Why does sitting hurt my lower back?

Long periods of sitting load the lower back, shorten the hip flexors and let the glutes and core switch off, which together can leave the back stiff and achy. Breaking up sitting with movement and gentle mobility helps.

How often should I move at a desk?

A short movement break every hour or two of sitting is a good target. Even standing and moving for a couple of minutes helps; a quick mobility reset like this undoes more of the stiffness.

Will this fix back pain from sitting?

It can ease the everyday stiffness sitting causes, but lasting change also needs more movement overall and better sitting habits. Persistent or severe pain is worth seeing a clinician about.

Desk-back reset

A short routine to undo the stiffness a day of sitting builds into your lower back — gentle pelvic tilts and bridges to wake the area, spinal movement, a lying twist and a calm finish. The app names each move and times every hold, so you can reset between work blocks or at the end of the day. The bookmarked answer to a back that's seized up at the desk.

How the session works

1Find a bit of floor space and lay out a mat.
2Press start. The app names each move, cues it gently, and counts each hold down.
3Move slowly and keep it pain-free; the goal is to undo stiffness, not to push.
4Run it once at the 5 or 8-minute length whenever sitting has left you stiff.

What it's good for

Targets the lower-back stiffness that builds from prolonged sitting.
Wakes the glutes and core that switch off at a desk, gently.
Short enough to fit between meetings or after a workday.

The evidence. Prolonged sitting is a common contributor to low-back stiffness; regularly interrupting it with gentle movement is well supported for easing discomfort, and complements moving more across the day.

Safety

See a doctor urgently — do not use this — if you have numbness in the groin or saddle area, loss of bladder or bowel control, leg weakness or a dragging foot, back pain after a fall or accident, or pain with fever, unexplained weight loss, or that is severe and worse at night. These need urgent care, not stretching.
These gentle moves are for everyday stiffness, not a new or severe injury — if your pain is new, severe, follows a specific injury, or you're pregnant or have a known disc or nerve condition, see a clinician first.
Stay in a small, pain-free range and stop any move that sharpens the pain or sends pain, numbness or tingling down a leg.
