Sitting All Day: Why Movement at Work Matters — and How to Fix It

For most office teams, the working day is a seated activity. We arrive, sit down, and — between meetings, emails and lunch at the desk — stay there for the best part of eight hours. It feels harmless. It isn't. Prolonged sitting quietly chips away at your team's physical health, energy and mood, and it's one of the easiest workplace risks to do something about. Here's why movement at work matters, and how to build it into your team's week without anyone needing to join a gym.

The hidden cost of a seated workday

The body is not designed to sit still for hours, and the bill for doing so shows up in the sickness figures. Work-related musculoskeletal disorders — the back, neck and shoulder problems that come from sitting badly for long stretches — affected an estimated 511,000 workers in Great Britain in 2024/25, accounting for around 7.1 million lost working days and 27% of all work-related ill health (HSE, 2024/25). These are among the most common reasons people take long-term sick leave.

The problem is simple: modern work removes almost all of the incidental movement that used to be built into a day. There's no walk to a colleague's desk when you can message them, no stairs when the lift is right there, no reason to leave your seat for hours at a time. The result is a workforce that moves far less than its health requires — and feels it.

It's not just backs — sitting affects the mind too

Movement isn't only a physical-health issue. Long, unbroken stretches at a desk take a measurable toll on wellbeing. The ASICS State of Mind study found that just two hours of uninterrupted desk time produced a noticeable decline in participants' mental state, and four continuous hours was associated with an 18% rise in stress levels (ASICS, 2024). Conversely, even short bursts of activity lift mood, sharpen focus and break the mid-afternoon slump.

This is why the World Health Organization's 2020 guidance did two things: it recommended adults get 150 to 300 minutes of moderate activity a week plus regular muscle-strengthening, and — for the first time — it explicitly advised people to reduce and replace sedentary time (WHO, 2020). For a desk-based team, the workplace is exactly where a large share of that sedentary time accumulates. It's also, therefore, where the fix belongs.

What "movement at work" actually means

Good news: the answer is not turning the office into a fitness centre. Meaningful change comes from a mix of small habits and a little structure.

Build in micro-breaks

Encourage people to break up sitting roughly every 30 minutes — stand for a call, walk to fill a water bottle, take the stairs. These two-minute interruptions are modest on their own but add up across a day, and they're the single easiest thing to start today.

Set the space up to help

Basic ergonomics — a properly adjusted chair and screen, the option to stand for part of the day — reduce the strain that leads to those musculoskeletal problems in the first place. Small equipment changes prevent big absence costs.

Add structured movement sessions

Habits stick far better when there's a shared, scheduled anchor in the week. A regular on-site session — desk-based fitness, a stretch-and-mobility class, or gentle yoga — gives the whole team a reason to get up, move together, and reset. It also teaches people the simple movements they can then repeat at their desks.

Keep it inclusive

The fastest way to kill a movement initiative is to make it feel like a fitness test. Not everyone runs marathons, and some of your team may be managing injuries, joint issues or simply a long absence from any exercise at all. Choose formats that meet people where they are — low-impact, adaptable, and led by a qualified instructor who can offer easier and harder versions of each movement. When a session is genuinely accessible, participation climbs, and the people who would benefit most are the ones most likely to take part rather than quietly opt out.

Why on-site sessions beat "just move more"

Telling a tired team to "move more" rarely works, for the same reason unused gym benefits gather dust: it asks people to find the time, energy and motivation on their own. Bringing a qualified instructor into the workplace during the working day removes all of that friction. Movement becomes something the team does together, in work time, with zero admin for the individual — and that's what turns good intentions into a genuine habit. A weekly desk-based fitness or movement class is one of the simplest, most visible ways to show a team their wellbeing is taken seriously.
