my yammering on about it than to do so in a language almost nobody speaks?
