Few pieces of health advice are as widely repeated, or as shaky, as “fix your posture”. Most of us grew up being told to sit up straight and pull our shoulders back, as though one correct position stood between us and a lifetime of back pain. The research tells a more interesting and far more relaxed story. There is no single perfect posture, and the exercises worth doing are not the ones that drill you into a rigid shape – they are the ones that keep you moving and strong. Here is what actually has evidence behind it, and what does not.
The Idea of “Correct” Posture Is Mostly a Myth

There Is No Single Right Way to Sit or Stand
For decades, the advice was simple and stern: sit up straight, pull your shoulders back, and hold the one correct posture that would spare your spine. It turns out the evidence never really supported that picture. Large reviews of the research have repeatedly failed to find a single ideal posture that reliably prevents back or neck pain, or one bad posture that reliably causes it. People with what looks like poor posture are often pain-free, and people who sit immaculately still get sore.
This matters because the myth does harm. When someone believes their slouch is slowly damaging them, every relaxed moment becomes a source of worry, and that fear itself is associated with worse pain outcomes. The more useful message from the research is gentler and more freeing: there is no posture you need to hold perfectly. Your spine is a robust, adaptable structure, not a tower of blocks that topples the moment you slump. What you do with your body over time matters far more than the shape you hold in any given second.
The Best Posture Is the Next One
If there is a single principle the evidence supports, it is this: the best posture is your next one. The body does not cope well with staying in any one position for hours, even a textbook-perfect one. What the research more consistently links to discomfort is sustained stillness – holding a fixed position long enough that tissues load unevenly and stiffness sets in – rather than the particular position itself.
This reframes the whole goal. Instead of chasing a perfect static posture, the aim is to keep changing. Shifting in your chair, standing up, walking to fill a glass of water, rolling your shoulders, alternating how you sit – this gentle variety is what keeps a spine comfortable through a long day. It is also a far easier instruction to follow than rigid vigilance. You do not have to monitor yourself every minute; you simply have to avoid turning to stone. Movement, not perfection, is the active ingredient.
What Actually Has Evidence Behind It

General Strength and Fitness Beat Posture Drills
When researchers compare approaches for preventing and easing back and neck trouble, the most consistent winner is not a clever posture drill – it is general exercise. Staying physically active and building overall strength has better and more reliable evidence behind it than any specific attempt to correct how you hold yourself. A body that is stronger and fitter simply tolerates the ordinary loads of daily life more comfortably.
The practical takeaway is liberating for anyone who has been told they need to fix their posture. You are usually better served by regular, enjoyable movement – walking, swimming, cycling, resistance training, whatever you will actually keep doing – than by fussing over the exact angle of your shoulders. New Zealand’s Healthify health information service and most evidence-based guidelines point the same way: consistent activity is the foundation, and specific exercises sit on top of it rather than replacing it. Build the base first.
Strengthening Through the Back and Trunk
On top of general fitness, strengthening the muscles around the spine has reasonable support, particularly for people prone to recurring back pain. The aim is not a rigid “core” obsession but a trunk and back that can comfortably do their job of supporting and moving you. Exercises that gently load the back and trunk – bridges, bird-dogs, gentle back extensions, and general resistance work for the hips and legs – all contribute, because the spine does not work in isolation from everything around it.
The honest caveat is that no single magic exercise has emerged from the research; variety and consistency matter more than any particular movement. A reasonable approach is a small handful of strengthening exercises done regularly rather than an elaborate routine done once and abandoned. If you have an existing condition or your pain is significant, this is the point to work with a registered chiropractor, physiotherapist, or your GP, who can tailor and progress things safely rather than relying on a generic list.
Moving the Mid-Back That Sitting Stiffens
One area worth singling out for desk-bound New Zealanders is the mid-back, or thoracic spine – the section that tends to stiffen under long hours of sitting and screen work. Gently restoring movement here is less about correcting a fault and more about countering the stillness that a sedentary day imposes. Simple mobility movements – rotating the upper body, reaching overhead, extending gently back over a chair, or rolling the shoulders through their full range – help that region keep moving freely.
Think of these as movement snacks rather than a workout: a minute every hour or two, woven into the day, doing more good than a single long session. The benefit is partly mechanical and partly just the act of interrupting sustained sitting. None of this requires special equipment or a diagnosis – it is the kind of unstructured, frequent movement the evidence quietly favours. The goal is a mid-back that is used regularly, not one held in any particular position.
The Things That Do Not Earn Their Reputation
Posture-Correcting Devices and Braces
Posture-correcting braces and the newer wearable “posture trainers” that buzz when you slouch are heavily marketed, and the evidence for them is thin. There is little good research showing they produce any lasting improvement, and the logic is shaky: a device that holds you in a position does nothing to build the strength or movement habits that actually support a comfortable spine. At best it is a temporary external cue; at worst it can foster a kind of dependence, where the body offloads the work to the strap rather than doing it itself.
This fits the broader theme of this article. The appeal of a corrector is that it promises to fix posture passively, while the evidence keeps pointing toward active strategies – movement, strength, and variety. If wearing one occasionally reminds you to move, no harm done, but it is not a treatment and should not replace the things that genuinely help. Your money and effort are better spent on staying active than on a gadget promising to hold you straight.
Ergonomic Gear Without Movement
Standing desks, ergonomic chairs, and specially shaped cushions occupy a similar grey zone. They are not useless, but the evidence does not support treating any of them as a cure. A standing desk, for instance, mainly helps by making it easier to change position through the day – standing for hours is no better than sitting for hours, because the real issue was the staying-put, not the chair. Bought in the hope that the right equipment will fix your back on its own, these products tend to disappoint.
The sensible way to read the mixed evidence is that good equipment lowers the friction of moving and adjusting, which is genuinely worthwhile, but it works with your habits rather than instead of them. A height-adjustable desk you actually use to alternate between sitting and standing earns its place; one you set once and never touch does little. As ACC’s guidance on work-related discomfort reflects, the durable answer is varied movement and a setup that supports it – not a single purchase that promises to do the work for you.
A Calmer Way to Think About Posture
Put together, the research tells a more relaxed story than the one most of us grew up with. There is no perfect posture to achieve and no ruinous one to fear. A spine does best when it is moved often, kept reasonably strong, and not asked to hold any single position for hours on end. The constant self-correction – shoulders back, chin in, sit up straight – turns out to be largely wasted effort, and the worry that comes with it may do more harm than the slouch ever did.
That leaves a simpler set of habits worth keeping: move regularly, build and maintain general strength, and break up long stretches of stillness however suits you. If back or neck pain is persistent, worsening, or affecting your daily life, that is the time to see a registered chiropractor, physiotherapist, or your GP rather than to buy another corrective device. Good posture, in the end, is not a position you hold. It is a body you keep using.
The reassuring thread through all of this is that your spine is far more robust than the posture industry implies. It does not need to be held in formation; it needs to be moved, used, and kept reasonably strong. Drop the constant self-policing, build movement and variety into your day, and treat any persistent pain as a reason to see a professional rather than to buy another strap. The healthiest posture was never a position at all – it was the habit of not staying still.

The ‘there is no single correct posture’ line is going to surprise a lot of people, me included. I have spent years trying to sit up perfectly straight and it never seemed to help. The emphasis on movement and strength makes far more sense.
Thank you for the honest take on posture-corrector straps. I bought one off the back of an Instagram ad and it did nothing except dig into my shoulders. Should have read this first.
