Lower Back Pain From Sitting At A Desk: What Tends To Help

Your lower back aches by mid afternoon, it is worse on the days you have back to back meetings, and it eases off a bit once you get up and move around. Then you sit down again and it creeps back.

This is one of the most common things people mention when they first speak to me. Before anything else, the important bit: I am a personal trainer, not a doctor or a physiotherapist. I cannot tell you what is causing your back pain and neither can any article. If your back is genuinely bothering you, get it looked at properly by your GP or a physio. What follows is general information about how bodies tend to respond to desk work, not a diagnosis and not treatment.

Get it checked first, and get it checked sooner if any of this applies

Most back pain that comes and goes with sitting is not sinister. But some things need a doctor rather than a trainer, and they need one promptly rather than eventually. Book an appointment with your GP without delay if you have numbness or pins and needles in the groin or saddle area, any change in bladder or bowel control, weakness in a leg or foot that is getting worse, pain following a significant fall or accident, unexplained weight loss, fever, or pain that consistently wakes you in the night.

Those are the ones doctors want to hear about early. Even without any of them, if the pain has been hanging around for weeks, or it is limiting what you do, a physiotherapist is the right person to assess it. A proper assessment is worth far more than any general advice, including mine. I would much rather work alongside a physio who has actually examined you than guess.

Sitting is not evil, but staying still for hours is a problem

The usual story is that sitting wrecks your back and that posture is the villain. It is more useful than that. Tissues in the body do not much like being held in one position for long stretches. Blood flow drops, some structures stay loaded in the same way for hours, and the nervous system starts registering the situation as uncomfortable. Then you shift, and it feels better for a while.

That is why the strongest single predictor of an achy back at a desk is not usually how you sit, it is how long you sit without changing anything. A perfect posture held rigidly for three hours is still three hours in one position. Variety of position tends to beat perfection of position.

It is also worth saying plainly, because it worries people: an aching back after a long day at a desk does not mean your spine is being damaged or crumbling. Backs are robust. Discomfort and damage are not the same thing, and believing your back is fragile tends to make people move less, which is usually the opposite of what helps.

Break the day up, and do it properly

The single highest value change for most desk workers is frequent, small interruptions to sitting. Not a heroic gym session at 6pm to make up for eight static hours.

• Stand up and walk about every 30 to 45 minutes. Even a minute is worth having. Fill a glass of water, walk to the other end of the house or office, take a call on your feet.
• Change position deliberately rather than aiming for one perfect posture. Sit back, sit forward, cross your legs, uncross them, stand for a call, perch, sit again.
• If you have a sit stand desk, alternate rather than standing all day. Standing still for six hours creates its own set of aches.
• Take calls that do not need a screen while walking outside. This is the easiest change most people can make and it stacks up quickly across a week.
• Get out for a walk at lunch. Twenty minutes of continuous easy walking does more for a stiff back than most of the stretches people find online.

Mobility where it usually matters: hips and upper back

When the hips and the thoracic spine, meaning the middle and upper back around the ribcage, do not move well, the lower back often ends up doing more than its share. Desk work is quite good at stiffening both. Hips are held in a bent position for hours. The upper back stays rounded and still while you look at a screen.

So rather than endlessly stretching the lower back itself, it is often more productive to spend a few minutes a day encouraging movement above and below it. Things like a gentle hip flexor stretch in a half kneeling position, easy rotations of the upper back while seated or on all fours, and hip movements that take the joint through a decent range without forcing anything. None of it should be painful. Uncomfortable stretch feeling, fine. Sharp or nervy sensations, stop and mention it to a physio.

Five minutes most days beats forty minutes once a week by a distance.

Strengthening tends to do more than stretching alone

This is the part most people have not tried. If your back feels tight, the instinct is to stretch it. That often feels good for about twenty minutes and then everything returns to how it was. Stretching relieves. It does not usually change much on its own.

What tends to help more over weeks and months is building capacity, so the tissues around your hips, trunk and back tolerate load and time better. In practice that means learning to hinge at the hips properly, doing some sensible loaded carries, working the glutes and the muscles down the back of the legs, and training the trunk to resist movement rather than doing endless crunches. Nothing exotic. Just done consistently and progressed slowly.

This is where coaching earns its keep, because the movements that help are also the movements people most commonly do badly on their own. A deadlift pattern done well is one of the more useful things a desk worker can own. Done with a rounded back and too much weight because a video said so, it is a bad afternoon. If you want to see how the sessions are structured, I have written up the way I run things in more detail.

One important caveat. If a physio has given you specific exercises, those take priority over anything general. I work around what they have prescribed rather than replacing it.

What to stop doing

• Stop resting completely. Prolonged rest for ordinary back pain tends to make things stiffer and worse, not better. Gentle movement is usually the better default, and this is worth confirming with your GP or physio for your particular situation.
• Stop searching for a diagnosis online. Scan findings and scary terminology are extremely common in people with no pain at all. Reading about them at 11pm helps nobody. Ask a professional who has actually examined you.
• Stop chasing the one magic stretch. If a stretch has given you twenty minutes of relief every day for a year and no lasting change, it is a coping tool, not a solution.
• Stop the all or nothing pattern. Doing nothing for three weeks, then a punishing session that leaves you unable to move for four days, is one of the most reliable ways to keep a back irritated.
• Stop training through sharp pain. Ever. Discomfort that settles quickly is one thing. Sharp, worsening or nervy pain is a stop signal and a reason to speak to a professional.
• Stop assuming the chair is the whole problem. Equipment helps at the margins. Sorting your chair while still sitting motionless for nine hours, sleeping badly and never loading your hips will not get you far.

The stuff nobody mentions: sleep, stress and load

Pain is influenced by more than mechanics. Short sleep, a stressful stretch at work and general fatigue all tend to turn the volume up on discomfort. Most people notice their back is worse in the weeks where everything else is worse too, which is not a coincidence and is not imagined.

I am not suggesting your back pain is stress and nothing else. I am saying that a bad patch of sleep and deadlines is relevant context, and worth mentioning to whoever is assessing you.

A sensible plan for the next month

Compressed into something you could actually do: get assessed by your GP or a physio, break your sitting up every half hour, walk daily, spend five minutes on hip and upper back mobility, and start some gradual, properly coached strengthening rather than only stretching.

Then be patient. Backs that have been grumpy for two years do not settle in two weeks. Progress usually looks like slightly better afternoons, slightly fewer bad days, and slightly more you can do without thinking about it.

If you want help building the strength side

I train people one to one from a private setup in Cuckfield, and a good chunk of them arrived because of a back that had been niggling for years. Plenty travel in from Haywards Heath, about five minutes by car, and from Balcombe, roughly ten.

Everyone starts with a free, no obligation consultation, which includes a health questionnaire and a movement screen so I can see how you actually move before anything is planned. I will not diagnose your back and I will not promise to fix it. What I will do is build training around it, work with what your physio or GP has told you, and be honest if I think you need to see someone else first. Get in touch and tell me what is going on.
