Chronic Low Back Pain Exercises: What the Evidence Supports

Search for chronic low back pain exercises and you get lists: ten stretches, five core moves, the one exercise a surgeon swears by. The trials point somewhere less exciting. Several kinds of exercise help a bit on average, the largest review could not name one best type, and the one you keep doing and keep progressing is the one that has a chance to work.

I had low back pain for about ten years and tried most of what is on those lists. I have no medical credentials. This page is what the reviews say about each type, and how I would judge whether one is working.

What the guidelines say about exercise

WHO's December 2023 guideline includes exercise within tailored care for chronic primary low back pain. The American College of Physicians 2017 guideline recommends starting with treatments that are not drugs and lists exercise, multidisciplinary rehabilitation, yoga, tai chi and motor control exercise among the first treatments to try.

The 2021 Cochrane review by Hayden and colleagues pooled 249 trials. Compared with no treatment, usual care or placebo, exercise probably reduces pain, by about 15 points on a 100-point scale at the first follow-up. The effect on function was about 7 points, below the authors' threshold for a clinically important change. Compared with other conservative treatments, the differences were small. The review could not recommend one specific type of exercise. Its authors report that their related network meta-analysis found Pilates, McKenzie therapy and functional restoration more effective than other types for pain and function. So exercise has guideline support for chronic low back pain in general, and the average benefit is modest.

The main types, and what the trials found

General strengthening and resistance training

Strength work for the back, hips and legs, usually with load that goes up over time. ACP lists exercise in general among its moderate-quality recommendations. Resistance training sits under the broad exercise category in the Cochrane review. Its main advantage for a home program is that the dose is easy to measure and raise.

Motor control exercise

Training the deep trunk muscles to switch on and coordinate, then building toward harder tasks. Bird-dogs and dead bugs belong here. A Cochrane review of 29 trials (2,431 people) found it helped more than minimal intervention, gave similar results to other forms of exercise, and concluded that the choice of exercise should probably depend on preference, therapist training, cost and safety.

Pilates

A Cochrane review of 10 trials (510 people with chronic non-specific low back pain) found low to moderate quality evidence that Pilates reduces pain and disability compared with minimal intervention, and no conclusive evidence that it is better than other exercise. The authors suggested the choice could rest on preference and cost.

Yoga

The 2022 Cochrane review of yoga (21 trials, 2,223 people) found small improvements in pain and function compared with no exercise, smaller than the authors counted as clinically important, and probably little or no difference from other back-focused exercise for function at three months. Yoga brought more adverse events than no exercise (mostly more back pain), and about the same as other exercise.

Walking

Walking is the easiest exercise to keep up. The WalkBack trial (701 adults who had recently recovered from an episode of low back pain) tested a progressive walking and education program with six physiotherapist sessions over six months. The median time to the next activity-limiting episode was 208 days in the walking group and 112 days in the control group. That trial was about preventing the next episode, not treating long-running pain. The walking and standing page covers the day-to-day side.

McKenzie method

A system of repeated movements or positions, with the direction chosen from how your symptoms respond. A 2006 meta-analysis of 11 trials found a small effect against passive therapy for acute pain, too small to be clinically worthwhile, and limited evidence for chronic pain.

Pick one you will progress and keep doing

Since the evidence does not settle on one type for everyone, the useful questions are practical. Can you do it two or three times a week for months? Can you afford it? Does it have a clear way to get harder? Does it fit around a bad week?

Check whether your home program explains how to progress when the exercises become easier. A list of exercises with set reps gives no instruction for what happens when they get easy. The why PT exercises stop helping page goes into why a plan that never changes tends to plateau. If you are unsure whether you need to stretch or strengthen, see stretching versus strengthening, and if a scan showed a disc finding, see exercise with a disc bulge or degeneration.

I picked back extensions on a 45-degree bench because the dose is easy to measure and easy to raise in small steps: seconds of holding, then range, then reps, then a plate. The are back extensions good for lower back pain page covers that choice in more depth, and the back extension progression page lists every stage.

Dose and progression

Start below what you think you can do. Start with a small dose you can adjust. A flare can interrupt training, and how long it lasts varies.

1. Pick a starting dose you can repeat without a worse morning.
2. Train two or three times a week with a day between sessions.
3. Change one thing at a time: a few more seconds, one more rep, a little more range, or a little more load.
4. Repeat a dose until it feels routine before you raise it.
5. After a break of a week or more, come back a step lower.

With a sore back, small steps and a check the next morning act as a brake on doing too much too soon. The how often page covers weekly frequency.

How to judge it: the next-day response

Pain during a session is a poor guide on its own. Some ache while you train is common and often settles. The more useful reading is the next morning, compared with your usual day.

• Worse than usual: ease the next session.
• About the same: repeat the session, unless the previous training day's next-morning check-in was also at or below your usual, and neither was higher than the pain you logged before that session. Then take the small step up.
• Better than usual: take a small step up.

This is a pacing rule, not a diagnostic test. It tells you whether to go up or down, and it cannot tell you what is wrong. Pain in your legs, or pain spreading that way during an exercise, means stop that exercise and do not add load. The hurt versus harm page explains why soreness after training usually is not damage.

Give a program long enough to judge. Pain tends to change more slowly than strength, and the how long it lasts page has the timelines. Track what you can do as well as the pain score.

The bench program in Low Back Pain Coach uses this next-morning rule, and this exact progression has not been tested in a trial. The research above supports exercise for chronic low back pain in general.

Low Back Pain Coach is the app I built for this. It runs guided sessions on a 45-degree back-extension bench, and your next-morning pain log sets the next session. The bench is required. The first session is free, then it costs $59.99 a year or $9.99 a month, with a 7-day free trial for eligible new subscribers. The app page has the details.

Before you start

Go to emergency care now for new numbness, tingling or change in feeling in the saddle area (groin, inner thighs, genitals or anus), new changes in sexual function, new bladder or bowel changes, new pain, tingling, numbness or weakness in both legs, leg or foot weakness that is getting worse, or back pain after a recent serious accident. See a clinician today (urgent care if you cannot get an appointment today) for other new weakness or numbness in one leg or foot, fever or chills with the back pain, new pain after a recent smaller fall or knock, unexplained weight loss or a history of cancer, pain that is rapidly getting worse, or pain that is constant at rest and worse at night, not tied to movement. The red-flag checklist has the full list.

If you have not been examined for your back pain, or it has changed recently, see a doctor or physical therapist before starting a new program. The appointment questions page has what to ask.
