A sweeping analysis of exercise research, published in February 2026 in the British Journal of Sports Medicine, found that structured exercise reduced symptoms of depression and anxiety about as well as, and in some cases better than, antidepressants and talk therapy. The umbrella review pooled 81 meta-analyses covering more than 1,000 individual studies and 79,551 participants.
One type stood out. Aerobic activity, meaning movement that raises the heart rate and breathing such as brisk walking, running, cycling, swimming or dancing, showed the strongest impact on both depression and anxiety symptoms. Sessions of roughly 30 to 45 minutes, three to five times a week, were described as the sweet spot in press coverage of the review.
What the numbers show
Across the pooled data, exercise produced a medium-sized reduction in depression symptoms and a small-to-medium reduction in anxiety symptoms, according to the study abstract. The authors, led by Neil Richard Munro of James Cook University in Queensland, Australia, concluded that exercise-based interventions in all formats can help ease symptoms across age groups and populations.
For depression, aerobic training in supervised or group settings delivered the largest benefits, a finding the researchers linked to the social component of working out together. For anxiety, shorter programs of up to eight weeks and lower-intensity movement appeared most helpful, with aerobic, resistance, mind-body and mixed formats all showing positive effects.

Who benefits the most
The strongest improvements showed up in young adults aged 18 to 30 and in postpartum women, two groups where mood disorders are common and where medication is often complicated by side effects or, in the case of new mothers, by concerns around breastfeeding. Benefits were consistent across other age groups and both sexes.
The depression analysis alone covered 57,930 participants aged 10 to 90, while the anxiety analysis included 19,368 participants aged 18 to 67. Effect sizes were expressed as standardized mean differences of -0.61 for depression and -0.47 for anxiety, values that fall into the medium range in psychological research.
What the review does not say
The findings do not mean anyone should stop taking prescribed antidepressants.
The review pooled trials that used exercise as a treatment, but it did not run head-to-head comparisons against specific medications, and independent experts have flagged that most of the included meta-analyses were rated low or critically low in quality, as summarized in expert reactions collected by the Science Media Centre.

Anyone currently on medication for depression or anxiety who wants to add or shift to exercise should talk to their doctor first.
Motivation is also a real barrier, something the researchers themselves acknowledged: severe depression can sap the very energy needed to lace up a pair of running shoes.
Still, the direction of the evidence is consistent. Move regularly, preferably with other people, ideally at an aerobic intensity that leaves you a little out of breath.
On the mental health ledger, that pattern keeps showing up as one of the strongest non-drug interventions science has to offer.
