Walking is the intervention with the clearest recent trial evidence for preventing back pain from coming back, and it is close to free. The WalkBack randomised controlled trial, published in The Lancet in 2024, was the first trial to test a walking programme for recurrence prevention.1
The trial
Adults who had recovered from an episode of non-specific low back pain within the previous six months were randomised to an individualised, progressive walking programme with education, or to no intervention. Recruitment ran through 25 physiotherapy clinics in Australia.
| Outcome | Result |
|---|---|
| Risk of activity-limiting recurrence | 28% lower |
| Median days to recurrence | 208 vs 112 |
| Cost-effectiveness | Favourable |
A secondary analysis also reported effects on the duration and severity of the recurrences that did happen, not only on whether they happened.2
An individualised, progressive walking and education programme nearly doubled the median time before the next episode of activity-limiting back pain.1
Why walking and not something more specific
The 2018 Lancet series on low back pain had already concluded that exercise, with or without education, is the only intervention with reasonable evidence for preventing episodes.3 What WalkBack added was that the exercise does not need to be specialised, supervised in a gym, or targeted at any particular muscle. It needs to be progressive and sustained.
That matters because adherence is where most programmes fail. Walking has the lowest barrier of any intervention on this site: no equipment, no venue, no skill.
What “progressive” means here
The trial did not prescribe a fixed dose. Participants started from their own baseline and built up, with a physiotherapist adjusting the target. The practical translation:
- Start from what you currently do, not from a target you read somewhere.
- Add time before you add intensity.
- Increase gradually and keep going during minor flare-ups rather than stopping.
- Aim for most days, not for a heroic weekly session.
What it does not do
This is prevention of recurrence in people who have recovered. It is not a treatment for an acute episode, and it is not a substitute for assessment if you have red-flag symptoms.
How you walk matters less than walking
There is no special technique to learn. A relaxed, upright walk with your eyes ahead is enough, see walking posture. The one habit worth changing is walking head down over a phone, which slows you, stiffens the neck and adds risk near traffic, see walking while using your phone.
For a daily target, how many steps you actually need explains why your own baseline is a better starting point than 10,000. Walks also make good breaks from sitting, see how often to take sitting breaks.
