“Microbreaking” — also known as micro-exercise, or movement snacks — is a survival strategy for chair-bound office workers. It’s based on the idea that sitting too much is probably Bad For You, and that a little movement and stimulation sprinkled evenly throughout a day may be a partial antidote (as opposed to, say, an intense concentration of exercise in a morning workout, followed by several hours of growing roots into your chair). And hoo boy do modern humans sit a lot! In the United States, 8 hours per day for teens and 6 for adults, up an hour from 2008 to 2016.1
Microbreaks are small and relatively frequent exercise breaks from being stuck in one position at work. Almost any kind of exercise will do, but the more the better… as long as it still feels “easy,” brief. If your micro-exercise calls for a shower afterwards, it ain’t micro. If your micro-exercise needs a gym, you’re missing the point.
Ideally, for the extroverts, you do this with people, for the social benefits — which may be as much of an active ingredient as the exercise itself.
Ergonomics, schmergonomics: microbreaking is an upgrade to old-school ergonomic priorities that focus on ideal positioning and movement efficiency. No matter how perfectly arranged your computer workstation, it cannot protect you from the potential hazards of hours of stagnancy. The only truly ergonomic workstation is one that you regularly push away from! So that you can actually do something genuinely stimulating, such as a quick stair climb, some dynamic joint mobility drills.
The scientific case for microbreaking
Sedentariness and excessive sitting are not clear causes of back pain, contrary to popular assumption (an assumption I made myself for many years). The science over the last 20 years has been quite clear about this,2 with only shreds of contrary evidence that would encourage us. If sitting isn’t the problem, taking breaks from sitting probably isn’t good prevention or treatment for back pain — and if not for back pain, then probably no other common musculoskeletal pain either.
And yet! Modern data does show that
And the science is also clear that exercise and activity may be the best (or at least least disappointing) overall medicine for back pain.9 So while simply getting up out of your chair frequently might not matter much by itself, it might matter a lot more if you use the break to actually exercise.
There’s also the much trickier scientific question of the effect of lots of chair time on general health, which is an active controversy with some people declaring a crisis of sedentariness and others warning that “couch potato shaming” is irresponsible fear-mongering. I explore this controversy fully in another article, The Trouble with Chairs. But we don’t need a firm answer here, because it’s clear that lots of sitting is at least somewhat unhealthy, and the controversy is really just about how unhealthy it is. We can safely bet that regularly interrupting our chair time with a bit of easy exercise is worthwhile.
I think there are also some hard-to-measure psychological benefits to breaking up the day with little doses of activity, especially with other people — and there is evidence of that too.10
Is microbreaking enough?
We don’t know exactly how unhealthy sitting is, or why, so it’s impossible to know what the solution is. It’s possible that nothing can fully compensate for excessive sitting. It could be a losing battle. Or perhaps the only defense is three half hour workouts at the gym every dang day. This lots of little breaks thing is a rational shot in the dark, only partially based on evidence. It’s a pragmatic compromise between what might work and what is reasonably achievable for the average person with a job that involves a lot of time in a chair.
If you are really serious about avoiding the possible health effects of working in chairs, then take the biggest break of all: quit your job and find another one that involves more exercise! Which is not all that radical a concept. People have certainly quit jobs for less. Many people can’t imagine sitting all day, and would never tolerate it.
But for those of us who are going to keep working in a chair …
You have to actually “exercise” on your microbreak: it’s not enough to just get up
Getting up and doing anything is probably better than nothing, but good microbreaks definitely involve more than a trip to the water cooler. A microbreak really means a tiny workout. Some parameters:
- At least one minute, but probably no more than five.
- A little more time if the exercise is very light. A little less if you’re actually challenging muscles.
- The heart rate must increase at least 30%, but if you need a shower you’ve left “micro” behind and entered “macro” exercise territory. Aim for a “glow.”
Good examples of microbreaking workouts:
- 3-5 flights of stairs.
- 5 each of three classic bodyweight exercises: pushups, crunches, squats. This takes less than one minute.
- Three minutes of dynamic joint mobility drills (see below).
- Two minutes of dancing?
The “music dance experience” on Severance, the surreal sci-fi office horror-comedy-drama series.
A common objection to a microbreaking prescription is “But I get up at work all the time!” Sure you do. Most people do. At the very least, you probably get up to get water and use the bathroom.11 You get up to go the photocopier or fax machine, to run something by your boss, to get the big hole punch, and so on.
Some of you might be getting up to stretch — unaware that stretching is over-rated as a form of therapeutic exercise.12 It doesn’t cut it, although the movement and sensory stimulation probably does qualify as "better than nothing."
You have to do something a little bit challenging with microbreaks. “Something therapeutic” means some kind of significant stimulation — the most perfectly opposite of whatever you are normally doing at work, within the bounds of what is practical to do for one or two minutes. Mobilizations are probably the most practical choice.

Mobilizations: massaging with movement on your microbreak
Mobilizations (AKA dynamic mobility drills) are repeated, rhythmic movements. This is a lot like stretching, but with ants in your pants. More technically (a lot more technically): mobilizations repeatedly and substantially contract and elongate all or most of the musculature around a joint or in a region.
It’s basically therapeutic wriggling. The subject of mobilizations is thoroughly covered in Mobilize!.
Everybody mobilizes instinctively, sort of. Everyone squirms, wrenches, twists, trying to wiggle free from stiffness, active trigger points (muscle “knots”). Yawning and stretching (pandiculation), repeated once or twice, accompanied by sighs and groans, grimaces and joint pops, are extremely common reflexive behaviours seen in the caged human animal. These movements “take the edge off,” and then subside.
Do more than take the edge off. That’s all mobilizing is: nothing more than following that instinct, more rationally, more systematically, above all more repetitively. Does rolling your head around once or twice feel good? Necessary? Then do it several more times!
|takes the edge off
Contrasting mobilizations with stretching
Taking a break just to stretch is almost comically irrelevant to the problem. The problem is stagnation, stillness. Ergo, stretching is a bit off the mark.
(Some people have a rather dynamic stretching style, much like mobilizing. Ironically, they tend to feel kind of guilty for not “holding” their stretches longer. Also, although a lot better than static stretching, dynamic stretching still tends not to be systematic and repetitive enough to constitute a real antidote for all that stagnation in the chair.)
Again I’ll emphasize that anything is better than nothing, but old-school “hold it for sixty seconds” static stretching is not an ideal solution for a sedentariness problem.
Oomph! Can you strength train on your break?
Strength training is any kind of exercise that requires more force from your muscles than you usually ask of them, and that is a very low bar for a lot people. The number one public misconception about strength training is that it’s an exclusive culture of gym nuts that has to involve massive equipment, grunting, and buckets of protein powder. Nope. The truth is that strength training is highly efficient: easy to moderate workouts provide terrific bang for buck, and the benefits diminish steadily with more intense workouts.
Doubtful? I have a whole article about how efficient strength training is, and how it’s not just for gym rats.
Obviously it helps to have a few gym machines or barbells around, but there are many very accessible exercises that require no equipment at all, or only very simple and light equipment (like elastic exercises bands).
More, more, more! Many small breaks are better than a few large ones
The frequency of your natural breaks is probably not enough. Most office workers, in my experience — especially engineers, programmers and other assorted geeks (I’m one of you) — just do not get up often enough to compensate for all the sitting. Even drinking water full tilt and going to the bathroom every hour, on the hour, is probably just not enough.
For every thirty minutes of stagnation, you should have at least one minute of stimulation: the 30:1 rule. It’s not much of a “rule” though, because there is no scientific basis for it; it’s just advice based on years of experimenting with the balance between sedentary productivity and physical activity.13
What about standing to work? Is that enough stimulation?
Standing to work (standing desks) has been gaining popularity as an answer to the perils of sitting. However, standing seems to be just another form of stagnancy, with its own hazards. The Cornell Human Factors and Ergonomics Research Group identifies a number of problems with standing to work:
Standing to work has long known to be problematic, it is more tiring, it dramatically increases the risks of carotid atherosclerosis (ninefold) because of the additional load on the circulatory system, and it also increases the risks of varicose veins, so standing all day is unhealthy. The performance of many fine motor skills also is less good when people stand rather than sit.
They conclude with the advice to mainly sit to work but get up and move regularly:
The key is to build movement variety into the normal workday.
In other words, take microbreaks.
Uh oh, another “should”: the tedious burden of it all
“Don’t should on yourself,” a counselling mentor told me once. “And don’t should on other people.” The last thing anyone needs is another thing we “should” do. By far the worst thing about microbreaking, its greatest weakness as a therapeutic strategy, is that it’s in that exasperating category of “yet another thing I’m supposed to remember to do for my own good.” We have too many of these already, and I try to inflict such advice on people as little as possible.
But in this case it’s unavoidable. It’s a high priority should.
As explained in other articles more thoroughly, sitting a lot is corrosive to our health in many ways. In particular, it may also make us more vulnerable to chronic pain, and likely back pain in particular — there’s an epidemic of back pain in industrialized nations, and it’s sitting could be the reason why.
A career in a chair, like long distance running, is an exercise in seeing how much your body can put up with: not everybody can do it, and nobody can do it forever. Not without consequences.
Microbreaking is something you simply cannot afford not to learn, not if you expect to get through years of sitting unscathed. Every chair warrior needs several survival strategies, but this is the most important, the most inescapable of them.
And yet … it’s kind of tricky.
Teaching old dogs new tricks: strategies for remembering to take a microbreak
Almost everyone has trouble remembering to get up every twenty minutes. I’ve had engineers tell me flat out, “Forget it. I’m not doing it. I can’t do it. If it breaks me, fine, I’ll stop when I break.” That is their prerogative, of course, and yours — when I was a massage therapist,14 I got many years of regular business from people with that attitude!
But most people, I hope, will choose not to run themselves into the ground, and accept that sitting in a chair comes with a price: a certain inevitable chronicity of stiffness and pain, and, to keep it in check, a microbreaking habit as regular and essential as flossing. The question is not if but simply how. Here are some of the best strategies I’ve seen my clients use for building and sustaining a microbreaking habit:
- Do your best to keep it from being a “should” by simply attaching the habit to your own natural instinct to mobilize. Simply “convert” your normal twists, turns and squirms into more positive and systematic mobilizations.
- Use timing software, which will interrupt your work at regular intervals. Many people find that such automated interruptions quickly become just another bit of background noise in their life, all too easily ignored, but others find them effective (at least in phases.) An egg timer will get the job done and most people have one handy, but a clever app can do much more for you — like taking you through specific mobilization exercises, to make the most of your break. There are several apps available, of course. I like one for Mac called TimeOut.
The Apple Watch has an unusually good method of reminding people to get up and move around. It stands out in two ways:
I am completely committed to “closing my rings” every day. The blue ring is the “stand” goal, which you achieve by getting at least a minute of activity per hour. Sounds easier than it is!
- Extremely simple and completely automated. You never have to think about this feature. There is nothing to configure or play with, and it behaves in exactly the same simple way all the time. By default it’s “conservative,” setting a goal of just one minute out of the chair per hour. That’s not enough, but it’s also highly achievable, so it’s unlikely to become frustrating.
- The beautifully engineered physical “tap” that the watch uses to get your attention is exactly right. It doesn’t feel technological — it feels like a polite nudge that is impossible to miss but also easy to ignore. It manages to effectively remind me without ever irritating me — which is quite an accomplishment.
It’s an expensive solution, of course — those watches aren’t cheap — but they have many other features. It’s certainly worth considering, if you’re already an iPhone user. I have experimented with all the various technological reminders for a long time, but nothing ever stuck like this has — I’ve been using it successfully and regularly for years now, far longer than any other method.
- Maybe the high tech is not for you. A simple egg timer can have quite a different psychological “feel” than microbreaking software. Many people insist that, even if they forget or neglect to set the timer some of the time, it is a more forceful interruption.
- The hydration strategy is not bad, but remember that it doesn’t usually generate quite enough breaks — even full-steam-ahead water drinking usually doesn’t make most people need to pee more than about once an hour.
- The “revolving chairs” system marries microbreaking to another self-preservation strategy: rotating between seating arrangements. Using a chair/stool combination with a wobble cushion gives you effectively four different ways of sitting (chair with/without cushion and stool with/without cushion). Some people find it easier to remember to change how they are sitting than to microbreak, so coupling the two together can be quite effective.
- For a lot of hard workers, changing mental focus regularly is unacceptable, and so they have found that they can microbreak without a work stoppage. I advise these people to microbreak by simply standing up and mobilizing the back and hips while still typing and mousing. While I question their sanity and priorities, I actually understand all too well — consider how many hours I’ve invested in this website! And there isn’t really any reason to stop working, as long as you actually do move your back and hips.
There are countless more solutions, one for every individual. Good luck … and happy microbreaking!

This large study of 70,000 Danish workers concluded that taking breaks to do tiny workouts — micro-exercises to build strength — prevented at least 10% of long-term absences from work due to injury and illness. That is a big benefit, easily achieved, and it might be the best evidence available to date that even low-hanging fruit exercise is worthwhile — although it may have as much to do with complex social factors as getting stronger.

In their big Danish study, Andersen et al. noted that the benefits they detected have not been found in home micro-exercise programs. Micro-exercising at work tends to be more social, which probably has all kinds of complex benefits:
The underlying mechanisms of LTSA prevention from micro-exercise during working hours are likely to be multifactorial in nature, including both physiological, psychological and social factors.
Whatever the active ingredients may be, they acted equally on everyone regardless of age, sex, or education. Exercise is good for a lot of people, and micro-exercise appears to be particularly easy and helpful, making its benefits accessible to countless people who would otherwise not exercise at all.
- Some people deliberately drink extra water as a way of forcing themselves to take breaks. This is often motivated by an unjustified fear of dehydration, unfortunately. But, on the bright side, a little extra water is legitimately useful for preventing kidney stones!
- Stretching is not a pillar of fitness: no type of stretching is a warm up, prevents or treats soreness or injury in general, or enhances peformance (but it can actually backfire). It can increases flexibility, but the value of flexibility is low, even for most athletes. Stretch seems to have almost no value in treating any common kind of chronic pain. For more information, see Quite a Stretch: Stretching science has shown that this extremely popular form of exercise has almost no measurable benefits.
- It’s not that 30:1 is biologically optimal — less could be sufficient, more might be necessary, no one knows — it’s just a rough compromise between doing as much as possible and how much interruption we can tolerate.
