A major evidence review in the British Journal of Sports Medicine reports that structured exercise can meaningfully reduce symptoms of depression and anxiety, often performing as well as established treatments. The authors assessed a large body of randomized trial data to compare different exercise types, intensities and settings.
The umbrella review combined results from dozens of prior meta-analyses, covering hundreds of individual trials and tens of thousands of participants across a wide age range. Overall, the synthesis found a medium-sized improvement in depression symptoms and a small-to-medium improvement in anxiety.
Which workouts seemed most effective
Aerobic exercise such as running, swimming and dance stood out for depression, particularly when sessions were supervised or done in groups. For anxiety, shorter programs lasting up to about 8 weeks and using lower-intensity activity appeared to deliver the most consistent benefits.
Researchers also found improvements across resistance training and mind-body approaches such as yoga, tai chi and qigong, as well as mixed programs that combine formats. Effects were observed regardless of sex, suggesting exercise can be broadly useful, even if the best “fit” varies by person.
Who benefited most in the data
The strongest reductions were reported among young adults ages 18 to 30 and among women after giving birth, groups that also face elevated risks of mood and anxiety symptoms. The authors note that social and practical factors, including support and accountability, may help explain why group formats performed well.
While the results were generally comparable to medication or talking therapies, the study does not argue that exercise should replace clinical care for everyone. Instead, it points to exercise as a credible first-line or add-on option, especially where access to therapy or medication is limited or where people prefer non-drug approaches.
Limits and what comes next
The authors caution that definitions of intensity, frequency and program length differed across studies, making precise prescriptions harder to standardize. Some age groups and exercise formats were also represented by less pooled data than others.
Even with those caveats, the review strengthens the case for tailoring exercise to individual needs, including supervision, setting and duration. Clinicians increasingly emphasize that the most effective program is one a person can start safely and sustain, while tracking symptoms and overall wellbeing.
