Sitting all day at work: a movement break every hour

How long the break needs to be, what to do in those few minutes, and how to make it stick on days when meetings run back to back.

You sit down at nine, and the first time you properly stand up is around one, because you're hungry. The question isn't whether you should move more often — it's how to do it when your calendar owns the day and you forget everything the moment the first message lands. So: how long the break needs to be, what to do in it, and how to keep it alive during a bad week.

How long the break needs to be

Two to five minutes for every hour of sitting is the figure that survives contact with real work. Under two minutes and you've only stood up and sat back down; over five and it starts eating into the task, and a habit that interferes with work rarely lasts a month.

Across an eight-hour day that's six to eight stand-ups and 15 to 30 minutes of movement that otherwise wouldn't exist. If half of it is walking, you've picked up roughly 1,000 to 2,000 steps without going looking for them.

Exactly how many minutes counts as "enough" isn't settled, and the answer shifts depending on what's being measured — stiffness, low back pain, afternoon concentration, blood sugar after meals. What the evidence keeps showing is that several short interruptions spread through the day beat one long outing.

What to do with those few minutes

Walking is the default and doesn't need replacing. A corridor, a flight of stairs, a trip to the kitchen tap — that's the break. Everything else is an add-on, worth doing only if something specific is bothering you.

Walk for two to three minutes — down the corridor and back, one floor up and down, over to fill a glass.
Ten to fifteen squats if you want your legs and hips to remember they exist. No tempo, no counting sets.
Hip openers — a lunge with the back leg long, 20 to 30 seconds a side. This is the one desk workers usually feel straight away.
Chest and upper back — hands behind your back, shoulders drawn back, head staying over your ribs. Twenty seconds is plenty.

Don't build an eight-exercise routine. Three things you know by heart will survive a bad day; an eight-step plan won't make it to Wednesday.

Remembering to stand up at all

A phone reminder works for about three weeks, then you start dismissing it without reading it. What lasts longer is hanging the break on something that already happens — the end of a call, sending a report, an empty water bottle. It's the same reason a trigger inside a routine you already have holds a habit better than good intentions do.

Two small changes do a lot of the work: keep your water in the kitchen rather than on the desk, and take phone calls standing. That's three or four stand-ups a day with no reminder involved.

Working from home, tie it to the washing machine, the post or the bin. In an office, the printer and the stairs are on your side.

Standing desks and other kit

A desk that raises helps mainly by lowering the effort needed to change position. Standing for eight hours isn't the answer either — it's a different way of holding still, with sore feet and a tired low back thrown in. Alternating is the point: 30 to 45 minutes seated, then 15 to 20 standing.

If you haven't got one, you haven't lost much. Getting up every hour delivers most of the benefit and costs nothing. Before buying anything, check the cheap things: screen top roughly at eye level, feet flat on the floor, knees about level with your hips.

Days packed with meetings

A day with five back-to-back calls is not a day for eight breaks. The target changes: two stand-ups before lunch and two after, not eight.

Take listen-only calls on your feet with the camera off. Between two meetings there's almost always 60 to 90 seconds — enough to stand, straighten up and walk to the door and back. That isn't a token gesture; the gap between zero and two stand-ups in five hours matters more than the gap between six and eight.

What this habit won't fix

Hourly breaks don't replace training and won't move the scales on their own. Their effect runs through total daily expenditure, and how much a desk job takes out of that total is its own story — short breaks give back part of it, not all.

For back and neck pain, the evidence is strongest for changing position rather than for holding one correct posture. The best chair, in other words, is the one you get out of. If pain has been with you for months, breaks are support, not treatment.

The first two weeks

Don't start this alongside a new training plan or a new diet — two new habits at once tend to cancel each other out, and the less visible one usually goes first.

Judge it by days, not by perfection. Four stand-ups on a day that used to have one is a win. If you want an anchor for the afternoon, a walk after lunch is the easiest place to start, because the time is already fixed.

After three or four weeks you'll notice yourself standing up without a prompt. That's the point where it stops being something you track and becomes part of the day.

When to see a doctor

Get checked if you have numbness or weakness in an arm or leg, pain that wakes you at night, swelling or pain in one calf, or repeated dizziness on standing. The same goes for low back pain lasting more than six weeks with no sign of easing. A movement break is a good habit, but it isn't a test for any of this.

The short version

Two to five minutes of movement per hour of sitting; six to eight stand-ups across an eight-hour day.
Walking is the base — squats, hip openers and a chest stretch are optional extras.
Attach the break to something that already happens instead of relying on a reminder.
On a packed day, aim for two before lunch and two after, not eight.
It supplements training and supports your back; it replaces neither.
