The best exercise for depression, according to 218 studies

Walking, yoga or lifting weights? Large reviews of hundreds of trials now show which workouts ease depression most, and why intensity matters more than you think.

November in north India has a way of shrinking life. The evenings close in by half past five, the smog keeps people off the roads and terraces, and plenty of us notice our mood sliding along with our step count.

That link between moving and feeling better is not just folk wisdom. Depression affects an estimated 5.2% of adults worldwide, around 322 million people, and it is about 1.5 times more common among women than men ¹. Over the last few years, some very large reviews have asked a sharper question than "does exercise help?" They have asked which kind helps, how hard you need to work, and how much is enough.

What the biggest study on exercise and depression found

In 2024, a team led by Michael Noetel at the University of Queensland published a network meta-analysis in the BMJ that pooled 218 studies with 14,170 participants, all randomised trials of people with depression ². A network meta-analysis lets researchers compare many treatments against each other at once, even ones that were never tested head to head.

Compared with active control groups, the clearest results looked like this, shown as effect sizes where a bigger number means a bigger drop in symptoms ²:

• Walking or jogging: 0.62, a moderate reduction
• Yoga: 0.55
• Strength training: 0.49
• Mixed aerobic exercise: 0.43
• Tai chi or qigong: 0.42

For context, the same analysis put SSRIs, a common class of antidepressant, at an effect size of 0.26 against active controls ². The authors concluded that exercise is an effective treatment for depression, with walking or jogging, yoga and strength training standing out, "particularly when intense" ².

That last phrase matters, so hold on to it.

Does it matter how hard you exercise?

It seems to. Noetel's team found that the effects of exercise were proportional to the intensity prescribed, with stronger expected effects for vigorous exercise than for light activity ².

A separate umbrella review from the University of South Australia, published in the British Journal of Sports Medicine in 2023, reached a similar view from a different angle ³. Ben Singh and colleagues gathered 97 systematic reviews covering 1,039 trials and more than 128,000 participants. Physical activity had medium effects on depression (median effect size 0.43) and anxiety (0.42) compared with usual care, and higher intensity activity was linked with bigger improvements ³. For depression, the median effect was 0.22 for low intensity, 0.56 for moderate and 0.70 for high ³.

You do not need to love the gym. You need to get a little out of breath, a few times a week, for long enough to notice.

One more finding from Singh's review is worth knowing: programmes of 12 weeks or less showed larger effects than longer ones ³. That does not mean you should stop after three months. It suggests the early weeks are where many people feel the clearest lift, which is useful to know when motivation is low.

Is exercise as good as therapy or medicine?

You may have seen headlines saying exercise beats medication. The careful answer is more modest. Singh's team wrote that the effects they found were "comparable to or slightly greater than" those seen for psychotherapy and medication in other studies ³. That is an indirect comparison across different research, not a direct trial, and the authors said more work is needed to confirm it.

There are other honest caveats. Most of the reviews in Singh's analysis were rated "critically low" for quality, and most of the evidence concerned mild to moderate depression ³. In the BMJ analysis, confidence in the results was rated low for walking or jogging and very low for the other treatments, and only one study met the Cochrane criteria for low risk of bias ². Trials of exercise are hard to blind; you always know whether you are jogging.

So the fair reading is this. Exercise is a well supported option that works alongside, not instead of, professional care. If you are on medication or seeing a therapist, exercise is something to add, and changes to treatment should only ever happen with your doctor.

Which workout suits whom?

The BMJ data hinted at some patterns, though the authors treated them as tentative ²:

• Strength training appeared more effective in younger participants
• Yoga appeared somewhat more effective in older adults
• Strength training and cycling showed larger effects for women, while yoga and tai chi showed larger effects for men

These are averages across trials, not rules for you. The best programme is still the one you will actually turn up for on a cold, grey Tuesday.

How much exercise helps prevent depression?

Treatment is one question. Prevention is another. A 2022 meta-analysis in JAMA Psychiatry led by Matthew Pearce at the University of Cambridge combined 15 prospective studies with more than 2 million person-years of follow-up ⁴. These were observational studies, so they show an association rather than proof that activity prevents depression.

Even so, the pattern was striking. People doing half the recommended weekly volume of activity (4.4 marginal MET-hours a week) had a relative risk of 0.82 for depression, roughly 18% lower than inactive people ⁴. At the full recommended volume of 8.8 MET-hours, about two and a half hours of brisk walking a week, the relative risk was 0.75 ⁴. Going well beyond that added only a little more, with a relative risk of 0.72 at 17.5 MET-hours ⁴. The researchers estimated that around 11.5% of depression cases might have been prevented if all adults had reached that 8.8 mark ⁴.

The biggest gain, in other words, comes from moving from nothing to something.

What to do this week

None of this needs a fancy plan. A sensible start for a healthy adult:

1. Pick one of the top three from the trials: brisk walking or jogging, yoga, or strength training. Choose the one you dislike least.
2. Aim for three sessions this week of 20 to 40 minutes each. If that feels like too much, start with 10 minutes and build up.
3. Let at least part of each session feel hard enough that talking in full sentences gets difficult. That is moderate to vigorous intensity, the range where the trials saw the larger effects.
4. On bad air days, take it indoors. A home strength circuit, stair climbs or a yoga session count fully, and we have covered how to judge the AQI in our guide to exercising in smog.
5. Book a buddy. Group walks, a class or a friend on a video call make it far harder to skip.
6. Give it a fair trial of six to eight weeks before judging whether it helps you.

Exercise is not a cure-all, and low mood that lasts most days for two weeks or more, or that stops you working, sleeping or eating normally, deserves a proper conversation with a doctor or mental health professional. If you have a health condition, are pregnant or take regular medication, speak to your doctor before starting vigorous exercise.

What the research does show is generous. A brisk walk, a yoga mat or a pair of dumbbells, used a few times a week, is one of the most reliable mood tools most of us already own.
