Thinking of using an activity tracker to achieve your exercise goals? Here’s where it can help – and where it probably won’t

It’s that time of year when many people are getting started on their resolutions for the year ahead. Doing more physical activity is a popular and worthwhile goal.
If you’re hoping to be more active in 2024, perhaps you’ve invested in an activity tracker, or you’re considering buying one.
But what are the benefits of activity trackers? And will a basic tracker do the trick, or do you need a fancy one with lots of features? Let’s take a look.
Why use an activity tracker?
One of the most powerful predictors for being active is whether or not you are monitoring how active you are.
Most people have a vague idea of how active they are, but this is inaccurate a lot of the time. Once people consciously start to keep track of how much activity they do, they often realise it’s less than what they thought, and this motivates them to be more active.
You can self-monitor without an activity tracker (just by writing down what you do), but this method is hard to keep up in the long run and it’s also a lot less accurate compared to devices that track your every move 24/7.
By tracking steps or “activity minutes” you can ascertain whether or not you are meeting the physical activity guidelines (150 minutes of moderate to vigorous physical activity per week).
It also allows you to track how you’re progressing with any personal activity goals, and view your progress over time. All this would be difficult without an activity tracker.
Research has shown the most popular brands of activity trackers are generally reliable when it comes to tracking basic measures such as steps and activity minutes.
But wait, there’s more
Many activity trackers on the market nowadays track a range of other measures which their manufacturers promote as important in monitoring health and fitness. But is this really the case? Let’s look at some of these.
Resting heart rate
This is your heart rate at rest, which is normally somewhere between 60 and 100 beats per minute. Your resting heart rate will gradually go down as you become fitter, especially if you’re doing a lot of high-intensity exercise. Your risk of dying of any cause (all-cause mortality) is much lower when you have a low resting heart rate.
So, it is useful to keep an eye on your resting heart rate. Activity trackers are pretty good at tracking it, but you can also easily measure your heart rate by monitoring your pulse and using a stopwatch.
Heart rate during exercise
Activity trackers will also measure your heart rate when you’re active. To improve fitness efficiently, professional athletes focus on having their heart rate in certain “zones” when they’re exercising – so knowing their heart rate during exercise is important.
But if you just want to be more active and healthier, without a specific training goal in mind, you can exercise at a level that feels good to you and not worry about your heart rate during activity. The most important thing is that you’re being active.
Also, a dedicated heart rate monitor with a strap around your chest will do a much better job at measuring your actual heart rate compared to an activity tracker worn around your wrist.
Maximal heart rate
This is the hardest your heart could beat when you’re active, not something you could sustain very long. Your maximal heart rate is not influenced by how much exercise you do, or your fitness level.
Most activity trackers don’t measure it accurately anyway, so you might as well forget about this one.
VO₂max
Your muscles need oxygen to work. The more oxygen your body can process, the harder you can work, and therefore the fitter you are.
VO₂max is the volume (V) of oxygen (O₂) we could breathe maximally (max) over a one minute interval, expressed as millilitres of oxygen per kilogram of body weight per minute (ml/kg/min). Inactive women and men would have a VO₂max lower than 30 and 40 ml/kg/min, respectively. A reasonably good VO₂max would be mid thirties and higher for women and mid forties and higher for men.
VO₂max is another measure of fitness that correlates well with all-cause mortality: the higher it is, the lower your risk of dying.
For athletes, VO₂max is usually measured in a lab on a treadmill while wearing a mask that measures oxygen consumption. Activity trackers instead look at your running speed (using a GPS chip) and your heart rate and compare these measures to values from other people.
If you can run fast with a low heart rate your tracker will assume you are relatively fit, resulting in a higher VO₂max. These estimates are not very accurate as they are based on lots of assumptions. However, the error of the measurement is reasonably consistent. This means if your VO₂max is gradually increasing, you are likely to be getting fitter.
So what’s the take-home message? Focus on how many steps you take every day or the number of activity minutes you achieve. Even a basic activity tracker will measure these factors relatively accurately. There is no real need to track other measures and pay more for an activity tracker that records them, unless you are getting really serious about exercise.

Savoy Cabbage vs Pak Choi – Which is Healthier?
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.
Our Verdict
When comparing savoy cabbage to pak choi, we picked the savoy.
Why?
Looking at the macros first, the savoy has a little more protein, just under 3x the carbs, and just over 3x the fiber. A modest yet respectable win for savoy.
In terms of vitamins, savoy has more of vitamins B1, B5, B9, E, K, and choline, while pak choi has more of vitamins A, B2, B3, and C. Thus, a 6:4 win for savoy.
When it comes to minerals, savoy has more copper, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while pak choi has more calcium, iron, and potassium. So this time, a 7:3 win for savoy.
On the other hand, pak choi scores higher on the polyphenols side, especially in the categories of kaempferol and quercetin.
Still, adding up the sections, we conclude this one’s an overall win for savoy cabbage. Of course, enjoy either or both, though!

Cleaning Up Your Mental Mess – by Dr. Caroline Leaf
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.
First of all, what mental mess is this? Well, that depends on you, but common items include:
- Anxiety
- Depression
- Stress
- Trauma
Dr. Caroline Leaf also includes the more nebulous item “toxic thoughts”, but this is mostly a catch-all term.
Given that it says “5 simple scientifically proven steps”, it would be fair if you are wondering:
“Is this going to be just basic CBT stuff?”
And… First, let’s not knock basic CBT stuff. It’s not a panacea, but it’s a great tool for a lot of things. However… Also, no, this book is not about just basic CBT stuff.
In fact, this book’s methods are presented in such a novel way that this reviewer was taken aback by how unlike it was to anything she’d read before.
And, it’s not that the components themselves are new—it’s just that they’re put together differently, in a much more organized comprehensive and systematic way, so that a lot less stuff falls through the cracks (a common problem with standalone psychological tools and techniques).
Bottom line: if you buy one mental health self-help book this year, we recommend that it be this one

The Keys to Good Mental Wellbeing
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.
The Nine Keys To Good Mental Wellbeing
Today’s main feature is a bit “pop psychology”, but it has its underpinnings in actual psychology, and is especially useful if approached from that angle.
What it’s most popularly enjoyed as:
- A personality-typing system.
- People love little quizzes and identifiers and such.
What it’s actually really useful as:
- A tool for understanding why people (including ourselves) are the way we are
- A foundational knowledge for living better ourselves, and helping others too
This stems from the fairly simple principle, uncontroversial in psychology:
- We have needs, desires, and aversions
- We act in a way that tries to get our needs met and avoid suffering
- Thus: Need/Fear → Motivation → Action
The Enneagram
The Enneagram (ἐννέα = “nine” in Ancient Greek) system posits that we each have one fundamental need/fear (from a list of nine) that’s strongest for us. A deep-seated insecurity/longing, that we’ll go to almost any lengths to try to meet. Sometimes, in good ways, sometimes, bad.
The Nine Basic Fears/Insecurities, And Their Corresponding Needs/Desires:
- Fear of being a fundamentally bad, wrong person / Need to be good and correct
- Fear of being fundamentally unloveable / Need to be loved
- Fear of being fundamentally worthless / Need to be valued
- Fear of being like everyone else / Need to be different
- Fear of being useless / Need to be useful
- Fear of being outcast / Need to have a set place in the group
- Fear of missing out / Need to experience things
- Fear of being hurt or controlled / Need to be in control
- Fear of conflict / Need to be at peace
Of course, most of us have most of these fears/needs to some extent, though usually one will stand out—especially if we aren’t managing it well. The less healthy our coping mechanisms, the more obvious it is how we’re trying to overcompensate in some fashion. For example:
- A person who fears being wrong and so becomes a perfectionist rules-abider to a fault
- A person who fears being unloveable, and so exaggerates problems to get pity, as the next best thing
- A person who fears being worthless, and so exaggerates their accomplishments in order to be admired and valued
- A person who fears being like everyone else, and so descends into a “nobody could ever possibly understand me” black hole of pathos.
- A person who fears being useless, so burns themself out trying to be an omnicompetent Leonardo da Vinci without ever actually taking the time to stop and smell the flowers as Leonardo did.
- A person who fears being outcast, so becomes clingy, passive-aggressive, and suspicious
- A person who fears missing out, so tries to experience all the things all the time, ruining their health with dizzying highs and crushing lows.
- A person who fears being hurt or controlled, so becomes aggressive and domineering
- A person who fears conflict, so shuts down at the slightest hint of it
If we have healthier coping mechanisms, these same nine people can look a lot different, but in much more subtle ways because we’re not trying to overcompensate so badly:
- A person who lives their life rationally by principles that can be adapted as they learn
- A person who loves and is loved, as perhaps the most notable part of their character
- A person who sets reasonable goals and accomplishes them, and seeks to uplift others
- A person who creates and innovates, enriching their own life and the lives of others
- A person who is simply very competent and knowledgeable, without overstretching
- A person who is dependable and loyal, and a reliable part of something bigger than themself
- A person who is fun to be around and loves trying new things, while also knowing how to relax
- A person who develops their leadership skills and is a tower of strength for others
- A person who knows how to make peace and does so—by themself, and with others
By being aware of our own fears/insecurities that may drive our motivations and thus underpin our behaviors, we can usually manage them in a much more mindful fashion. Same goes when it comes to managing interactions with other people, too:
- Letting the Type 3 know you value them, not their accomplishments or what they can do for you.
- Appreciating the Type 5’s (varied or specialist) skills and knowledge.
- Giving love to a Type 2 unprompted, but on your own terms, with your own boundaries.
- And so on for other types
Or for yourself…
- As a Type 8, remembering that you can let go sometimes and let someone else be in charge.
- As a Type 1, catching yourself holding yourself (or others) to impossible standards, and then easing up on that a little.
- As a Type 9, remembering to stand up for yourself and others, however gently, but firmly.
- And so on for other types
If you’re unsure what to focus on, ask yourself: what’s your worst nightmare or greatest daydream? Then work out what it is about that, that makes it feel so bad or good.
Then, approach things mindfully. Catch yourself in your unhealthy coping mechanisms, and find healthy ones instead.
What if I get my type wrong? Or I get someone else’s type wrong?
Obviously it’s better to get them right for maximum effect, but you can never go too far wrong anyway… because we all have all nine of those qualities in us, it’s just a matter of how strong a factor each is for us. So in the worst case scenario, you’ll make someone feel more secure about something that was only a very minor insecurity for them, for example.
Or in the case of your own type, you may mistakenly think you’re acing being the world’s healthiest Type 5, until you realize you’re actually a Type 3 who thought learning all those things would make you more worthy (spoiler: those things are great, but you’re worthy already). Again, not the end of the world! No matter what, you’re learning and growing, and that’s good.

Read: The Nine Enneagram Type Descriptions (Basic, but more detailed descriptions than the above)
Read: How The Enneagram System Works (More complex. Now we’re getting into the more arcane stuff we didn’t have time for today—wings and lines, triads, health levels, directions of integration and disintegration, and more)
Like learning from books? Here are our top two picks, depending on your learning style:
- The Wisdom of the Enneagram – Very comprehensive textbook and guide to improving your coping mechanism and growing as a person.
- The Enneagram Made Easy – it explains it with cartoons!
We’d love to offer a quick free test here, but all the tests we could find either require paid registration or are wildly inaccurate, so we’ll not waste your time.
However, we do also think that working it out for yourself is better, as it means you have a handle on what those ideas, fears, insecurities, desires, needs, really mean to you—that way you can actually use the information!
We’ll close by repeating our previous advice: If you’re unsure what to focus on, ask yourself: what’s your worst nightmare or greatest daydream? Then work out what it is about those scenarios that make them so bad or good. That’ll help you find your real fears/needs, such that you can work on them.
Good luck!

To Err Is Human; To Forgive, Healthy
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.
How To Forgive (And Why)
There’s an old saying that holding onto a grudge is like drinking poison and expecting the other person to die. If only it were so simple and easy as just choosing to let go!
But it’s not, is it?
When people have wronged us and/or wronged our loved ones, it’s hard to forgive, especially if they have not changed. For that matter, it can be hard to forgive ourselves for mistakes that we made, too.
Either way, “drinking that poison” can be close to literal, in terms of what harboring such anger and resentment can do for our cortisol levels.
So, what to do about it?
If you have a dialogue with the person, our previous article on communication may help a lot.
If you don’t, there are various other angles that can be taken:
The Unsent Letter
You can even send it, if you like, but it’s not the point here. The idea is to write to the person, expressing your grievances. But, (as per the above-linked article on communication) try to focus at least as much on your feelings as their actions. “When you did/said x, I felt y”, etc.
This is important for helping you process your feelings. If you send the letter, it’s also important for the other person to be able to understand your feelings.
Sometimes, we feel the things we do so strongly because we don’t have an outlet for them. Pouring out our emotions in such a fashion, on the other hand, means (to labor the metaphor) they’re no longer bottled up. Even just in and of itself, that can provide us a lot of relief.
And when we the negative emotions are no longer such high pressure, it can be easier to let go of them.
Mindfulness
Following on from the above idea, a good strategy can be simply sitting and feeling everything you need to feel, noticing it without judgement, like a curious observer.
Sometimes what we need is just to be heard, and that starts with hearing ourselves.
Compassion
There’s a Buddhist exercise that involves actively feeling compassion for three people: a loved one, a stranger, and an enemy. Many people report that it’s actually harder to feel compassion for a random stranger, than an enemy. Why? Because we don’t know them; we don’t know what’s good and bad about them in our estimation.
If you’re reading this because you want to be able to gain the peace of being able to forgive someone (even if that someone is yourself), then in at least some respect right now, that person is in the “enemy” category. So how do we unpack that?
To err is human. Everybody screws up sometimes. And also, everyone has a reason (or a complex of reasons) for acting the way they do. This does not mean that those reasons excuse the behavior, but it can explain it.
You don’t get angry at a storm for soaking you through. Even if you might not understand the physics of it in the way a meteorologist might, you understand that there were things that led to that, and you were just in the wrong place at the wrong time.
So why do we get angry at someone else for wronging us? Even if we might not understand the personal background of it in the way their psychologist or therapist might, we (hopefully) understand that there were things that caused them to be the way they were, and we were just in the wrong place at the wrong time.
And ourselves? We probably know, when we made a mistake, why we made it. Maybe we were afraid, insecure, reactive, forgetful, or too focused on some other thing. Whatever it was, we did our best at the time and, apparently, our best wasn’t as good as we’d like.
If we didn’t deserve forgiveness, we wouldn’t be critical of our past selves in the first place.
And, the science is very clear that it’s important for our health for other reasons besides cortisol management, too.
And as for others? They did the best they knew how. Maybe they were afraid, insecure, reactive, forgetful, or too focused on some other thing. Same story, different character.
Remembering that can be key to “accepting the apology we never received”.
Forgiving without forgetting
Developing the ability to forgive is a useful tool for our own mental health. It doesn’t mean we must or even should make ourselves a doormat.
“I forgive you” does not have to mean a clean slate; it means remembering that the thing happened, and just not holding on to the anger/resentment associated with it.
It may be water under the bridge now, but it might have been a devastatingly destructive wave at the time, and continuing to acknowledge truth that is sensible. Just, from a position of peace now, hopefully.

When And Why Do We Pick Up Our Phones?
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.
The School of Life’s Alain de Botton makes the argument that—if we pay attention, if we keep track—there’s an understory to why we pick up our phones:
It’s not about information
Yes, our phones (or rather, the apps therein) are designed to addict us, to draw us back, to keep us scrolling and never let us go. We indeed seek out information like our ancestors once sought out berries; searching, encouraged by a small discovery, looking for more. The neurochemistry is similar.
But when we look at the “when” of picking up our phones, de Botton says, it tells a different story:
We pick them up not to find out what’s going on with the world, but rather specifically to not find out what’s going with ourselves. We pick them up to white out some anxiety we don’t want to examine, a line of thought we don’t want to go down, memories we don’t want to consider, futures we do not want to have to worry about.
And of course, phones do have a great educational potential, are an immensely powerful tool for accessing knowledge of many kinds—if only we can remain truly conscious while using them, and not take them as the new “opiate of the masses”.
De Botton bids us, when next we pick up our phone. ask a brave question:
“If I weren’t allowed to consult my phone right now, what might I need to think about?”

Move over, COVID and Flu! We Have “Hybrid Viruses” To Contend With Now
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.
Move over, COVID and Flu! We have “hybrid viruses” to contend with now
COVID and influenza viruses can be serious, of course, so let’s be clear up front that we’re not being dismissive of those. But, most people are hearing a lot about them, whereas respiratory syncytial virus (RSV) has flown under a lot of radars.
Simply put, until recently it hasn’t been considered much of a threat except to the young, the old, or people with other respiratory illnesses. Only these days, the prevalence of “other respiratory illnesses” is a lot higher than it used to be!
It’s not just a comorbidity
It’s easy to think “well of course if you have more than one illness at once, especially similar ones, that’s going to suck” but it’s a bit more than that; it produces newer, more interesting, hybrid viruses. Here’s a research paper from last year’s “flu season”:
Coinfection by influenza A virus and respiratory syncytial virus produces hybrid virus particles
Best to be aware of this if you’re in the “older” age-range
It’s not just that the older we are, the more likely we are to get it. Critically, the older we are, the more likely we are to be hospitalized by it.
And..the older we are, the less likely we are to come back from hospital if hospitalized by it.
Some years back, the intensive care and mortality rates for people over the age of 65 were 8% and 7%, respectively:
Respiratory syncytial virus infection in elderly and high-risk adults
…but a new study this year has found the rates like to be 2.2x that, i.e. 15% intensive care rate and 18% mortality, respectively:
Want to know more?
Here are some hot-off-the-press news articles on the topic:
- Better awareness of RSV in older adults is needed to reduce hospitalizations
- Is there also a connection between RSV and asthma?
- Respiratory syncytial virus coinfections conspire to worsen disease
And as for what to do…
Same general advice as for COVID and Flu, just, ever-more important:
- Try to keep to well-ventilated places as much as possible
- Get any worrying symptoms checked out quickly
- Mask up when appropriate
- Get your shots as appropriate
