Eight hours at a laptop takes mobility out of the thoracic spine and the front of the hip first, and the part that aches by evening is usually the lower back. The working minimum is unglamorous: two or three minutes at your chair every ninety minutes, plus ten minutes on a mat in the evening. Thoracic extension and hip opening do more than stretching the lower back itself. Strength work then keeps what you got back.
Why a Dubai desk job compounds this faster
Desk work is the same everywhere. The day built around it here leaves almost no movement in it.
Morning: lift to the basement car park, car, office tower car park, lift again. Lunch on the same level. The same route home. Many of my clients do not step outside once between leaving home and getting back. The city is built that way, and it has nothing to do with willpower.
From May through September the heat adds its own layer. The evening walk cancels itself: it is still past thirty degrees at eight in the evening. Anyone who had a post-work walking habit loses it for four or five months, and it does not always come back.
Air conditioning works separately. Offices here run cold, people sit in a jacket or with a scarf on, and cold shoulders creep up towards the ears. I can see it in how a client walks into the gym in September: shoulders forward, head slightly ahead of the body. Four months of cold air and a laptop made that the default position.
On a first session I ask people to open last week's step count on their phone. Someone with a car and a basement parking spot usually has two or three thousand a day, and the number is almost always a surprise, because the day felt busy. The WHO 2020 physical activity guidelines make a separate point of telling adults to limit sedentary time and replace it with activity of any intensity (the guideline). That is a reference point rather than a prescription for everybody, but it sets the direction honestly.
Then there are flights. Dubai sits five to eight hours from half the world, and a week with two long-haul legs is routine for a lot of my clients. That is another sixteen hours in a seat on top of the working ones.
What actually tightens
Sitting holds the body in one shape: thoracic spine rounded, shoulders forward, hip bent at ninety degrees, glute doing nothing at all.
The thoracic spine stops extending and rotating. That matters less on its own and more because part of your overhead reach and almost all of your trunk rotation pass through it.
The hip flexor spends the day in a shortened position. When you stand up it does not get back to its usual length straight away, and the pelvis stays tipped slightly forward.
The glute is switched off literally, since you are sitting on it. After years of that schedule it stops firing on time even in walking, and certainly on stairs.
The lower back pays for its neighbours. It is moderately mobile and its job is to hold rather than twist. When the thoracic spine will not rotate and the pelvis will not extend, the lower back takes their work on. The ache lands there, the cause sits above and below it.
The checks I start with
Four tests, twenty seconds each. We use the same four later to see whether anything moved.
- Arms overhead against a wall. Stand with your back to the wall, feet ten centimetres out, lower back pressed flat. Raise straight arms and try to touch the wall with the backs of your hands without letting the lower back lift off. With desk clients the arms either do not reach, or they reach at the cost of the lower back arching forward.
- Seated rotation. Sit on a chair, knees together, arms crossed on your chest, rotate as far as you go. If the rotation happens because one knee slides forward, the thoracic spine is not part of it.
- Supported lunge. Drop into a lunge with the back knee on the floor and tuck the pelvis under you, taking the arch out of the lower back. If the front of the back thigh lights up in the first second, the hip flexor is short.
- Full squat. Squat all the way down with heels on the floor, arms forward. If the heels lift or you fall backwards, this is about strength in that position as well as mobility.
Film all four from the side on your phone. A mirror lies, video does not.
Shoulders and thoracic spine
I rarely work on the shoulder itself. When the thoracic spine is locked, the arm goes overhead by arching the lower back instead, and people live with that for years until they pick up a racket or press a dumbbell overhead.
What works at the desk, in a shirt:
- Extension over the chair back. Sit so the chair back sits in the middle of your back, below the shoulder blades. Hands behind your head, elbows forward, exhale and arch back over the chair. Eight reps, no bouncing, pelvis still. It should be felt between the shoulder blades, not in the lower back.
- Seated rotation drill. Knees together with a folder squeezed between them so the pelvis cannot help. Arms crossed on the chest, rotate to the end of range, hold two seconds on the exhale. Eight each side.
- Wall slide. Back to the wall, lower back flat, forearms and the backs of your hands touching the wall, slide the arms up. Ten reps. The moment the lower back leaves the wall, today's range is over. It is a drill and a test at once.
In the evening the open book joins in: lie on your side, knees bent and resting on a support, let the top arm carry the ribcage back towards the floor. Eight to ten each side, exhale at the end of range. The aim is feeling the rotation between the shoulder blades, not touching the floor.
In the gym this gets pulling added to it: rows, lat pulldowns, pull-ups. Range without strength in it does not get used under load, because the body does not treat it as its own.
Half of my desk clients play padel on a Saturday, and they all arrive with the same complaint about the shoulder after a match. What is actually locked is the thoracic spine after five days at a laptop. How that gets handled for the game specifically is written up in the piece on mobility and strength for padel.
Hips and pelvis
This is where most of the evening lower-back ache comes from, and the part people skip.
- Supported lunge with a pelvic tuck. Back knee on the floor or a mat, pelvis tucked, glute of the back leg switched on. Thirty to forty seconds each side, two rounds. There should be tension down the front of the back thigh and no pain.
- The 90/90 position. Sit on the floor with one leg in front bent at a right angle and the other out to the side at a right angle. Switch sides by rotating the hips without pushing with your hands. Eight to ten switches. It looks ugly for everyone in the first weeks.
- Two-leg bridge. Twelve reps, two-second hold at the top, effort in the glute. If you finish the top of the bridge by arching the lower back, go lower and do fewer.
- Supported deep squat. Holding a door frame or a rack, sit all the way down with heels on the floor. Three rounds of twenty to thirty seconds. This is a position most people have not been in for months.
Only the lunge survives in the office: a step back by the wall, tuck the pelvis, twenty seconds a leg. It works in a suit and takes a minute. The second thing I ask for is one or two flights of stairs instead of the lift, not as cardio but so the glute remembers it exists.
The lower back: what to do and what to leave alone
Lower-back mobility is not the goal. When someone asks how to loosen their back, they usually mean the lower back, and what it normally needs is more support from its neighbours rather than more movement.
What I do not hand out straight after a work day: forward bends with a rounded back, and fast twists. That rounded position is the one you have not left all day, so adding it at the end of the day makes little sense. On the habit of cracking your own back when it pulls: the relief is short and the cause stays exactly where it was.
What works:
- Cat-cow with a small range. Eight to ten slow cycles with the breath. Do not squeeze the end ranges.
- Dead bug. Lie on your back, lower back pressed to the floor, lower the opposite arm and leg. Six to eight reps a side. One job only: the lower back stays down. The moment it lifts, shorten the range.
- Side plank from the knee. Twenty to thirty seconds a side. The trunk holds sideways rather than arching.
- Walking. Ten to fifteen minutes at any point in the day. The most underrated thing for a lower back, and the first thing a Dubai day drops.
Now the edge of my job. If it hurts every day, if the pain runs down a leg, if a foot goes numb, if pain wakes you at night or lasts more than two weeks, that is a doctor's question, not a trainer's. I do not diagnose and I do not prescribe treatment. Once a doctor has looked and set the boundaries, I build inside them: what does not hurt keeps getting loaded, the problem area gets worked in a pain-free range. Pushing through pain in a mobility drill is never the point. This is not the part of training where it is supposed to be hard.
Fitting it into a working day
The drills are not the hard part. "I will do it when I remember" works for nobody. So I ask people to attach mobility to something already in the day: after the second coffee, before lunch, after the last call.
| Format | Time it takes | What it actually covers | What it does not do |
|---|---|---|---|
| At the chair between meetings | 2-3 minutes, 3-4 times a day | Thoracic spine, rotation, shoulders | Floor work for hips, and strength |
| Evening mat session | 10-12 minutes, 4-5 days a week | Hip opening, trunk control, thoracic spine | Load, which is what makes range stick |
| Warm-up inside a strength session | 8-10 minutes, 2-3 times a week | Range plus strength in that range | Frequency: twice a week is thin against five desk days |
| Session with a coach | One meeting plus your own work between | Technique correction and selection for your history | Anything, without your three minutes at the desk |
The table reads one way only: the office two minutes and the evening ten add to each other rather than replace each other. ACSM recommends flexibility work on two to three days a week for adults, holding a static position for ten to thirty seconds. That is the common reference point to lean on when it is unclear how long to hold a stretch.
Sleep sits next to the drills in this plan. The American Academy of Sleep Medicine reference for adults is seven hours or more. Someone sleeping five and sitting nine straightens up in sections in the morning no matter how many open books they did the night before.
How to tell whether it is working
After three or four weeks go back to the same four tests and film them again. Something moved if:
- the arms reach the wall and the lower back stays flat while they do;
- seated rotation is wider without a knee sliding forward;
- in the lunge the front of the back thigh no longer lights up in the first second;
- the full squat holds for twenty seconds with heels down;
- you catch yourself sliding down in the chair less often after lunch.
I am not going to promise that the ache is gone by the end of the month, and I will not put numbers on something that cannot be promised. Clients usually notice something else first: they stop thinking about their back in the afternoon, and only later do the tests show a difference. For some that is three weeks, for others a quarter, and it depends mostly on how many hours a day they still spend sitting rather than on the exercise list.
When a coach is worth it, and what they see on video
A YouTube routine genuinely works for some people, and I am not going to pretend mobility cannot come back without a coach. The drills are much the same everywhere. The difference is that a video cannot see how you do them.
The most common picture: someone runs a wall slide while the lower back lifts a couple of centimetres off the wall, which turns the drill into the exact thing we are trying to get away from. Second most common: a bridge finished by arching the lower back instead of squeezing the glute. The person is following the instructions honestly and does feel the work, just not where it was meant to be.
Since 2018, across more than five hundred clients, I have ended up with a short list of compensations that repeat in almost every desk worker, and on a first session I look for those rather than for a pretty range of motion. In one-to-one training it is simpler, because I can put a hand where the person cannot feel anything and the difference lands immediately. Clients who work with me online send video from two angles, side and front, and log in their account what their back did by the end of the day.
If you play on a Saturday, mobility also works as your entry ticket to the match: the state of your thoracic spine after a working week decides what you lift your arm with overhead. That is a separate piece of work and it lives in sport-specific strength.
