Short answer: regular exercise beside medical treatment, not instead of it
Regular exercise is a core part of managing axial spondyloarthritis (of which ankylosing spondylitis is one type), but it works beside medical treatment, not instead of it [1][11]. It means movement, stretching, good posture, deep breathing, strengthening and gentle endurance work such as walking or swimming, at an amount that suits your current disease activity [1][4]. Exercise can ease pain and improve movement and function a little, but it does not cure the condition, because there is no known cure today [3][11][15].
The questions people ask most about this topic, with short answers: • Can it be cured? No. There is no cure, but treatment and exercise control symptoms and may help delay the spine fusing [11][12][15]. • What is biologic treatment? A group of medicines prescribed when anti-inflammatory tablets are not enough and there is evidence of active inflammation. The decision belongs to the treating doctor [1][11]. • What is the fastest treatment for lumbar inflammation? First confirm that the pain really is inflammatory. After that, anti-inflammatory tablets are the first-choice medicine in the guidelines, together with movement [1][12]. • What causes it? The exact cause is not known, but genes play a big part [13][15].
The details are in the next sections. If you are still trying to tell inflammatory back pain from mechanical back pain, see our dedicated article on it, since we do not repeat the symptoms here.
Exercise and medicine: each has a different job
The NHS describes treatment as exercise, physiotherapy and medicine together, not any one of them alone [11]. The 2022 recommendations from the two international societies place non-drug management, including exercise, among the first recommendations, alongside anti-inflammatory tablets as the first-choice medicine [1]. European recommendations from 2018 also say physical activity is an integral part of standard care in inflammatory arthritis [5]. In the large review of exercise trials, most programmes were delivered alongside drug or biologic therapy, so exercise was an addition, not a replacement [3].
Where do biologic medicines fit? According to the recommendations, they are considered when the disease is active, at least two anti-inflammatory tablets did not give enough relief, and there is objective evidence of inflammation, such as a raised inflammation blood test, inflammation on sacroiliac joint MRI, or changes on X-ray [1]. The types listed are inhibitors of tumour necrosis factor, inhibitors of another inflammatory protein called interleukin-17, or targeted oral medicines [1]. In the UK, anti-tumour necrosis factor drugs are given by injection and are reviewed if there is no clear improvement after at least 3 months [11]. American recommendations from 2019 favour tumour necrosis factor inhibitors over interleukin-17 inhibitors as the first biologic [2].
All of this is general description. Doses, the choice of medicine and when treatment changes are decisions for the doctor who follows you. This article gives no medicine advice, and no exercise replaces monitoring disease activity with tests and examination [1].
What do the studies say about exercise?
• The 2019 Cochrane review pooled 14 randomised trials with 1579 participants, with a median programme length of 12 weeks. Compared with no intervention, the pain score fell by 2.1 points (6 studies, 288 participants), the function score by 1.3 points and the disease-activity score by 0.9 points [3]. • The same review concluded that exercise probably improves function slightly, may reduce pain, and probably reduces overall disease activity slightly. Evidence quality ranged from moderate to very low, and safety is not fully settled because few adverse events were recorded [3]. • A 2025 analysis of 20 trials with 1670 patients found exercise improved the function score by 0.49 points, the spinal mobility score by 0.49, and the disease-activity scores by 0.78 (Bath activity index) and 0.44 (ASDAS), and also improved fitness (peak oxygen uptake and 6-minute walk distance) [7]. • A randomised trial of 100 patients (97 completed) used supervised high-intensity exercise for 3 months. Disease activity fell by 0.6 on the ASDAS scale and 1.2 on the Bath activity index, and the difference was statistically significant. This eases the worry that vigorous exercise raises disease activity, but it is the result of a supervised trial, not an invitation to start hard training alone [6]. • A 2016 expert consensus using a modified Delphi method covered 10 questions, from assessment, monitoring and safety to exercise dose and setting [4].
The overall picture: the benefit is real but moderate in size, and the evidence is not the strongest, which is why your programme should be set according to your condition with your doctor or a physiotherapist, not as a ready-made recipe [3][4].
The types of exercise that recur in the guidance
The guidance talks about types of exercise, not one recipe that suits everyone. The description here is educational only, and a specific programme is set with a physiotherapist who assesses your condition [4][11]: • Mobility and flexibility: gentle, regular stretching of the spine, shoulders and hips to keep the range of movement. The NHS says regular activity improves posture and the range of spinal movement [11]. • Posture work: exercises that encourage lengthening of the spine, neck and chest, the opposite of the spine stiffening in a forward-bent position [14]. • Breathing and chest expansion: when the rib joints are affected, taking a deep breath can become difficult, so deep-breathing exercises help keep the rib cage moving, and chest expansion is measured in the studies [7][15]. • Strengthening: work for the back, abdominal, hip and shoulder muscles to support the spine and hold posture [4][7]. • Endurance for heart and lungs: brisk walking, cycling or swimming at moderate effort. In the newest analysis, fitness improved in people who exercised regularly [7]. Swimming and other sports are usually fine, alongside daily stretching [11].
You do not need every type on the same day. What matters is regularity: the programmes pooled in the review had a median length of 12 weeks [3]. Before starting a new sport, check with your rheumatologist or physiotherapist [11]. For a general comparison of sports in joint pain, see our article on exercise for joint pain.

Posture habits in daily life: sleeping, sitting and standing
Posture is not only exercises, it is also daily habits. The practical reason: fusion of the spine can fix posture in one shape, so the aim is to keep the joints moving as much as possible before that happens [14]. Pain from the condition often worsens with long rest, continuous sitting and at night, and movement usually eases it [15]. The ideas below are general and not the result of comparative trials, so keep them flexible to your comfort, and let your doctor or physiotherapist set personal details such as mattress, pillow and sitting position: • Sleeping and mornings: gentle movement and stretching as soon as you get up loosens stiffness [15], and try not to stay curled forward for long periods. • Sitting: stand up and walk at short intervals instead of sitting for hours, because continuous sitting tends to worsen the pain [15]. • Standing and walking: change position and move at intervals instead of holding one position for long [15]. • Work and driving: take short movement breaks. This is practical organisation, not a recommendation from a study. • Carrying: spread the load across the body and avoid sudden heavy lifting from a bent position, especially if bones are weak [14].
You do not need to be "perfect" all the time. Changing position often matters more than holding a "correct" position for hours.
During a flare: adjusting exercise without stopping altogether
The disease runs in flares and quieter periods, meaning periods when symptoms increase and periods when they ease [15]. Since pain and stiffness usually worsen with rest, stopping movement completely is often not the answer [15]. A reasonable adjustment during a flare: • Lower the intensity and length: gentle stretching and range-of-motion work instead of strenuous exercise, and split the session into short blocks. • Choose gentler movement: swimming or water exercise is easier on the joints, which is why hydrotherapy is part of physiotherapy programmes [11]. • Do not push through pain: sharp pain, or pain that clearly rises after exercise, is a signal to reduce, not to carry on. If pain lasts days after a particular exercise, reduce or change the movement and tell your doctor. • Keep a flare log: when it started, what made it worse and what eased it. This helps the doctor judge disease activity. • If flares are frequent or do not settle with rest and adjustment, that is a reason to re-evaluate the treatment plan medically, since the recommendations say treatment failure should prompt re-evaluation [1]. Do not change any medicine yourself.
In every case, some movements are worth asking about before you do them, especially with long-standing disease or bone thinning: contact and collision sports, high-impact jumping, forceful trunk twisting and sudden heavy lifting [11][14]. The reason is that a stiffened spine is more prone to fracture, even after a minor injury [8].
Red flags: spinal fracture and symptoms you should not wait on
A stiffened spine breaks more easily, even after minor trauma. Fracture pain can be wrongly put down to disease activity, ordinary X-rays can miss it, and MRI or CT are more accurate [8]. In an analysis of 22 studies, the odds of vertebral fracture were roughly double those of other people (ratio 1.96), while other bone fractures rose only slightly (1.10) [9]. A newer analysis of 39 studies found that risk factors were older age, longer disease course and low lumbar bone density, and that osteoporosis and fracture risk is higher in younger patients and in the early stage [10]. The NHS also says the risk grows the longer you have the condition [14].
Seek prompt medical assessment if: • You get new, sudden, severe back or neck pain after a fall, an accident or even a small movement, especially if it differs from your usual pain [8]. • Pain gets worse with movement instead of easing, or comes with new weakness or numbness in the legs [15][14]. • You have a red, painful eye that is sensitive to light: this may be inflammation inside the eye (iritis) and needs a doctor promptly [14].
Very rarely, pressure on the nerves at the lower end of the spinal cord (cauda equina syndrome) causes sciatica on both sides, severe or worsening weakness or numbness in both legs, numbness around the genitals or anus, and bladder or bowel control problems. This is an emergency, so go to the nearest emergency department immediately [14].
Bone density scanning (DEXA) is done outside our clinic. To learn who needs one, see our article on osteoporosis.
The cause, and the fastest treatment for inflammatory low back pain
What is the cause? It is not known exactly. A genetic variant known to doctors is linked to the condition, and more than 8 in 10 patients carry it, but about 8 in 100 of the general population carry it and most never develop the disease, so the gene alone is not enough [13]. There may be environmental factors that are still unknown, and the condition can run in families [13]. Known risk factors include family history, onset usually before age 45, and having Crohn's disease, ulcerative colitis or psoriasis [15]. Most cases start in the teens and young adulthood [12].
What is the fastest treatment for lumbar inflammation? There is no single "fastest" treatment that suits everyone, because low back pain has many causes. The logical steps: • Confirm the pain is truly inflammatory and not mechanical, because treatment differs; the signs that separate them are in our dedicated article. • For confirmed inflammatory pain, anti-inflammatory tablets are the first-choice medicine in the guidelines, with the doctor's assessment and follow-up and no doses from us [1][12]. • Movement and stretching complement the medicine; they do not compete with it [11][15]. • If that is not enough, the doctor considers other options such as biologics after assessment [1][11]. • Do not treat it with bed rest, because inflammatory pain usually worsens with rest [15].
If the pain is mechanical (worse with movement and eased by rest), the picture is different, and the causes of joint and spine pain are wide, so see our article on the causes of joint pain and when to see a rheumatologist.

When to book with our rheumatologist
Book a rheumatology assessment if: • You have back pain that began before age 45, persists, and worsens at night or in the morning with stiffness that eases with movement [15]. • You are diagnosed and want to know which exercises suit your stage, or you have frequent flares [1][4]. • You have back pain after a minor fall or a new, different pain, once you have made sure it is not an emergency [8]. • You have inflammatory bowel disease or psoriasis together with back pain [15].
The clinic assesses disease activity and coordinates drug treatment; physiotherapy is delivered outside the clinic, and where needed we refer you to a suitable specialist. Our rheumatologist is Dr Shimaa Sherif, in the Maadi branch (14 El-Mokhtar Street, behind QNB, New Maadi) and the Fifth Settlement branch (CMC Medical Mall, 4th floor, North 90th Street, Wednesdays from 3:30 pm).
