Exercise is a powerful depression treatment — but the dose matters. Research now allows us to be specific about what type, duration, and frequency most effectively addresses depression.
The Research on Exercise Dose for Depression
Meta-analyses consistently find that for depression:
- Frequency: 3-5 sessions per week is optimal
- Duration: 30-45 minutes per session produces maximum benefit
- Intensity: Moderate (able to talk, but not sing) is sufficient — higher isn't necessarily better for depression
- Type: Aerobic exercise has most evidence; strength training shows growing evidence
Getting Started with Exercise for Depression
When depression makes motivation low, start with 5 minutes. The hardest part is starting — not continuing.
Exercise works for depression through immediate neurochemical effects (mood boost) and long-term neurological changes (increased resilience).
Exercise as Sustainable Depression Treatment
Unlike some depression medications, exercise has positive side effects and the benefits increase over time rather than requiring dose escalation.
