Most low back pain in office workers isn’t about the chair. It’s about how much sitting you do, how rarely you change position, and how strong the muscles around your spine are. Three things you can change without buying anything.
We see hundreds of office workers a year across our Sydney clinics — CBD, Castle Hill, Caddens — and the conversation is usually familiar. The back has been niggling for months. It gets worse on Thursday and Friday. Sundays are fine. Tuesdays are fine. By Friday afternoon, getting out of the office chair feels like work.
If that pattern sounds like yours, the good news is that the fix doesn’t require an MRI, a new chair, or a course of treatment that costs more than your weekly groceries. It requires you to act on five things, in order.
1. Move more often, not less
The single biggest predictor of back pain in office workers isn’t sitting badly — it’s sitting for too long without changing position. The body adapts to whatever position you spend most of your day in. Eight hours of any one position, no matter how "correct," will eventually cause problems.
Practical version:
- Get up at least once an hour. Set a timer if you have to. The Pomodoro 25-minute work block works for this if you already use it.
- Take phone calls standing up. Most calls in an office don’t need both hands on a keyboard.
- Walk for water rather than topping up the bottle on your desk. The walk is the point, not the water.
- Have lunch away from your desk at least three days a week. Outside if you can.
None of that requires a sit-stand desk, although those are fine if your employer offers one. The desk doesn’t fix the problem; changing position regularly does.
2. Strength is more important than posture
Posture is a position, not a fix. You can sit in textbook-perfect posture and still develop back pain if you do it for ten hours a day with no break and no underlying strength to support it. The research is consistent on this: posture correlates poorly with back pain. Strength correlates well.
For most office workers, the muscles that quietly weaken are the deep stabilisers around the trunk and hips, and the bigger movers that hold the back upright against gravity. The fix is two short strength sessions a week, not three hours in the gym.
A reasonable starting point — 20 minutes, twice a week, with whatever equipment you have:
- Bridges (10 reps, 3 sets) — strengthens glutes and hamstrings, settles low back
- Bird-dog (10 each side, 3 sets) — trunk stability, paraspinal endurance
- Goblet squats with a kettlebell or dumbbell (8 reps, 3 sets) — whole-body strength
- Dead bugs (8 each side, 3 sets) — anterior core control
- Plank or side plank holds (20–40 seconds, 3 each side) — trunk endurance
If you’ve never done strength training before, see a physio or a trainer once to learn the basics. After that, the work is yours to do.
3. Make Friday Friday again
The Friday-afternoon pattern is real and worth taking seriously. By Friday the back has accumulated a week of load and not enough recovery. The fix is partly about better midweek breaks and partly about how you finish each day.
Three small habits that change the Friday picture:
- A 10-minute walk at the end of each working day before sitting in your car or on the train. Most Sydney office workers can get this in by walking to a slightly further station or coffee shop.
- A few minutes of decompression on the lounge in the evening — knees up, head supported, just breathing. Not stretching, not phone-scrolling. Resting.
- Sleep on your side with a pillow between your knees, or on your back with a pillow under the knees. Avoid sleeping on the stomach if you can — it loads the lower back over many hours.
4. Don’t rush to imaging
Most office-worker back pain doesn’t need an MRI. The findings most people are scared of — disc bulges, mild degeneration — are present on the scans of pain-free adults too. Scans change management when symptoms specifically suggest a nerve-root problem, a fracture, or when surgical decisions are on the table.
For ordinary, mechanical, "stiff and sore" back pain, imaging in the first six weeks is more likely to scare you than help you. Your physio will tell you honestly when a scan would change the plan — and when it wouldn’t. More on this in our condition guide.
5. See a physio sooner rather than later
The longer back pain has been there, the longer it takes to settle. People who come in within the first month of a new flare typically settle in four to six weeks. People who wait six months often need twelve weeks. The work isn’t harder, there’s just more of it.
A good first appointment is 45–60 minutes. The clinician should take a proper history, watch you move, examine the back and hips, and give you a plain-English explanation of what’s going on. You should leave with a written plan you can run from home, not with a sales pitch for a block of ten sessions.
Our physiotherapy service page covers what to expect; the mobile team visits CBD offices and apartments if leaving work isn’t practical. Whichever way you come in, the goal is the same: short course of treatment, a few simple things to do at home, and back to a Friday that feels like a Friday.
When to come in sooner
Some patterns warrant a faster appointment. Book in this week if:
- the back pain has been there for more than three or four weeks without easing
- pain or numbness is travelling down a leg
- you’re losing strength in a foot or leg
- sleep is being disrupted
- you’re changing how you do daily tasks to avoid pain
Loss of bladder or bowel control, or numbness in the saddle area, is the rare red flag — go to a hospital emergency department, not us.
What about ergonomics — chairs, desks and screens?
Ergonomics matters, but the effect is smaller than the marketing suggests. A reasonable office set-up does help; a perfect one does not unlock pain-free productivity. The high-value adjustments, in order:
- Top of screen at or slightly below eye level. Stops the chin-poke that drives neck and upper-back pain.
- Elbows roughly at desk height, shoulders relaxed. Most people can fix this with a chair adjustment alone.
- Forearms supported when typing for long stretches. Wrists neutral, not bent back.
- Feet flat on the floor or on a footrest. Knees roughly level with hips.
- Frequent change of position matters more than nailing the textbook setup.
If your employer has an ergonomics service, use it. If not, a single physio appointment with a workplace focus is usually enough to sort the configuration. Private health funds typically cover the assessment.
Final thought
There’s nothing exotic about getting on top of office-worker back pain. It’s the same advice as a hundred years ago, refined by better evidence: move more, build a bit of strength, sleep well, and get a clinician to help when it’s been there too long. Most people don’t need a course of treatment that lasts months. They need a clear plan, executed for six weeks.
If you’re a Sydney office worker dealing with persistent back pain, book a 45-minute initial assessment at our CBD, Caddens or Castle Hill clinic — or have the mobile team visit your office or apartment.
