Depression affects nearly one in five adults in the United States at some point in their lives, making it a significant public health concern1 . While psychotherapy and antidepressants remain first-line treatments, many individuals seek alternative or complementary options due to stigma, side effects, or incomplete response2 . Exercise, including activities like yoga, walking, and jogging, has emerged as an effective treatment that can be tailored to individual preferences and integrated with other therapies3 . Evidence shows that supervised, group-based, moderate-intensity aerobic exercise is particularly beneficial for reducing depressive symptoms across diverse populations3 .
Best Exercises for Depression
A comprehensive 2023 systematic review and network meta-analysis of randomized controlled trials identified several exercise modalities that significantly reduce depression symptoms4 . Walking or jogging demonstrated the largest effect size, followed closely by yoga and strength training4 . These exercises showed moderate reductions in depression compared to control conditions, making them viable treatment options alongside psychotherapy and antidepressants4 .
Key findings include:
- Walking or jogging had the greatest impact on depression with a moderate effect size (Hedges’ g −0.62) based on data from 51 studies involving 1,210 participants4 .
- Yoga also showed a moderate effect (g −0.55) from 33 studies with 1,047 participants4 .
- Strength training had a slightly smaller but still significant effect (g −0.49) from 22 studies including 643 participants4 .
- Other exercise types such as mixed aerobic exercises and tai chi or qigong also reduced depressive symptoms but with smaller effect sizes4 .
- Exercise effects were proportional to the intensity prescribed, with vigorous exercise generally yielding greater symptom reductions5 .
- Strength training and yoga were better tolerated, with lower dropout rates compared to controls, indicating higher acceptability4 .
- These benefits were consistent regardless of participants’ baseline depression severity or presence of comorbidities4 .
While the evidence is promising, most trials had small sample sizes and a high risk of bias, which limits confidence in the findings4 . Long-term outcomes and sex-specific effects remain unclear, as subgroup analyses by sex were not reported in the largest meta-analysis4 . Nevertheless, walking, jogging, yoga, and strength training stand out as effective and accessible exercise options for managing depression4 6.
How Exercise Helps Depression
The biological and psychological mechanisms underlying exercise’s antidepressant effects are complex and multifaceted. Current research highlights several key pathways through which physical activity alleviates depressive symptoms6 7:
“For some people it works as well as antidepressants, although exercise alone isn't enough for someone with severe depression.”
— Dr. Michael Craig Miller, assistant professor of psychiatry at Harvard Medical School11
- Neurotransmitter modulation: Exercise influences brain chemicals such as serotonin and dopamine, which regulate mood and emotional well-being6 7.
- Neuroplasticity enhancement: Physical activity promotes growth and connectivity of nerve cells, particularly in the hippocampus, a brain region involved in mood regulation7 .
- Hormonal regulation: Exercise helps balance the hypothalamic-pituitary-adrenal (HPA) axis, reducing stress hormone levels that are often elevated in depression6 .
- Immune system modulation: Regular exercise reduces systemic inflammation, which has been linked to depressive symptoms6 .
- Psychological benefits: Yoga, in particular, improves mindfulness, self-efficacy, and social connectedness—factors known to protect against depression8 9.
Yoga combines physical postures, breathing exercises, and meditation, which complement cognitive behavioral therapy (CBT) by enhancing behavioral activation and thought disputation9 . Group yoga sessions have been shown to increase engagement and positive feelings, supporting longer-term access to CBT concepts8 . These psychological and behavioral mechanisms work alongside physiological changes to produce antidepressant effects.
Exercise also provides acute mood enhancement, often within minutes of moderate activity, which can motivate continued participation10 . The combination of social interaction, mindfulness, immersion in natural environments (e.g., walking outdoors), and positive affect contributes to the overall therapeutic effect4 . Despite these insights, further research is needed to fully elucidate the mediators of exercise’s benefits in depression4 .
“The link between exercise and mood is pretty strong. Usually within five minutes after moderate exercise you get a mood-enhancement effect.”
— Michael Otto, PhD, professor of psychology at Boston University10
Choosing the Right Workout
Selecting an appropriate exercise regimen for depression should consider individual preferences, tolerability, and medical advice to optimize adherence and outcomes6 3. Evidence supports supervised, group-based, moderate-intensity aerobic exercise such as walking and jogging as particularly effective3 . Yoga and strength training also offer significant benefits and may be preferred by some patients due to their acceptability and lower dropout rates4 3.
💡 Did You Know?
Several studies have demonstrated that habitual exercise can positively affect depressive symptoms, resulting in enhanced mental health and quality of life12 .
| Exercise Type | Effect Size (Hedges’ g) | Acceptability (Dropout Rate) | Intensity Level | Notes |
|---|---|---|---|---|
| Walking/Jogging | −0.62 | Moderate | Moderate to vigorous | Most effective overall4 |
| Yoga | −0.55 | High (lower dropout) | Low to moderate | Enhances mindfulness8 9 |
| Strength Training | −0.49 | High (lower dropout) | Moderate to vigorous | Well tolerated4 |
| Mixed Aerobic | −0.43 | Moderate | Moderate to vigorous | Includes various aerobic forms4 |
| Tai Chi/Qigong | −0.42 | Moderate | Low to moderate | Mind-body benefits4 |
Important considerations for choosing the right workout include:
- Intensity: While vigorous exercise tends to produce stronger reductions in depressive symptoms, even low- to moderate-intensity activities like walking and yoga provide meaningful benefits4 65.
- Modality: Walking or jogging, yoga, and strength training are the most supported exercise types for depression treatment4 .
- Setting: Group exercise can enhance social support and motivation, improving engagement, especially for yoga4 .
- Personalization: Tailoring exercise to individual needs, preferences, and physical capabilities promotes adherence and effectiveness6 .
- Integration: Combining exercise with psychotherapy or antidepressants may enhance treatment outcomes4 .
A practical approach is to start with manageable activities, such as five minutes of walking daily, gradually increasing duration and intensity over time11 . Patients should choose exercises they enjoy to sustain long-term participation, as consistent activity is key to maintaining mental health benefits11 .
