Most stretching advice is written for people who already stretch. This is written for the other situation: you sit for most of the day, something feels tight, and you would like to know what is worth doing without taking up a hobby.
It is the hub for the rest of our writing. Each section is the short version, with a link to the longer one.
What sitting actually does
A chair holds your joints at fixed angles for hours. That is the whole mechanism, and it is less dramatic than the internet suggests.
Five consequences account for most of what people notice:
- Hip flexors sit short. A seated hip is a folded hip. Hold the fold for eight hours and the front of the hip stops offering its full range easily.
- Hamstrings sit slack and unused. Length is not the only thing that changes; so does how willing they are to lengthen.
- The lower back holds one shape. Rounded forward, with the muscles either side holding a position rather than changing one.
- The chest closes. Arms forward on a keyboard pulls the shoulders round.
- The head drifts forward of the shoulders. The neck then carries it at an angle it was not built to hold all day.
None of that is a diagnosis, and this page is not the place to get one. It is a description of joint angles, and joint angles respond to being changed.
The five areas worth your time
If you only ever stretch five things, stretch these. They are listed in rough order of how much complaining they do.
| Area | Why it tightens when you sit | A stretch that covers it |
|---|---|---|
| Hip flexors | Seated hip is a folded hip | Low Lunge |
| Hamstrings | Slack and unused all day | Seated Hamstring Stretch |
| Lower back | Held rounded for hours | Cat-Cow, Supine Twist |
| Chest and shoulders | Pulled forward by a keyboard | Doorway Chest Stretch |
| Neck | Head held forward of the shoulders | Chin Tuck, Upper Trapezius Stretch |

How long, and how often
This is the part with good evidence behind it, and the answer is smaller than people expect.
A 2025 meta-analysis in Sports Medicine pooled 189 studies covering 6,654 adults to find the dose that actually matters. It reported that thirty-second holds worked as well as sixty-second ones, that gains within a single session flattened at roughly four minutes per muscle group, and that gains across a week flattened at roughly ten minutes per muscle group. Splitting that weekly total across three sessions or six made no difference.
Three things follow:
- Thirty seconds is enough per stretch. A longer hold is not a better hold.
- The weekly total is the number that matters, not any single session.
- Frequency is yours to choose. Three longer sessions and six short ones came out the same.
The same review found the largest improvements in the people who started out the least flexible. If you cannot reach your toes, you are in the group the research says changes most.
We went further into this in how long you should hold a stretch.
Where to start, by what is bothering you
- Lower back tight by mid-afternoon. Start with the hips, not the back. See stretches for a lower back that aches after sitting.
- Hips feel locked when you stand up. See tight hips from sitting all day.
- Neck and shoulders stiff by 4pm. See why your neck hurts at a desk.
- Cannot reach your toes. See why can't I touch my toes.
- No floor, no privacy, no mat. See stretching when there is nowhere to lie down.
- Want it to help you wind down. See stretches before bed.
The habit is the hard part
Nobody struggles with the stretches. People struggle with doing them on a Tuesday in February.
Two things help more than any technique. Keep the session short enough that you never have to negotiate with yourself about starting it. And attach it to something that already happens: the kettle, the end of a meeting, the moment you close the laptop.
A missed day is not a failure state. There is no streak to protect here, and nothing is undone by stopping for a week.
When to stop, and when to ask someone
Stretching is general fitness, not treatment. Stop anything that causes pain, dizziness, numbness or anything that simply feels wrong. Discomfort and pain are not the same thing, and the difference is one only you can judge from the inside.
Talk to a doctor or physiotherapist before starting if you have a joint or back problem, recent surgery, a cardiovascular or neurological condition, or if you are pregnant or recently postpartum. Our fitness and safety note has the full version.
Never force a stretch to reach the shape in an illustration. The figure shows a movement, not a target.
Where Lucy fits
Lucy is an iPhone app of short guided stretching routines for people who sit all day. Sixteen routines, fifty-nine stretches, and nothing in it runs longer than six minutes. A timer counts each hold and tells you when to switch sides, so you are not watching a clock.
Three of the sixteen need no floor at all. Any stretch can be shortened before you start, and it remembers. There is no account, and it works offline.
One routine is free in full rather than as a preview. The rest is a subscription with a 7-day free trial, priced in your own currency on the App Store.
FAQ
How much stretching do you actually need if you sit all day?
The Sports Medicine meta-analysis above found gains levelling off at about ten minutes per muscle group per week, with no advantage to concentrating it or spreading it out. For the five areas that sitting affects, that works out at a handful of minutes most days rather than a long session once a week.
Is stretching or walking better for someone who sits all day?
They solve different problems and neither replaces the other. Standing up changes the joint angle your body has been holding, which is why it helps to do it every forty minutes or so. Stretching takes a joint through range it has not visited. Doing a little of both is more useful than doing a lot of either.
Does a standing desk mean you can skip this?
Standing is a different fixed position rather than an absence of one. It changes which areas take the load, and the hamstrings and calves generally notice. The useful variable is how often you change position, not which position you default to.
Should you stretch before or after sitting all day?
Afterwards tends to be easier to keep up, because the muscles have just spent hours held at one length and because the end of the working day is a more reliable cue than the start of it. The research found no difference from when in the week you accumulate the minutes, so the honest answer is whenever you will actually do it.
Do you need a mat or any equipment?
No. A wall and a doorframe cover most of the upright stretches, and a carpet is fine for the floor ones. Three of Lucy's routines are built entirely from stretches that work standing in about a square metre.
Lucy runs all of this as timed routines, so you are following a voice instead of a page.
