Building & Maintaining Mobility!
This is Juliet Starrett. She’s a CrossFit co-founder, and two-time white-water rafting world champion. Oh, and she won those after battling thyroid cancer. She’s now 50 years old, and still going strong, having put aside her career as a lawyer to focus on fitness. Specifically, mobility training.
The Ready State
Together with her husband Kelly, Starrett co-founded The Ready State, of which she’s CEO.
It used to be called “Mobility WOD” (the “WOD” stands for “workout of the day”) but they changed their name as other companies took up the use of the word “mobility”, something the fitness world hadn’t previously focussed on much, and “WOD”, which was also hardly copyrightable.
True to its origins, The Ready State continues to offer many resources for building and maintaining mobility.
Why the focus on mobility?
When was the last time you had to bench-press anything larger than a small child? Or squat more than your partner’s bodyweight? Or do a “farmer’s walk” with anything heavier than your groceries?
For most of us, unless our lifestyles are quite extreme, we don’t need ridiculous strength (fun as that may be).
You know what makes a huge difference to our quality of life though? Mobility.
Have you ever felt that moment of panic when you reach for something on a high shelf and your shoulder or back twinges (been there!)? Or worse, you actually hurt yourself and the next thing you know, you need help putting your socks on (been there, too!)?
And we say to ourselves “I’m not going to let that happen to me again”
But how? How do we keep our mobility strong?
First, know your weaknesses
Starrett is a big fan of mobility tests to pinpoint areas that need more work.
Most of her resources for this aren’t free, and we’re drawing heavily from her book here, so for your convenience, we’ll link to some third party sources for this:

Next, eliminate those weaknesses
Do mobility exercises in any weak areas, until they’re not weak:

Could Just Two Hours Sleep Per Day Be Enough?

Polyphasic Sleep… Super-Schedule Or An Idea Best Put To Rest?
What is it?
Let’s start by defining some terms:
- Monophasic sleep—sleeping in one “chunk” per day. For example, a good night’s “normal” sleep.
- Biphasic sleep—sleeping in two “chunks” per day. Typically, a shorter night’s sleep, with a nap usually around the middle of the day / early afternoon.
- Polyphasic sleep—sleeping in two or more “chunks per day”. Some people do this in order to have more hours awake per day, to do things. The idea is that sleeping this way is more efficient, and one can get enough rest in less time. The most popular schedules used are:
- The Überman schedule—six evenly-spaced 20-minute naps, one every four hours, throughout the 24-hour day. The name is a semi-anglicized version of the German word Übermensch, “Superman”.
- The Everyman schedule—a less extreme schedule, that has a three-hours “long sleep” during the night, and three evenly-spaced 20-minute naps during the day, for a total of 4 hours sleep.
There are other schedules, but we’ll focus on the most popular ones here.
Want to learn about the others? Visit: Polyphasic.Net (a website by and for polyphasic sleep enthusiasts)
Some people have pointed to evidence that suggests humans are naturally polyphasic sleepers, and that it is only modern lifestyles that have forced us to be (mostly) monophasic.
There is at least some evidence to suggest that when environmental light/dark conditions are changed (because of extreme seasonal variation at the poles, or, as in this case, because of artificial changes as part of a sleep science experiment), we adjust our sleeping patterns accordingly.
The counterpoint, of course, is that perhaps when at the mercy of long days/nights at the poles, or no air-conditioning to deal with the heat of the day in the tropics, that perhaps we were forced to be polyphasic, and now, with modern technology and greater control, we are free to be monophasic.
Either way, there are plenty of people who take up the practice of polyphasic sleep.
Ok, But… Why?
The main motivation for trying polyphasic sleep is simply to have more hours in the day! It’s exciting, the prospect of having 22 hours per day to be so productive and still have time over for leisure.
A secondary motivation for trying polyphasic sleep is that when the brain is sleep-deprived, it will prioritize REM sleep. Here’s where the Überman schedule becomes perhaps most interesting:
The six evenly-spaced naps of the Überman schedule are each 20 minutes long. This corresponds to the approximate length of a normal REM cycle.
Consequently, when your head hits the pillow, you’ll immediately begin dreaming, and at the end of your dream, the alarm will go off.
Waking up at the end of a dream, when one hasn’t yet entered a non-REM phase of sleep, will make you more likely to remember it. Similarly, going straight into REM sleep will make you more likely to be aware of it, thus, lucid dreaming.
Read: Sleep fragmentation and lucid dreaming (actually a very interesting and informative lucid dreaming study even if you don’t want to take up polyphasic sleep)
Six 20-minute lucid-dreaming sessions per day?! While awake for the other 22 hours?! That’s… 24 hours per day of wakefulness to use as you please! What sorcery is this?
Hence, it has quite an understandable appeal.
Next Question: Does it work?
Can we get by without the other (non-REM) kinds of sleep?
According to Überman cycle enthusiasts: Yes! The body and brain will adapt.
According to sleep scientists: No! The non-REM slow-wave phases of sleep are essential
Read: Adverse impact of polyphasic sleep patterns in humans—Report of the National Sleep Foundation sleep timing and variability consensus panel
(if you want to know just how bad it is… the top-listed “similar article” is entitled “Suicidal Ideation”)
But what about, for example, the Everman schedule? Three hours at night is enough for some non-REM sleep, right?
It is, and so it’s not as quickly deleterious to the health as the Überman schedule. But, unless you are blessed with rare genes that allow you to operate comfortably on 4 hours per day (you’ll know already if that describes you, without having to run any experiment), it’s still bad.
Adults typically need 7–9 hours of sleep per night, and if you don’t get it, you’ll accumulate a sleep debt. And, importantly:
When you accumulate sleep debt, you are borrowing time at a very high rate of interest!
And, at risk of laboring the metaphor, but this is important too:
Not only will you have to pay it back soon (with interest), you will be hounded by the debt collection agents—decreased cognitive ability and decreased physical ability—until you pay up.
In summary:
- Polyphasic sleep is really very tempting
- It will give you more hours per day (for a while)
- It will give the promised lucid dreaming benefits (which is great until you start micronapping between naps, this is effectively a mini psychotic break from reality lasting split seconds each—can be deadly if behind the wheel of a car, for instance!)
- It is unequivocally bad for the health and we do not recommend it
Bottom line:
Some of the claimed benefits are real, but are incredibly short-term, unsustainable, and come at a cost that’s far too high. We get why it’s tempting, but ultimately, it’s self-sabotage.
(Sadly! We really wanted it to work, too…)

No, your aches and pains don’t get worse in the cold. So why do we think they do?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s cold and wet outside. As you get out of bed, you can feel it in your bones. Your right knee is flaring up again. That’ll make it harder for you to walk the dog or go to the gym. You think it must be because of the weather.
It’s a common idea, but a myth.
When we looked at the evidence, we found no direct link between most common aches and pains and the weather. In the first study of its kind, we found no direct link between the temperature or humidity with most joint or muscle aches and pains.
So why are so many of us convinced the weather’s to blame? Here’s what we think is really going on.
fongbeerredhot/Shutterstock Weather can be linked to your health
The weather is often associated with the risk of new and ongoing health conditions. For example, cold temperatures may worsen asthma symptoms. Hot temperatures increase the risk of heart problems, such as arrhythmia (irregular heartbeat), cardiac arrest and coronary heart disease.
Many people are also convinced the weather is linked to their aches and pains. For example, two in every three people with knee, hip or hand osteoarthritis say cold temperatures trigger their symptoms.
Musculoskeletal conditions affect more than seven million Australians. So we set out to find out whether weather is really the culprit behind winter flare-ups.
What we did
Very few studies have been specifically and appropriately designed to look for any direct link between weather changes and joint or muscle pain. And ours is the first to evaluate data from these particular studies.
We looked at data from more than 15,000 people from around the world. Together, these people reported more than 28,000 episodes of pain, mostly back pain, knee or hip osteoarthritis. People with rheumatoid arthritis and gout were also included.
We then compared the frequency of those pain reports between different types of weather: hot or cold, humid or dry, rainy, windy, as well as some combinations (for example, hot and humid versus cold and dry).
Bad back on a cold day? We wanted to know if the weather was really to blame. Pearl PhotoPix/Shutterstock What we found
We found changes in air temperature, humidity, air pressure and rainfall do not increase the risk of knee, hip or lower back pain symptoms and are not associated with people seeking care for a new episode of arthritis.
The results of this study suggest we do not experience joint or muscle pain flare-ups as a result of changes in the weather, and a cold day will not increase our risk of having knee or back pain.
In order words, there is no direct link between the weather and back, knee or hip pain, nor will it give you arthritis.
It is important to note, though, that very cold air temperatures (under 10°C) were rarely studied so we cannot make conclusions about worsening symptoms in more extreme changes in the weather.
The only exception to our findings was for gout, an inflammatory type of arthritis that can come and go. Here, pain increased in warmer, dry conditions.
Gout has a very different underlying biological mechanism to back pain or knee and hip osteoarthritis, which may explain our results. The combination of warm and dry weather may lead to increased dehydration and consequently increased concentration of uric acid in the blood, and deposition of uric acid crystals in the joint in people with gout, resulting in a flare-up.
Why do people blame the weather?
The weather can influence other factors and behaviours that consequently shape how we perceive and manage pain.
For example, some people may change their physical activity routine during winter, choosing the couch over the gym. And we know prolonged sitting, for instance, is directly linked to worse back pain. Others may change their sleep routine or sleep less well when it is either too cold or too warm. Once again, a bad night’s sleep can trigger your back and knee pain.
Likewise, changes in mood, often experienced in cold weather, trigger increases in both back and knee pain.
So these changes in behaviour over winter may contribute to more aches and pains, and not the weather itself.
Believing our pain will feel worse in winter (even if this is not the case) may also make us feel worse in winter. This is known as the nocebo effect.
When it’s cold outside, we may be less active. Anna Nass/Shutterstock What to do about winter aches and pains?
It’s best to focus on risk factors for pain you can control and modify, rather than ones you can’t (such as the weather).
You can:
- become more physically active. This winter, and throughout the year, aim to walk more, or talk to your health-care provider about gentle exercises you can safely do at home, with a physiotherapist, personal trainer or at the pool
- lose weight if obese or overweight, as this is linked to lower levels of joint pain and better physical function
- keep your body warm in winter if you feel some muscle tension in uncomfortably cold conditions. Also ensure your bedroom is nice and warm as we tend to sleep less well in cold rooms
- maintain a healthy diet and avoid smoking or drinking high levels of alcohol. These are among key lifestyle recommendations to better manage many types of arthritis and musculoskeletal conditions. For people with back pain, for example, a healthy lifestyle is linked with higher levels of physical function.

The Compass of Pleasure – by Dr. David Linden
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
There are a lot of books about addiction, so what sets this one apart?
Mostly, it’s that this one maintains that addiction is neither good nor bad per se—just, some behaviors and circumstances are. Behaviors and circumstances caused, directly or indirectly, by addiction.
But, Dr. Linden argues, not every addiction has to be so. Especially behavioral addictions; the rush of dopamine one gets from a good session at the gym or learning a new language, that’s not a bad thing, even if they can fundamentally be addictions too.
Similarly, we wouldn’t be here as a species without some things that rely on some of the same biochemistry as addictions; orgasms and eating food, for example. Yet, those very same urges can also inconvenience us, and in the case of foods and other substances, can harm our health.
In this book, the case is made for shifting our addictive tendencies to healthier addictions, and enough information is given to help us do so.
Bottom line: if you’d like to understand what is going on when you get waylaid by some temptation, and how to be tempted to better things, this book can give the understanding to do just that.

Fix Chronic Fatigue & Regain Your Energy, By Science
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Chronic fatigue is on the rise. A lot of it appears to be Long COVID-related, but whether that’s the case for you or not, one thing that will make a big difference to your energy levels is something that French biochemist Jessie Inchauspé is here to explain:
Mitochondrial management
Inchauspé explains it in terms of a steam train; to keep running, it must have coal burning in its furnace. However, if more coal is delivered to the engine room faster than it can be put in the furnace and burned, and the coal just keeps on coming, the worker there will soon be overwhelmed trying to find places to put it all; the engine room will be full of coal, and the furnace will sputter and go out because the worker can’t even reach it on account of being buried in coal.
So it is with our glucose metabolism also. If we get spikes of glucose faster than our body can deal with them, it will overload the body’s ability to process that energy at all. Just like the steam train worker, our body will try! It’ll stuff that extra glucose wherever it can (storing as glycogen in the liver is a readily available option that’s easy to do and/but also gives you non-alcoholic fatty liver disease and isn’t quickly broken down into useable energy), and meanwhile, your actual mitochondria aren’t getting what they need (which is: a reliable, but gentle, influx of glucose).
You can imagine that the situation we described in the steam train isn’t good for the engine’s longevity, and the corresponding situation in the human body isn’t good for our mitochondria either (or our pancreas, or our liver, or… the list goes on). Indeed, damaged mitochondria affect exercise capacity and stress resilience—as well as being a long-term driver of cancer.
The remedy, of course, is blood sugar management. Specifically, avoiding glucose spikes. She has a list of 10 ways to do this (small changes to how we eat; what things to eat with what, in which order, etc) that make a huge measurable difference. For your convenience, we’ve linked those ten ways below; first though, if you’d like to hear it from Inchauspé directly (her style is very pleasant), enjoy:

Most People Try The Wrong Way To Unshrimp Their Posture (Here’s How To Do It Better)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Many people try to correct posture by pulling the shoulders back and tucking in the chin, but that doesn’t work. Happily, there is a way that does! Kinesiologist Kyle Waugh demonstrates:
Defying gravity
The trick is simple, and is about how maintaining good posture needs to be unconscious and natural, not forced. After all, who is maintaining singular focus for 16 waking hours a day?
Instead, pay attention to how the body relates to gravity without excessive muscle tension, aligning the (oft-forgotten!) hips, and maintaining balance. The importance of hip position is really not to be underestimated, since in many ways the hips are a central axis of the body just as the spine is, and the spine itself sits in the hips.
A lot of what holds the body in poor posture tends to be localized muscle tensions, so address those with stretches and relaxation exercises.

Stolen Focus – by Johann Hari
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Having trouble concentrating for long periods? It’s not just a matter of getting older…
Johann Hari outlines twelve key ways in which our attention has not merely “wandered”, so much as it has been outright stolen.
By whom? For what purpose? Obvious culprits include social media and outrage-stoking news outlets, but the problem, as Hari illustrates, goes much deeper than that.
He talks about how we cannot truly multi-task, and can only switch beween tasks, at a cost. And yet, the modern world is not at all friendly to single-tasking!
Writer’s note: as I write this, I have active two screens, containing four windows, one of which has three tabs open. I am not multitasking; all those things pertain to the work I am doing right now. If I closed them between use, it’d only cost me more time and attention opening and closing them all the time. And yet, my working conditions are considered practically “hyperfocused” in this century!
- We learn about how the working world has changed, and the rise of physical and mental exhaustion that has come with it.
- We learn about the collapse of sustained reading, that started well before the modern Internet.
- We learn about factors such as dietary shifts that sap our energy too.
…and more. Twelve key things, remember.
But, it’s not all doom and gloom. There are things we can do to fight back. Some are personal changes; others are societal changes to push for.
The last part of the book is given over to, essentially, a manifesto (and how-to guide) for reclaiming our attention and thinking deeply again.
Bottom line: if you struggle with maintaining attention; this is a book for you. You might want to put your phone in a drawer while you read it, though
