Getting up and moving roughly every 30 to 60 minutes is the part that seems to matter most for desk aches — more than any specific stretch.
The short version
- Studies that broke up sitting with short standing or movement breaks found less lower back discomfort and less fatigue during the workday.
- A minute or two is enough.
Why it happens
Sitting still in one position for a long stretch is what tends to build up the ache, rather than sitting itself. When researchers watched office workers through a long sitting bout, discomfort climbed steadily the longer people stayed put, and workers naturally started shifting around more as it built up.
The good news is the fix is small. In one workplace trial, staff who swapped between sitting and standing every 30 minutes across the day reported clearly less lower back discomfort and less tiredness than on days they just sat — and they got the same amount of work done. Other work has looked at short active breaks with a few gentle movements every half hour and found similar benefits for back load.
What the research doesn't really show is that one magic stretch is better than another. So don't overthink the choice of movement. Changing position often is doing most of the work.
⚠️ When to see a doctor in person
Get emergency care straight away — go to A&E or call 999 if you have numbness around your groin, genitals, or the area you'd sit on (saddle numbness), a change in genital sensation, sudden loss of bladder or bowel control, or leg weakness that's getting worse. These can be signs of a rare problem where nerves at the base of the spine are being squeezed, and it needs same-day emergency treatment.
- Book an appointment if pain wakes you at night, spreads down an arm or leg with pins and needles, or hasn't improved after a couple of weeks of moving more and changing your setup.
Most desk-related aches settle once you change position more often.
A simple break you can do at your desk
Aim for one round every 30 to 60 minutes. The whole thing takes about a minute.
- Stand up and walk 20 steps. Even to the kitchen and back. This is the most important part.
- Chin tucks — 5 reps. Sitting or standing tall, gently draw your chin straight back like you're making a double chin. Hold 3 seconds. You should feel a light stretch at the back of the neck, not a pinch.
- Shoulder rolls — 10 reps. Roll your shoulders backwards in a big slow circle.
- Standing back arch — 5 reps. Hands on your lower back, gently lean backwards a small amount. Stop where it feels like a stretch, not a strain.
- Sit-to-stand from your chair — 5 reps. Stand up and sit down without using your hands, slow and controlled.
Keep everything gentle. None of these should hurt.
Progression note
If an hourly reminder feels like too much at first, start with three or four breaks spread across the day and build from there. Once the habit sticks, the useful next step is usually adding some general strengthening or walking outside work hours — desk breaks help the day, but they don't replace regular exercise.
Bottom line
The evidence points at frequency, not at any particular stretch. Standing up and moving every 30 to 60 minutes is linked to less back discomfort and less fatigue across a workday. Pick a few easy movements you'll actually repeat, and set a reminder.
