A large-scale umbrella review published in the British Journal of Sports Medicine has now provided robust evidence that exercise can significantly reduce symptoms of depression and anxiety, sometimes performing as well as or better than medication or talking therapies. The findings span all ages, with particularly strong benefits observed in young adults and new mothers.
Exercise led to a reduction in depression and anxiety symptoms
The researchers analysed data from hundreds of studies, encompassing tens of thousands of participants. For depression, they reviewed 57 pooled data analyses covering 800 individual studies and 57.930 participants aged 10 to 90. For anxiety, the review included 24 pooled data analyses representing 258 studies and 19.368 participants aged 18 to 67.
The results were clear: exercise led to a medium-sized reduction in depression symptoms and a small to medium-sized reduction in anxiety symptoms. Importantly, these benefits were seen across all types of exercise, from aerobic activities like running and cycling to resistance training and mind-body practices such as yoga and tai chi.
What type of exercise works best?
The study found aerobic exercise such as cycling, running, or swimming had the most substantial impact. But there were differences in how to approach it depending on whether you’re dealing with depression or anxiety.
The researchers noted: “This meta-meta-analysis provides robust evidence that exercise effectively reduced depression and anxiety symptoms across all age groups, comparable with, or exceeding, traditional pharmacological or psychological interventions.”

The depression protocol: intensity and connection
The optimal approach for depression is a “more is more” strategy. It thrives on moderate-to-high intensity and long-term commitment (24+ weeks) to drive neurobiological change. Its defining feature is the social element: exercise is significantly more effective when it is supervised and performed in a group setting, leveraging social support and accountability to boost the antidepressant effect.
The anxiety protocol: low-stress accessibility
The anxiety approach follows a “less is more” rule, prioritizing nervous system regulation. The greatest relief comes from low-intensity activity and short-term programs (up to 8 weeks). It is uniquely defined by its low-frequency requirement. Just 1 or 2 days per week, ensuring that the exercise remains a calming tool rather than a physical stressor that could trigger “fight or flight” sensations.
Why exercise works as treatment
While the exact mechanisms are still being explored, exercise is known to release endorphins, reduce inflammation, and promote neuroplasticity. All of these things can improve mood and reduce anxiety. The social aspect of group exercise may also play a key role, offering a sense of community and support that complements the physical benefits.
If you’re looking to harness the mental health benefits of exercise, consider the following:
For depression: Focus on stimulation and connection through moderate-to-high intensity, long-term commitment, and group settings.
For anxiety: Focuses on calming and accessibility through low-intensity, low-frequency movement and short-term programs to avoid overstressing the nervous system.
As the researchers concluded: “Given the cost-effectiveness, accessibility, and additional physical health benefits of exercise, these results underscore the potential for exercise as a first-line intervention, particularly in settings where traditional mental health treatments may be less accessible or acceptable.”
