Is Sitting Really That Bad? Movement Snacks for Long Workdays
Sitting is not dangerous in itself, but long, unbroken stretches of it are linked to poorer health, and an hour in the gym does not fully cancel out a day spent almost motionless in a chair. The UK Chief Medical Officers’ guidance asks adults to reduce sedentary time and break up long periods of sitting with at least light activity. The practical answer is the movement snack: a one- to five-minute burst of walking, stairs or simple exercises, repeated through the day, so that you rarely sit for more than an hour at a time.
What the evidence actually says
The headline “sitting is the new smoking” overstated things. What researchers have consistently found is that high amounts of sedentary time are associated with a higher risk of type 2 diabetes, cardiovascular disease and early death, and that this association is only partly offset by doing formal exercise. Physical inactivity and sedentary behaviour are related but separate: you can meet the activity guidelines with three runs a week and still be highly sedentary the rest of the time.
That is why the UK Chief Medical Officers’ physical activity guidelines include a separate line on sitting, alongside the familiar recommendations of 150 minutes of moderate activity a week and muscle-strengthening work on at least two days. The guidance is deliberately undramatic: minimise time spent sedentary and, when physically possible, break up long periods of inactivity with at least light physical activity.
Note the word “light”. You do not need to break a sweat at your desk. The aim is frequent interruption, not hard work.
Why movement snacks make sense for busy people
Most of the people I train in Highgate work long days, many of them in back-to-back video calls. They do not lack motivation for their sessions; they lack natural movement between them. Commuting by tube, lunch at the desk and a car for the school run can leave a day with remarkably few steps.
Movement snacks work because they cost almost nothing. They need no kit, no change of clothes and no shower. They also do something for the way the day feels. Stiffness in the hips, neck and lower back after a long stretch of sitting is common, and getting up every so often tends to keep it in check. Many people also find a short walk clears their head better than another coffee.
They are not a substitute for strength training or for the activity guidelines. They are the layer underneath, the habit that keeps the rest of your day from being entirely still. If you want the bigger picture on daily movement and energy use, our post on NEAT covers the calories side.
A menu of movement snacks
Choose two or three that suit your workplace and rotate them. Each takes one to five minutes.
| Snack | Time | Where it works |
|---|---|---|
| Brisk walk round the block or the floor | 3-5 min | Anywhere, best between meetings |
| Two or three flights of stairs, up and down | 2-3 min | Offices, flats, stations |
| 10 bodyweight squats to a chair | 1 min | Home office or a meeting room |
| 10 calf raises plus 10 slow hip hinges | 1 min | Beside the desk |
| Wall or desk push-ups, 10 reps | 1 min | Home office |
| Doorway chest stretch and neck turns | 1-2 min | Anywhere |
| Walking phone call | Length of the call | Any call without a screen share |
Stairs deserve a special mention. They raise your heart rate quickly, need no equipment, and are available in nearly every London building. Even a couple of flights a few times a day adds up to meaningful extra work for the legs.
How to actually do it: a simple system
The difficulty is never knowing what to do. It is remembering to do it when the inbox is full. The people who make it stick use structure rather than willpower.
- Set a default interval. Every 45 to 60 minutes of sitting, stand and move for at least two minutes. A repeating reminder, a smartwatch prompt or a kitchen timer works.
- Attach snacks to existing triggers. End of a call, refilling water, before opening email after lunch. Linking a new habit to an existing one is more reliable than relying on memory; we cover the method in habit stacking for fitness.
- Book 25- or 50-minute meetings. Ending early gives everyone a few minutes to move before the next one.
- Make one call a day a walking call. Audio-only catch-ups are ideal.
- Keep a count, not a plan. Aim for six to eight snacks in a working day. Tally them on a sticky note for the first fortnight.
A sample workday
- 9.50: end of first call, two flights of stairs.
- 11.00: squats and calf raises while the kettle boils.
- 12.30: ten-minute walk before lunch.
- 14.00: walking phone call.
- 15.30: desk push-ups and a doorway stretch.
- 17.00: stairs again, then a short walk to finish the day.
None of that is exercise in the training sense. Together it changes a day of eight hours seated into a series of shorter blocks.
Common mistakes
- Treating a standing desk as the answer. Standing still all day is not much better than sitting still. Alternating positions and moving is what helps. We discuss this in standing desk or sitting desk.
- Making the snacks too hard. If you need a shower afterwards, you will not do it at 11am on a Tuesday.
- Saving it all for the evening. A long walk after work is good; it does not break up the sitting before it.
- Abandoning it on busy days. Those are the days with the most sitting. Keep at least two or three snacks, even if it is only stairs.
If you have a heart condition, are pregnant, or have joint or back problems that make some movements painful, check with your GP about what is suitable before adding new exercises.
Where structured training comes in
Movement snacks keep the day from being static. Strength training does a different job: building and maintaining muscle, bone and the capacity to do more. Both matter, and they support each other. Clients who move regularly during the day usually arrive at sessions less stiff and warm up faster. In 1-1 personal training in Highgate, we plan the gym sessions and also help you build the daily habits around them, with early morning and evening slots that fit around work.
Questions we get asked
Does exercise cancel out sitting all day?
Partly. Regular exercise reduces many of the risks linked to sitting, but it does not fully remove the effect of very long sedentary periods. Doing both is the safer bet.
How often should I get up from my desk?
There is no official number. Getting up at least every hour, ideally every 30 to 45 minutes, is a sensible and achievable target.
Do movement snacks help with weight loss?
They add to your daily energy use, which helps a little over time, but diet and overall activity matter more. Think of them mainly as a health and comfort habit.
What if I work from home?
It is often easier: stairs, the kitchen, a short walk round the block. The risk is that home days are more sedentary, so use reminders. You can read about how we work with desk-bound clients on our personal trainer page.
