Chair Lower Back Stretch
Also works: Lower Back
A seated side bend: sit upright, reach one arm over your head and lean away from it while the other hand anchors the chair. Sitting locks the pelvis down, so the bend has to come from the spine and ribcage rather than the hip — which is what puts the lat and the side of the trunk under real tension.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Sit upright on a chair with both feet flat on the floor and your weight even on both sit bones.
- Grip the seat or the frame with the hand on the side you are bending toward — that anchor is what stops your hips lifting.
- Raise the opposite arm straight overhead, biceps close to your ear.
- Set your ribs down over your pelvis before you lean, so you start from neutral rather than an arched back.
Every rep
Breathing & tempo — Breathe into the stretched side deliberately: feel the ribs expand under the overhead arm on each inhale, and lean a fraction further on each exhale.
How much, how often
Where to start, and what to change when it stops being hard.
No load. Two or three holds of 10-20 seconds per side, repeated whenever you have been sitting for an hour. Frequency is the variable that matters here — six short doses across a day do more for a stiff flank than one three-minute session.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Push the far sit bone down into the seat and pull on the chair frame with the low hand. Half the range with both hips planted is more stretch than a full lean that takes the pelvis with it.
Imagine you are sliding between two panes of glass. Keep the sternum pointing forwards and the overhead elbow in line with your ear the whole way.
Drop the raised shoulder away from your ear before you lean, and initiate the bend from the ribs. The stretch should be felt down the flank, not in the upper trap.
Sit on the front third of the seat with nothing behind your spine, feet flat and hips level. A backrest lets your ribs settle behind your pelvis, and the bend then happens through a slumped lumbar spine rather than the flank you were aiming for.
Why bother
Standing side bends leak: the pelvis drifts sideways and takes most of the range, so the spine barely moves. Sitting on a chair pins your hips in place. Every degree of lean has to come from the ribcage and lumbar spine, which is why a seated version of the same movement feels twice as strong on half the travel.
The overhead arm is what recruits the lat. The latissimus runs from the upper arm to the pelvis and lower spine, so shoulder flexion plus side bend away from that arm lengthens it across both ends at once. Leave the arm down and you get a quadratus lumborum stretch instead — useful, but a different target.
Where it fits
It costs ten seconds and needs only the chair you are already sitting in, which makes it a desk-break stretch first and a training stretch second. Two or three holds per side, several times through a working day. It is also a reasonable thing to do between sets of heavy pulling, when the lats have been working hard.

Asked and answered
Will this fix lower back pain from sitting all day?
It will give short-term relief, and that is worth having. It will not fix the cause, which is usually the hours of static position rather than any short muscle. Standing up every half hour and getting the hips moving does more than any single stretch. Use this as the thing you do at the desk, not as the plan.
Should I feel this in my back or my side?
Down the side — the flank, the lower ribs, and along the lat under the raised arm. A central lumbar sensation usually means you are arching backwards as you lean. Set the ribs down over the pelvis, keep the bend purely sideways, and it will move out to the side where it belongs.
Can I do this standing instead?
You can, but you will get less out of it. Standing lets the pelvis slide sideways and absorb most of the range, so the spine bends far less than the picture suggests. If you have no chair, stand with your feet together and press the hip on the anchored side firmly down and in.
How often is too often?
There is no meaningful upper limit at these durations — it is bodyweight side bending in a chair. Several times an hour is fine if it feels good. The only thing worth watching is doing it always to the same side, which reinforces an asymmetry rather than easing one.
