What the guidelines sayStrong evidence
EULAR rated aerobic and strengthening exercise "Strong for", with 100% of its experts agreeing. It rated meditative movement (qigong, yoga and tai chi) and mindfulness-based stress reduction "Weak for", with 71% to 73% agreeing, and found too little evidence to recommend yoga, tai chi or qigong on their own. Its patient version says these practices can help sleep and tiredness.
NICE says to offer a supervised group exercise programme for chronic primary pain, which includes fibromyalgia, and names no type: benefits were consistent whether programmes were "cardiovascular, mind-body, strength, or a combination". The NHS says the type of exercise "should be something you enjoy and can continue doing long-term".

Sleep, tiredness, mood and quality of lifeEmerging evidence
In the review behind EULAR's rating (7 trials, 362 people), meditative movement improved sleep, tiredness, low mood and quality of life by moderate amounts compared with control groups, and the sleep and quality of life gains were still there a median of 4.5 months later.
Newer reviews are less certain. In 23 trials of mindful movement (1,734 people), most measures improved but sleep quality and overall quality of life didn't, at very low certainty. In 21 trials of mind-body exercise (1,155 people), overall symptoms, pain and sleep improved, with tai chi helping most broadly and programmes of more than 40 hours doing better. So yoga may help sleep, rather than being sure to.

Pain: may ease a little, on very low quality evidenceMixed evidence
Meditative movement as a whole didn't reduce pain clearly in the 2013 review, though the yoga trials on their own did. A 2025 review of the 3 yoga-only trials (116 women) found all of them favoured yoga on overall fibromyalgia symptoms. But in a 2026 trial of 64 women, 8 weeks of online mindfulness-based yoga eased tiredness, anxiety and overall symptoms more than walking and physiotherapy, and not pain intensity.
Cochrane's review of mind and body therapies (61 trials) rated the pain benefit of movement therapies very low quality and called their effectiveness "unclear". So yoga may ease pain a little, but it isn't a proven pain treatment.

The Oregon trial: 53 women, against a waiting listEmerging evidence
The trial reports bigger improvements with 8 weeks of yoga than on the waiting list in overall symptoms, pain, tiredness, stiffness, mood and catastrophising (expecting the worst about pain). Poor sleep only showed a trend, and tender points didn't change. 91% of the yoga group finished.
Women who finished the yoga programme improved by 31% on the fibromyalgia impact score, a 0 to 100 measure of how much the condition affects daily life (the smallest change people notice is about 14%), and their pain score fell by about a quarter. These are the yoga group's own changes: we couldn't check the size of the difference from the waiting list, because the results tables weren't in the version we could read.
Once the waiting-list group had the programme, it improved as much, and most of the gain held 3 months later. There was no comparison with another exercise, and people knew which group they were in.

Compared with other exercise: no clear winnerMixed evidence
Across 167 trials, every type of exercise except stretching on its own eased pain and low mood. A 2026 network analysis of 8 exercise types ranked swimming, a qigong breathing practice and walking first on different measures, and yoga first on none. The largest trial of yoga against structured exercise, in 256 US veterans, has published only its design, not its results.

Stretching on its ownMixed evidence
In a review of 12 trials (743 people), flexibility training alone gave no clinically important benefit compared with aerobic training, at very low certainty, and it was the only type of exercise that didn't ease pain in the larger review. If you choose yoga, add walking or other gentle cardio and a little strength work.

Tai chi has the largest trialsEmerging evidence
In 226 adults, tai chi did a little better than aerobic exercise on overall symptoms at 24 weeks, and clearly better at the same dose (twice a week for 24 weeks); 24 weeks beat 12, and twice a week was no better than once. In an earlier trial of 66 adults, 60 minutes twice a week for 12 weeks beat wellness education and stretching. The larger trial had no serious side effects.

Newer small trialsMixed evidence
Weekly online yoga for 4 weeks (31 people) improved pain, sleep and pain sensitivity scores compared with no yoga, with no side effects; yoga added to aerobic exercise beat aerobic exercise alone or with strength work in 60 women; and 4 weeks of "medical yoga" improved pain against a waiting list. All were small, single-centre trials read as summaries.
