This entry is part 63 of 72 in the series My Journey

Somewhere in my 30’s, slowly, year by year, the frequency of my back problems increased. I’m not talking about, I helped a friend move over the weekend, or, I did climb-ups for an hour at Parkour class, and now my back is “out.” I’m talking about,

I sat down to put socks on — because I cannot hold my foot up to reach it standing — and my lower back “just” gave out.

or,

I was just standing at the sink washing dishes.

For me, these incidents where I was clearly not doing anything amazing and was still somehow injured, became a clear sign that I needed to change something. In hindsight, this is the article I wish I had found first and so I hope it helps someone.

Elsewhere, in my Changes and Results series, I’m laying out all the big things I’ve changed, project by project. But there was never any one thing that I worked on specifically to fix my back. It simply turned out that many of the things I did contributed to — knock on wood — resolving my back problems. Of course my back still gives me trouble when I deserve it. But these days, I know when it’s going to be a problem. I can feel when my back is getting tired, and if I listen to that quiet signal I can avoid the worst of the problems.

My spine and me

Although I had been doing some intentional, general improvement efforts, such as losing weight and getting better sleep, my back-focused improvement journey really began when I heard Ido Portal say something to the effect of:

Your legs are for moving you through your environment. Your arms are for manipulating your environment. Your spine is for orienting yourself within the environment. So your spine should be this incredibly mobile and powerful system with a huge range of dynamic movement.

(That’s not an exact quote because I don’t feel like going through the entire “Rewild Yourself Podcast” episode where Daniel Vitalis interviewed Ido Portal. It’s episode number 8: Ido Portal on the Movement Diet which you should probably go listen to.)

When I heard that, I realized that my spine was nothing at all like Ido’s vision of a human spine. Mine barely moved at all, and when it did, I often felt nervous about impending disaster. After hearing Ido’s way of describing the spine, I had this new perspective where each time I’d do some movement, I could see how much my spine was right at its limit of ability. I realized that my spine should be an incredibly varied mover, and that my spine’s flexibility (the total movement possible) and range of motion (the smaller space of movement where my back is usable, comfortable and strong) are critical, foundational elements to all of my health and movement.

I realized that for years I had tried to “stabilize” and strengthen my spine as a defense against movement causing injury to my back. But I now see that this is an erroneous reaction to weakness. If instead of being immobilized as a defense, my spine is strong, then it can be mobile, able to make all the movements I need, and not be injured.

Awareness and honesty

The first step was to learn to avoid injury. This sounds trivial, but it was not at all obvious to me at the time. When I was so fat and inflexible that putting my socks on regularly endangered my back, it was a terrible, humbling experience to admit that I had to change how I put my on socks.

I had to identify all the landmines, and own up to them. I had to learn that stretching — really just moving around — was mandatory each morning. I had to stop automatically rushing to help everyone move heavy objects. I had to stop trying to be “the strong guy,” and generally dial down all my activities to a level my back could handle. I had to acknowledge those random days when my back felt “off”, and learn to take a rest day for recovery.

All of which forced me to face that I was no longer indestructible and to own up to the deteriorated state of my body. Awareness and honesty were the only way that I could stop taking frequent steps backwards. They were the only way that I could begin to make glacial forward progress.

(I’ve written more about the Philosophy of the changes I’ve made in my Changes and Results series.)

Weight loss

Losing weight is obviously not easy. But every pound that I peeled off paid dividends to my back. It turns out that weight around your middle drastically increases the load on your lower back. “Lost weight” is a woefully inadequate summary for this element of fixing my back, but hopefully I’ll get around to writing out everything I did to lose weight.

Recovery work

What began as endless massage work by my spouse, slowly morphed into self-massage and then into mobility work; Basically, I learned to lay on the floor moving in all the ways my spine was meant to move. I mastered the use of a foam roller and Lacrosse ball for myofascial release and self-massage. As my back got stronger, I was able expand this recovery practice to a more general, whole-body movement, stretching and — much later — general strengthening.

(I’m writing a separate post on my “20 minutes of morning stretching” which is one of the cornerstones upon which I have built the whole new me. It’s not yet published, but will eventually be part of my Changes and Results.)

Finally, chiropractic has saved me countless times. I know many people who believe chiropractic is quackery. But for me, it doesn’t matter how or why, it simply yields results.

Posture

Years of sitting, and progressive weakening of my back, took their toll. Worse, the hunched back, rolled shoulders posture was so common in my environment, that it seemed normal. So I didn’t even realize what was happening to me.

The first baby step to improving my posture was when I learned how to understand, and control, the orientation of my pelvis through learning to sit as part of martial arts training. The traditional Japanese seated posture, seiza where you sit with folded-under knees and pointed toes is great for learning posture. Of course, this type of sitting initially rewards you with agony from the knees and ankles. But once your legs adapt, there is a delightful feeling of peace and centralized weight when you learn to center your pelvis and to balance and align your entire spine. But maintaining this alignment, even in a statically balanced seated position, required a certain muscle tone. A tone which I had lost through endless sitting in a poor posture.

I soon realized that the orientation of the hands as they hang at your sides is indicative of your upper back posture. Palms turned to the back, (the shoulders being in interior rotation,) with that “knuckle-dragger” appearance is a sign of a week upper back and poor scapular position. I began incorporating various exercises, (the ‘Sphinx’ pose from yoga, ‘shoulder dislocations’, and thoracic extension in supine position, etc.) into my daily recovery work. (For a great introduction, read De-Quasimodo Yourself.)

As I’d gained weight, I hadn’t realized that I had also, slowly transitioned to a “dumped” lower abdomen: guts hanging out the front, pelvis tipped forward, and lumbar spine pulled forward into a maximum arch. This led me to lower back agony whenever I spent time on my feet, especially if I over-worked my lower back by strolling and slowly shift my weight from one leg to the other. But as I’ve lost fat from my typical abdominal male pattern, and as running and jumping in the context of parkour have strengthened my glutes, it has become easier to maintain a neutral pelvic position and a neutral curve of my lumbar spine.

Walking

Solvitur Ambulando ~ It is solved by walking

Today, I have a ton of stuff here on my site about walking.

But it all started, long ago, when I read a blog post by Steve Kamb, about Walking to Mordor. “One does not simply walk into Mordor!” Except, that is exactly what Sam and Frodo did. Elsewhere I’m writing an entire post about my efforts and progress related solely to walking; But all of my walking was kick-started by Steve’s Nerd Fitness blog post.

Shoes

This was the least obvious thing which improved my back: The closer I get to living barefoot, the better my back feels.

Long ago, I was wearing “normal” shoes, and then I started taking some parkour classes. Turns out that I want to wear the lightest weight, and thinnest soled, shoes I can; because I want to use my feet and toes. Anyway, roll with me here when I say: I wanted to wear minimal footwear for parkour. So, I started wearing Feiyue shoes to class — not the fancy French brand of shoes, but the el’cheapo, crépe sole, martial arts shoe. They have no structure, no arch, and just some padding and protection from most (not all) things you might step on.

I started to run in Feiyue. I ran 10 feet and my calves cramped up. I kept at it. For years. I relearned how to run. Then I relearned how to walk. Then I relearned how to use my knees. Then I realized that to get things working again, I needed to stop wearing “normal” shoes entirely. So I started wearing Feiyue everywhere.

I went on reading about feet. …and about minimal shoes. …and about barefoot training. Then I learned about the amount of nerves in our feet, (the same as in your hands,) and I had some discussions about sensory input through your feet. …and balance. …and acupressure points.

It is not an exaggeration to say that learning about my feet has changed my life.

Today, I exclusively wear an old-school track running shoe called Bullets, made by Saucony. I remove the insoles, so that from the midsole to the toes there is ZERO padding; just a few millimeters of hard rubber sole between my foot and the world. I wear these same shoes for everything. All surfaces, all activities — everything.

The ah-ha moment

It was at this point — after all of the above changes, and after I had spent about two years full-time in minimalist shoes — that I realized my back was fundamentally different.

Then I set out to write this, over the course of 18 months. :)

§5 – Sleep →

Published September 13, 2017  ·  All posts on Sep 13  ·  ,

This entry is part 5 of 13 in the series Changes and Results

Q: I’ve been entirely preoccupied by a most frightening experience of my own. A couple of hours ago, I realized that my body was no longer functioning properly. I felt weak, I could no longer stand. The life was oozing out of me, I lost consciousness.

Picard: You fell asleep.

sigh Sleep. Sweet. Rejuvenating. Blissful. …when you can get it.

Preamble

There is a huge amount of information about sleep available on the Internet. Over the years, I’ve collected a wide range of references upon which I’ve based my actions and opinions. I do this for a lot different topics, and I have a companion web site where I collect all the health related information I’ve found. In the case of Sleep, please see Sleep Quality, Light Sensitivity in the Human Brain, and Magnesium and Sleep over on Hilbert’s Library.

Darkness

I sleep best in complete darkness.

Long ago, I had no idea that light was messing up my sleep quality. Light is everywhere in modern life: it comes from windows, from doorways, from the alarm clock’s LED numerals, from the blinking LEDs on the WiFi router. But, after a lot of reading, and over ten years of experimenting, I’m convinced that light is enemy number one.

Sure there are other things which will wake me, (noise, movement, etc) but light is pervasive. Light is subtle. Light is insidious. Rage! Rage against the light!

So the goal for me is complete darkness.

Aside: Yes, I’ve considered using a sleep mask to cover my eyes. However, the human brain is broadly sensitive to light, so I’m not convinced a light mask is as good as a good old-fashioned dark room. See Light Sensitivity in the Human Brain.

My life is organized around the time on the clock, so I do not have the luxury of arranging my sleep around the sun’s rise and set. Therefore, I needed to manipulate my environment. When I began hacking my sleep at our apartment, my first light source to tackle was a street light that completely illuminated our bedroom through a high window in our cathedral ceiling. I had to buy a tall ladder just so I could climb up and cover the entire window with cardboard wrapped in velvet. Although we only had nearly-useless mini-blinds on all the other windows, this first light-reduction hack made an improvement in my sleep quality.

When we bought a house, the bedroom was the first room we remodeled. We set it up to be PITCH BLACK. The alarm clock is dimmed, there are no chargers or electronics in the room, and I added black-out curtains to the windows. Each night, when I first lie down to sleep, I cannot perceive a difference between having my eyes open or closed. (Of course, by the middle of the night, my dark adapted eyes can easily tell the difference.) If I step out of the bedroom in the wee hours of the night, the rest of the house seems so bright! There’s a light on the smoke detector, all the windows admit outside light, the microwave’s clock, the standby light on the TV, and on and on.

So my first suggestion is to get as close as you can to pitch black. Change things, move things, buy things, whatever — sleep is the most important part of your life.

The alarm clock

Initially, I had a generic alarm clock… beep beep beep BEEEEP! There’s nothing like waking up with a shot of adrenaline and cortisol to start me off on the wrong foot for the day.

First, I changed to an alarm clock which played music, but it had blindingly bright green numerals. Eventually I read about alarm clocks which have a bright light which slowly — over a half hour — fades up to fully illuminate the room. (Search for “Philips HF3470”; It’s discontinued, but it will get you going in the right direction.) Some mornings, the fact that “the sun has come up” in the room is enough to wake me up. But usually, the alarm clock proceeds to an audible alarm, and ours urges us by playing various tweeting bird sounds. (If I wasn’t so deaf, the light would probably wake me up enough to hear the actual birds outside.)

When to sleep

If you have all the above under control, you can technically sleep at any time of day. But there’s a catch: You need time to physiologically wind down before going to sleep. If it’s bright daylight when you want to sleep, you’ll need to craft a dimmed, calm space where you can relax and wind down. (But not where you actually sleep, don’t lay on the bed to wind down. More on not making your bed a multi-use space below.)

Consistency in sleep times is key. There are physiological processes which occur in the body which are not under conscious control. The body works on habit (and environmental cues) and it’s sluggish about changes. Wonky work shifts that make you change your sleeping patters are not healthy; if you’re into that type of work, just realize you’re trading your quality of life to accomplish your job. Be sure it’s worth it.

Remember: For me, sleep is the most important thing in my life. Work, play, scheduling, consistency… these are all things I’m will to work on, hack on, and change, to improve my sleep schedule because poor sleep leads to a poor life.

Temperature

Slightly cooler works for me (and agrees with what I’ve read.) But it doesn’t seem to matter too much. As long as you’re comfortable. But if the temperature is consistently UN-comfortable, you need to correct that.

There are obvious ways to hack the temperature, (e.g., air conditioning, a fan,) but you can also hack the general room environment. Figure out where the air moves through the room. (For example, if air normally moves from your open window to the door, move your bed to be near the window.) Get creative and sling a hammock across your room and sleep close to the floor, (where it’s cooler in summer, or closer to the ceiling where it’s warmer in winter.) Find the room with the best sleeping temperature and move your bedroom there.

Different mattress and sheet surfaces will feel cooler or warmer, so experiment to find what works best for you. Different types and extent of clothing obviously matters, but have you actually experimented to see how what you wear (or don’t wear) affects your perception of temperature?

Comfort

In general, splurge on things for your bed: Mattress, sheets, covers, comforters, pillows etc. Buy the most comfortable mattress, and the sheets you love to slide into. Then go another step and buy two sets of the sheets you love. (When you change the sheets you can strip and immediately remake the bed with clean linen.)

Improve the psychological comfort of your bed. Make changes, and build habits, which make the bed a comfortable, inherently relaxing, space. Room details such as color (hint: darker hues and blues are relaxing), lighting and general “busyness” of the room all have a subtle effect on your mood.

Slightly less obvious is to make your bed every morning. It doesn’t have to be fancy with specific folds or tucks, just make it up to whatever your definition of “made up” is. Later, each time you see the bed it will look inviting all made up, and you’ll look forward to peeling it open and sliding in.

Because it is a large, clear, open, space it will generally attract — but especially if you make it up each morning — random items throughout the day. Pay attention to what ends up on the bed and find proper homes, or invent systems, to keep those things off the bed. (For example: Clothes go ‘here’, worn-but-still-wearable items go ‘there’, pets are excluded by closing the door, put a chair in the room for sitting when dressing, etc.)

Avoidance

I’ve read various things about avoiding blue light in general, computer screens, TV, etc. But I’ve found that simply avoiding whatever it is that “winds me up” is sufficient to not sabotage my sleep. So, while I will look at my computer or phone near bed time, I don’t go to web sites or apps where I know I’ll get sucked down the rabbit hole. Instead, I’ll read through news feeds, e-books, or review my personal productivity systems and to-do lists. A lot of being able to readily fall asleep is related to my thinking-brain being relaxed. If there are things on my mind then I find I’ll be stuck laying awake in bed.

Eating

As with everything here, the key is to figure out what foods, and what eating times, affect your sleep.

I try to avoid eating within a few hours of going to sleep.
(In another part of this series, I’ll talk about intermittent fasting.) I find that I can sleep very well after a meal, particularly if I’ve had a couple hours for my digestion to get started.

What I’ve eaten also has a huge impact on my ability to fall asleep, and on my sleep quality. Too many sweets, or almost any amount of alcohol, to close to bed time will affect my sleep; I can fall asleep, but after an hour or so I find I’m wide awake. Same thing if I drink too much coffee. I’m pretty sure the stimulants (sugar, caffeine) and depressants (alcohol) affect my ability to reach the deeper sleep levels, and so I wake up instead of sleeping deeply. There’s a tremendous amount of information available about food and diet. Related to sleep, it’s worth looking into issues of digestion and experimenting to see what works for you.

Magnesium

There is solid evidence that Magnesium deficiency can cause sleep problems (restless legs, muscle cramps and more.) It is also a well-known relaxant. So that’s doubly suggestive that Magnesium (reading, experimentation, supplementation) could be very useful in improving your sleep. See Magnesium and Sleep.

Technology

There’s a lot you can do in terms of tracking sleep with things like Fitbits and Beddits. (Tracking is part of the “quantified self” movement.) Here again, the goal would be to measure something (sleep duration, quality, presence of sleep apnea, number of sleep cycles, etc.,) correlate that with how you feel and how it affects your life, and then make adjustments to your sleeping environment, habits and life in general. I did a small amount of tracking with a Fitbit. (I didn’t like the blindingly-bright green lights it uses for the pulse sensor. That’s how dark it is where I sleep.) But, for the period of time when I was tracking my sleep quality, it certainly helped focus my attention and efforts on improving my sleep.

Mental Activity

If I have too much on my mind, I sometimes have trouble falling asleep. When I first started working on my sleep I wasn’t yet journaling. Years later I started journaling and I found that emptying my brain in the evening was a wonderfully relaxing way to prepare for bed. Over the years, it became clear that as my time ran out each day, sitting down consistently to journal was difficult. So these days, I don’t regularly journal in the evening. (Instead, I write as part of my morning routine.) But sometimes I will journal to empty my thoughts if I feel that I’ve too much on my mind to readily fall asleep.

Room Usage

Don’t do anything other than sleep in your bed. Don’t read in bed, watch tv, or use digital devices. Whatever you do regularly, that is what you’re training yourself to do in that space. Have a “going to bed” routine, and turn out the lights.

Napping

For me, I can take a half hour blink-nap in the afternoon without it missing up my sleep. (A blink-nap is where I’m thinking, “I feel like I need a nap,” I lay down, blink, and a half hour has elapsed.)

Next up…

A few things I have not tried…

Andrew Foster: Global journey, losing everything, and finding purpose

What does it take to transform personal struggles and passions into a thriving community that fosters movement, connection, and belonging?

Andrew Foster shares his fascinating journey from his home-schooled beginnings in Ohio, Arabic studies, and living in Jordan, (including meeting and training with Danny Ilabaca in Cairo) to facing the dark challenge of losing everything- including his purpose in life. Starting renewed from his lowest point, on a mountaintop in Colorado, he describes finding new purpose and direction, bringing him full circle to his home town in Ohio.

We come from dust, and we return to dust. We don’t have anything except what we’re given.

~ Andrew Foster (16:09)

Andrew Foster recounts his life journey, beginning with a childhood filled with classical music, philosophy, and a homeschooling environment that prioritized learning over grades. He describes his forays into sports like swimming and soccer, where he embraced the challenges of being an underdog. His passion for movement led him to Parkour, despite initial parental opposition, and to formative experiences abroad in the Middle East, where he studied Arabic and connected with Parkour communities.

A pivotal moment came when Andrew faced personal and professional loss, culminating in a cathartic experience atop a Colorado mountain. This epiphany shifted his perspective on life, motivating him to embrace gratitude, faith, and a commitment to community. Returning to Ohio, he founded Akron Movement Family, a Parkour gym centered on movement, love, and family, with the goal of creating a supportive, inclusive space for individuals to thrive physically and emotionally.

Finn Berggren: Gerlev Idrætshøjskole, sportification, and the Olympics

What are the transformative possibilities of integrating Parkour into educational frameworks, and how can its values be preserved amidst sportification pressures?

Finn Berggren shares his thoughts on Parkour, explaining why he brought Parkour to Gerlev Idrætshøjskole in Denmark to replace the traditional gymnastics curriculum. We also discuss the “sportification” of Parkour and the Olympics, and he shares his story of the pivotal moment which solidified his decision to bring Parkour to Gerlev.

We built the first Parkour park in the world because it was a park designed to teach for pedagogical reasons and not just for doing, but also to learn how to do it and, at the same time, understand the philosophy behind Parkour.

~ Finn Berggren (7:00)

Finn Berggren shares his experiences as the principal of Gerlev Sports Academy, where he has transformed the institution’s approach to movement education by integrating Parkour. He recounts discovering Parkour through a television program and how its unstructured, innovative nature captivated him. His vision led to the creation of the world’s first pedagogical Parkour park, designed to teach movement and philosophy rather than competitive techniques. Finn discusses Gerlev’s evolution from a gymnastics-focused academy to a hub for diverse movement practices, including Parkour and street dance, emphasizing personal development and inclusivity.

Finn also reflects on the broader implications of sportification, warning against its potential to restrict the freedom and creativity inherent in Parkour. He advocates for preserving its unstructured, exploratory spirit and suggests using networks rather than rigid organizations to maintain its authenticity. Finn shares a personal story of witnessing children’s spontaneous engagement with movement, underscoring the importance of fun, challenge, and reflection in promoting physical activity and holistic development.

Max Henry: Parkour Roadmap, infrastructure, and growth

What is the unique role of Parkour in fostering mindfulness, community, and personal growth?

Max Henry shares his introduction and journey into parkour, and how he’s gotten to where he is. He unpacks his book, the Parkour Roadmap, explaining what it is, and why he wrote it, before delving into his work on the Water Project with Know Obstacles. Max discusses his thoughts on the infrastructure of parkour, the changes parkour could undergo as it evolves, and the responsibility he feels to preserve the heart of parkour as it grows.

The story that you tell people is the story that they’ll believe, and that’s the story that you become.

~ Max Henry (18:20)

This conversation explores Max Henry’s journey in Parkour, detailing his early fascination with movement and the philosophy underpinning the discipline. Max shares how his diverse background in sports and music influenced his approach, and he reflects on the role of mindfulness in overcoming physical and mental barriers in training. The conversation highlights his dedication to the global Parkour community, as seen through his coaching work and involvement in projects like the Copper Water initiative in Africa.

The discussion goes into the maturation of Parkour as a sport, addressing its increasing accessibility, media portrayal, and potential future directions. Key themes include preserving the spirit of Parkour while embracing its growth, the challenges faced by professional athletes in the field, and the importance of community-driven efforts to ensure its sustainable development.

§10 – Undershoot Overshoot →

Published May 26, 2017  ·  All posts on May 26  ·  ,

This entry is part 22 of 37 in the series Study inspired by Pakour & Art du Déplacement by V. Thibault

Thibault uses the phrase, “mindful resource management,” which resonates with one of my frequent avenues of thought.

Today, I can easily take one thousand steps without risk of injury, and I could take one thousand steps every day without developing chronic injury. In fact, such regular walking is improving my general health. (Although I expect that at some point it will simply be maintaining my general health.) Clearly then, these resources are well-spent on walking. But what about some specific running precision? How many can I do well? How many can I do before I’m tearing down my tomorrow-self more than will benefit my next-week-self? What about some other challenge? Where is the tipping point where I go from, “sustainable growth,” to “acute or chronic injury?”

To answer my own questions I must apply mindful resource management and calibrate my efforts. These concepts are important, explicit and obvious in Parkour. With movement, success or failure is usually obvious, and I can continuously calibrate my movements as I over-/undershoot. Initially I “throw myself at it” with flat trajectories and smash-crash-bang landings, but eventually I learn to “float in” with higher trajectories, more power, and more control.

In a larger sense, this applies not only to my Parkour efforts, but to my everyday life. Much of what I do could be calibrated: Food consumption; Listening skills; Speaking skills; Time spent interacting with others versus time spent alone; Self-reflective thought versus philosophical discussion; Mindful meditation and recovery work versus high-intensity physical training.

In the largest sense, this calibration tracks a life-span.
Beginning with the frenetic activity of youth, actively trying to carve my life through the universe: Overshooting. Then comes the inevitable, timorous, mid-life reversal to a hyper-aware, hyper-reflective approach: Undershooting. And then finally — hopefully! — a calibrated, broad, world-view.

A balance of give and take.
Power and control.
Life and death.
Yin and yang.

How “tuned in” is your nervous system? →

Published May 13, 2017  ·  All posts on May 13  ·  ,

With the foot as the only contact point between the body and the ground – much of this “noise” enters our nervous system through the feet. If this foot “noise” is tuned out or unable to be sensed by the nervous system inaccurate movement patterns and delayed time to stabilization (i.e. injury) is the result.
