Does exercise help back pain?

What the guidelines say

Exercise appears in the main guidance, but the wording is cautious. The NICE guideline on low back pain (NG59) recommends that people with low back pain get advice to help them manage it themselves, including encouragement to continue normal activities. It also says clinicians should consider an exercise program run for several people at once, using biomechanical, aerobic or mind and body approaches, or a mix, for a specific episode or flare-up. The type should take a person's needs, preferences and abilities into account.

The NHS back pain page tells readers to stay active and continue daily activities, and it names walking, swimming, yoga and pilates as activities that may help ease back pain. It also says to stop if pain gets worse and to see a GP for advice. For the related question of bed rest, see whether to rest or keep moving.

Evidence for long-lasting pain

For pain that has lasted three months or more, the World Health Organization's 2023 guideline says a structured exercise therapy or program may be offered. That is a conditional recommendation based on low-certainty evidence, which means the benefit is likely but the confidence in the size of it is limited. More on that condition is in what chronic low back pain is.

A 2021 Cochrane review pooled 249 trials of exercise for chronic low back pain. It found moderate-certainty evidence that exercise is probably more effective for pain than no treatment, usual care or a placebo. The average difference was about 15 points on a 100-point pain scale, which the reviewers counted as clinically important. For physical function the difference was about 7 points, which did not reach their threshold for an important change.

What limits the evidence

Cochrane's authors say most of the trials were at risk of bias, partly because people cannot be blinded to whether they are exercising. Compared with other conservative treatments taken together, the improvements were small and not clinically important, and no difference was seen against manual therapy such as massage or spinal manipulation. For pain, exercise was probably more effective than education alone. Reported harms were mostly minor, such as muscle soreness.

The Chartered Society of Physiotherapy says exercise has been shown to be the most helpful treatment for back pain and that the type matters less than staying active. The Cochrane review points to a more mixed picture, noting that large, well-designed studies are still needed. What works for one person may not suit another, and these sources describe averages across many people.

Where to learn more

Choosing particular movements is a decision for a clinician who has examined you, so this page does not suggest specific exercises. A physiotherapist usually guides that choice, and what physiotherapy for back pain involves explains the process.

When to get help

The NHS says to see a GP if back pain does not improve after treating it at home for a few weeks, stops you doing everyday activities, is worse at night or after resting, or comes with unexplained weight loss. It advises calling 111 or seeking urgent help for severe pain that starts suddenly or quickly worsens, or for feeling hot, cold, shivery or unwell. Call 999 or go to A&E for pain, tingling, weakness or numbness in both legs, loss of feeling around the genitals or anus, bladder or bowel changes, chest pain, or pain that began after a serious accident.

Services and advice differ between countries and clinicians. Check with a clinician before starting a new exercise routine, particularly if you have other health conditions.
