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.

Owning Your Weight – by Henri Marcoux
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.
A lot of diet books—which this isn’t—presuppose that the reader wants to lose weight, and varyingly encourage and shame the reader into trying to do so.
Dr. Henri Marcoux takes a completely different approach.
He starts by assuming we are—whether consciously or not—the weight we want to be, and looks at the various physical and psychological factors that influence us to such. Ranging from food poverty to eating our feelings to social factors and more, he bids us examine our relationship with food and eating—not just in the sense of mindful eating, but from multiple scientific angles too.
From this, Dr. Marcoux gives us questions and suggestions to ensure that our relationship with food and eating is what we want it to be, for us.
Much of the latter part of the book covers not just how to go about the requisite lifestyle changes… But also how to implement things in a way that sticks, and is a genuine pleasure to implement. If this sounds over-the-top, the truth is that it’s just because it honestly is a lower-stress way of living.
Bottom line: if you want to gain or lose weight, there’s a good chance this book will help you. If you want to be happier and healthier at the weight you are, there’s a good chance this book will help you with that, too.

The Comfort Zone – by Kristen Butler
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.
Are you sitting comfortably? Then we’ll begin. Funny, how being comfortable can be a good starting point, then we are advised “You have to get out of your comfort zone”.
And yet, when we think of our personal greatest moments in life, they were rarely uncomfortable moments. Why is that?
Kristen Butler wants us to resolve this paradox, with a reframe:
The comfort zone? That’s actually the “flow” zone.
Just as “slow and steady wins the race”, we can—like the proverbial tortoise—take our comfort with us as we go.
The discomfort zone? That’s the stress zone, the survival zone, the “putting out fires” zone. From the outside, it looks like we’re making a Herculean effort, and perhaps we are, but is it actually so much better than peaceful consistent productivity?
Butler writes in a way that will be relatable for many, and may be a welcome life-ring if you feel like you’ve been playing catch-up for a while.
Is she advocating for complacency, then? No, and she discusses this too. That “complacency zone” is really the “burnout zone” after being in the “survival zone” for too long.
She lays out for us, therefore, a guide for growing in comfort, expanding the comfort zone yes, but by securely pushing it from the inside, not by making a mad dash out and hoping it follows us.
Bottom line: if you’ve been (perhaps quietly) uncomfortable for a little too long for comfort, this book can reframe your approach to get you to a position of sustainable, stress-free growth.

Marrakesh Sorghum Salad
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.
As the name suggests, it’s a Maghreb dish today! Using sorghum, a naturally gluten-free whole grain with a stack of vitamins and minerals. This salad also comes with fruit and nuts (apricots and almonds; a heavenly combination for both taste and nutrients) as well as greens, herbs, and spices.
Note: to keep things simple today, we’ve listed ras el-hanout as one ingredient. If you’re unfamiliar, it’s a spice blend; you can probably buy a version locally, but you might as well know how to make it yourself—so here’s our recipe for that!
You will need
- 1½ cups sorghum, soaked overnight in water (if you can’t find it locally, you can order it online (here’s an example product on Amazon), or substitute quinoa) and if you have time, soaked overnight and then kept in a jar with just a little moisture for a few days until they begin to sprout—this will be best of all. But if you don’t have time, don’t worry about it; overnight soaking is sufficient already.
- 1 carrot, grated
- ½ cup chopped parsley
- 1 tbsp apple cider vinegar
- ½ tbsp chopped chives
- 2 tbsp ras el-hanout
- 3 cloves garlic, crushed
- 2 tbsp almond butter
- 1 tbsp lemon juice
- 1 tsp white miso paste
- ½ cup sliced almonds
- 4 fresh apricots, pitted and cut into wedges
- 1 cup mint leaves, chopped
- To serve: your choice of salad greens; we suggest chopped romaine lettuce and rocket
Method
(we suggest you read everything at least once before doing anything)
1) Cook the sorghum, which means boiling it for about 45 minutes, or 30 in a pressure cooker. If unsure, err on the side of cooking longer—even up to an hour will be totally fine. You have a lot of wiggle room, and will soon get used to how long it takes with your device/setup. Drain the cooked sorghum, and set it aside to cool. If you’re entertaining, we recommend doing this part the day before and keeping it in the fridge.
2) When it’s cool, add the carrot, the parsley, the chives, the vinegar, and 1 tbsp of the ras el-hanout. Toss gently but thoroughly to combine.
3) Make the dressing, which means putting ¼ cup water into a blender with the other 1 tbsp of the ras el-hanout, the garlic, the almond butter, the lemon juice, and the miso paste. Blend until smooth.
4) Assemble the salad, which means adding the dressing to sorghum-and-ingredients bowl, along with the almonds, apricots, and mint leaves. Toss gently, but sufficiently that everything is coated.
5) Serve on a bed of salad greens.
Enjoy!

The Burden of Getting Medical Care Can Exhaust Older Patients
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.
Susanne Gilliam, 67, was walking down her driveway to get the mail in January when she slipped and fell on a patch of black ice.
Pain shot through her left knee and ankle. After summoning her husband on her phone, with difficulty she made it back to the house.
And then began the run-around that so many people face when they interact with America’s uncoordinated health care system.
Gilliam’s orthopedic surgeon, who managed previous difficulties with her left knee, saw her that afternoon but told her “I don’t do ankles.”
He referred her to an ankle specialist who ordered a new set of X-rays and an MRI. For convenience’s sake, Gilliam asked to get the scans at a hospital near her home in Sudbury, Massachusetts. But the hospital didn’t have the doctor’s order when she called for an appointment. It came through only after several more calls.
Coordinating the care she needs to recover, including physical therapy, became a part-time job for Gilliam. (Therapists work on only one body part per session, so she has needed separate visits for her knee and for her ankle several times a week.)
“The burden of arranging everything I need — it’s huge,” Gilliam told me. “It leaves you with such a sense of mental and physical exhaustion.”
The toll the American health care system extracts is, in some respects, the price of extraordinary progress in medicine. But it’s also evidence of the poor fit between older adults’ capacities and the health care system’s demands.
“The good news is we know so much more and can do so much more for people with various conditions,” said Thomas H. Lee, chief medical officer at Press Ganey, a consulting firm that tracks patients’ experiences with health care. “The bad news is the system has gotten overwhelmingly complex.”
That complexity is compounded by the proliferation of guidelines for separate medical conditions, financial incentives that reward more medical care, and specialization among clinicians, said Ishani Ganguli, an associate professor of medicine at Harvard Medical School.
“It’s not uncommon for older patients to have three or more heart specialists who schedule regular appointments and tests,” she said. If someone has multiple medical problems — say, heart disease, diabetes, and glaucoma — interactions with the health care system multiply.
Ganguli is the author of a new study showing that Medicare patients spend about three weeks a year having medical tests, visiting doctors, undergoing treatments or medical procedures, seeking care in emergency rooms, or spending time in the hospital or rehabilitation facilities. (The data is from 2019, before the covid pandemic disrupted care patterns. If any services were received, that counted as a day of health care contact.)
That study found that slightly more than 1 in 10 seniors, including those recovering from or managing serious illnesses, spent a much larger portion of their lives getting care — at least 50 days a year.
“Some of this may be very beneficial and valuable for people, and some of it may be less essential,” Ganguli said. “We don’t talk enough about what we’re asking older adults to do and whether that’s realistic.”
Victor Montori, a professor of medicine at the Mayo Clinic in Rochester, Minnesota, has for many years raised an alarm about the “treatment burden” that patients experience. In addition to time spent receiving health care, this burden includes arranging appointments, finding transportation to medical visits, getting and taking medications, communicating with insurance companies, paying medical bills, monitoring health at home, and following recommendations such as dietary changes.
Four years ago — in a paper titled “2022 paper on reducing treatment burden.
Consider what Jean Hartnett, 53, of Omaha, Nebraska, and her eight siblings went through after their 88-year-old mother had a stroke in February 2021 while shopping at Walmart.
At the time, the older woman was looking after Hartnett’s father, who had kidney disease and needed help with daily activities such as showering and going to the bathroom.
During the year after the stroke, both of Hartnett’s parents — fiercely independent farmers who lived in Hubbard, Nebraska — suffered setbacks, and medical crises became common. When a physician changed her mom’s or dad’s plan of care, new medications, supplies, and medical equipment had to be procured, and new rounds of occupational, physical, and speech therapy arranged.
Neither parent could be left alone if the other needed medical attention.
“It wasn’t unusual for me to be bringing one parent home from the hospital or doctor’s visit and passing the ambulance or a family member on the highway taking the other one in,” Hartnett explained. “An incredible amount of coordination needed to happen.”
Hartnett moved in with her parents during the last six weeks of her father’s life, after doctors decided he was too weak to undertake dialysis. He passed away in March 2022. Her mother died months later in July.
So, what can older adults and family caregivers do to ease the burdens of health care?
To start, be candid with your doctor if you think a treatment plan isn’t feasible and explain why you feel that way, said Elizabeth Rogers, an assistant professor of internal medicine at the University of Minnesota Medical School.
“Be sure to discuss your health priorities and trade-offs: what you might gain and what you might lose by forgoing certain tests or treatments,” she said. Ask which interventions are most important in terms of keeping you healthy, and which might be expendable.
Doctors can adjust your treatment plan, discontinue medications that aren’t yielding significant benefits, and arrange virtual visits if you can manage the technological requirements. (Many older adults can’t.)
Ask if a social worker or a patient navigator can help you arrange multiple appointments and tests on the same day to minimize the burden of going to and from medical centers. These professionals can also help you connect with community resources, such as transportation services, that might be of help. (Most medical centers have staff of this kind, but physician practices do not.)
If you don’t understand how to do what your doctor wants you to do, ask questions: What will this involve on my part? How much time will this take? What kind of resources will I need to do this? And ask for written materials, such as self-management plans for asthma or diabetes, that can help you understand what’s expected.
“I would ask a clinician, ‘If I chose this treatment option, what does that mean not only for my cancer or heart disease, but also for the time I’ll spend getting care?’” said Ganguli of Harvard. “If they don’t have an answer, ask if they can come up with an estimate.”

Health Simplified – by Daniel Cottmeyer
A lot of books focus on the most marketable aspects of health, such as fat loss or muscle gain. Instead, Cottmeyer takes a “birds-eye-view” of health in all its aspects, and then boils it down to the most critical key parts.
Rather than giving a science-dense tome that nobody reads, or a light motivational piece that everyone reads but it amounts to “you can do it!”, here we get substance… but in a digestible form.
Which we at 10almonds love.
The book presents a simple action plan to:
- Improve your relationship with food/exercise
- Actually get better sleep
- Understand how nutrition really works
- Set up helpful habits that are workable and sustainable
- Bring these components together synergistically
Bottom line: if you’re going to buy only one health/fitness book, this is a fine contender.

Synergistic Brain-Training

Let The Games Begin (But It Matters What Kind)
Exercise is good for brain health; we’ve written about this before, for example:
How To Reduce Your Alzheimer’s Risk ← there are many advices here, but exercise, especially cardiovascular exercise in this case, is an important item on the list!
Today it’s Psychology Sunday though, and we’re going to talk about looking after brain health by means of brain-training, via games.
“Brain-training” gets a lot of hype and flak:
- Hype: do sudoku every day and soon you will have an IQ of 200 and still have a sharp wit at the age of 120
- Flak: brain-training is usually training only one kind of cognitive function, with limited transferability to the rest of life
The reality is somewhere between the two. Brain training really does improve not just outwardly measurable cognitive function, but also internally measurable improvements visible on brain scans, for example:
- Cognitive training modified age-related brain changes in older adults with subjective memory decline
- Functional brain changes associated with cognitive training in healthy older adults: A preliminary ALE meta-analysis
But what about the transferability?
Let us play
This is where game-based brain-training comes in. And, the more complex the game, the better the benefits, because there is more chance of applicability to life, e.g:
- Sudoku: very limited applicability
- Crosswords: language faculties
- Chess: spatial reasoning, critical path analysis, planning, memory, focus (also unlike the previous two, chess tends to be social for most people, and also involve a lot of reading, if one is keen)
- Computer games: wildly varied depending on the game. While an arcade-style “shoot-em-up” may do little for the brain, there is a lot of potential for a lot of much more relevant brain-training in other kinds of games: it could be planning, problem-solving, social dynamics, economics, things that mirror the day-to-day challenges of running a household, even, or a business.
- It’s not that the skills are useful, by the way. Playing “Stardew Valley” will not qualify you to run a real farm, nor will playing “Civilization” qualify you to run a country. But the brain functions used and trained? Those are important.
It becomes easily explicable, then, why these two research reviews with very similar titles got very different results:
- A Game a Day Keeps Cognitive Decline Away? A Systematic Review and Meta-Analysis of Commercially-Available Brain Training Programs in Healthy and Cognitively Impaired Older Adults
- Game-based brain training for improving cognitive function in community-dwelling older adults: A systematic review and meta-regression
The first review found that game-based brain-training had negligible actual use. The “games” they looked at? BrainGymmer, BrainHQ, CogMed, CogniFit, Dakim, Lumosity, and MyBrainTrainer. In other words, made-for-purpose brain-trainers, not actual computer games per se.
The second reviewfound that game-based training was very beneficial. The games they looked at? They didn’t name them, but based on the descriptions, they were actual multiplayer online turn-based computer games, not made-for-purpose brain-trainers.
To summarize the above in few words: multiplayer online turn-based computer games outperform made-for-purpose brain-trainers for cognitive improvement.
Bringing synergy
However, before you order that expensive gaming-chair for marathon gaming sessions (research suggests a tail-off in usefulness after about an hour of continuous gaming per session, by the way), be aware that cognitive training and (physical) exercise training combined, performed close in time to each other or simultaneously, perform better than the sum of either alone:
See also:
❝Simultaneous training was the most efficacious approach for cognition, followed by sequential combinations and cognitive training alone, and significantly better than physical exercise.
Our findings suggest that simultaneously and sequentially combined interventions are efficacious for promoting cognitive alongside physical health in older adults, and therefore should be preferred over implementation of single-domain training❞
