A growing body of research is starting to say something simple and startling:
For many adults with depression, moving your body may help almost as much as talk therapy — and in some cases, may land in the same neighborhood as antidepressant medication.
Not as a cure-all. Not as a replacement for treatment when you need it.
But as a real, evidence-backed tool instead of a throwaway recommendation.
A new Cochrane review — the gold standard for analyzing clinical trials — pulled together 73 randomized studies and nearly 5,000 adults diagnosed with depression to ask a basic question:
When people stick with exercise, how much does their mood change — and how does it compare to therapy or medication?
The answer: more than most people think.
What the New Review Really Found
The updated Cochrane analysis, led by researchers at the University of Lancashire, looked at trials that compared:
Exercise vs. no treatment / control
Exercise vs. psychological therapy
Exercise vs. antidepressant medication
Across the board, exercise clearly beats doing nothing. People who followed a structured exercise program had moderate reductions in depressive symptoms compared with controls.
When researchers compared exercise to psychological therapy, the difference basically disappeared:
Exercise and therapy produced similar improvements in mood.
When they looked at exercise vs. antidepressants, results again suggested comparable benefits, but the evidence was weaker — smaller trials, more variability, and less long-term follow-up. So the message isn’t “exercise replaces meds,” but rather:
Exercise is an evidence-based tool and should not be viewed as an afterthought in treatment discussions.
Next, let's consider which forms of exercise actually made the biggest difference.
The review didn’t crown one magic workout, but some clear patterns emerged:
Intensity:
Light to moderate activity worked better than intense sessions.
Think brisk walking, cycling, gentle jogging, resistance training, classes, or structured home workouts — not “wreck yourself in one day.”
Dose:
The best results tended to occur among people who completed 13 to 36 sessions.
That’s about 2–4 workouts per week for 6–12 weeks — enough time for the brain and body to adapt.
Type of exercise:
Programs that combined resistance work with other forms of movement often did at least as well, and sometimes better, than aerobic exercise alone.
Walking, machines, bands, weights, group classes — the details mattered less than consistency and adherence.
The big takeaway:
You don’t need a perfect plan. You need a repeatable, realistic routine that you can actually stick with.
How Exercise May Ease Depression
Depression isn’t “just in your head.” It affects and is affected by your entire physiology. Exercise appears to matter because it shifts several systems at once:
Brain chemistry: regular movement boosts neuromodulators like dopamine, serotonin, and norepinephrine, which influence mood and motivation.
Neuroplasticity: Exercise boosts BDNF, supporting brain cell resilience and connections.
Stress system: activity helps regulate the HPA axis, reducing chronic overactivation tied to depression.
Inflammation and metabolic health: movement lowers inflammation and improves blood sugar and lipid profiles, all linked to mood.
None of that means exercise “cures” depression for everyone.
It does mean that movement provides the brain and body with better raw materials to work with.
How It Stacks Up Against Therapy and Meds
The Cochrane team came to a careful, nuanced conclusion:
Compared with psychological therapy
Exercise produced similar reductions in depressive symptoms.
For people who dislike or can’t access therapy, this offers another real option.
Compared with antidepressants
Exercise looked broadly comparable in the available trials, but the evidence was of low certainty.
Medication trials tend to be larger and better controlled; exercise studies are often smaller and shorter.
That’s why the right way to frame this is:
Exercise is a powerful treatment component, not a magic replacement.
The best outcomes often come from stacking tools: therapy, meds when needed, plus movement.
Safety: Real Risks vs. Realistic Concerns
In the trials included:
Exercise-related side effects were usually minor:
Muscle soreness
Temporary joint discomfort
Occasional minor injuries
Antidepressant side effects (in comparison groups) included things like:
Fatigue
Nausea and GI upset
Sleep changes, sexual side effects (in some studies)
For most adults cleared for activity, graded exercise is safe. If you have heart disease, joint issues, or significant limitations, first consult a clinician to determine the right activity and intensity.
If You’re Depressed, Where Do You Even Start?
When you’re depressed, “just exercise” can sound dismissive.
Motivation and energy are low, and self-criticism is high.
Set the goal to reduce barriers: Start very small.
- 5–10 minutes of walking.
- One set of body-weight squats and wall push-ups.
- A 10-minute follow-along beginner video.
- Anchor it to something you already do.
After your morning coffee.
Right after lunch.
Before your evening shower.
- Pick something you don’t hate
Walking with a podcast.
Light weights while watching TV.
A simple beginner routine with no equipment.
- Track wins, not perfection.
“I moved 3 days this week” is a win.
“I did 8 minutes instead of 20” is still a win.
The brain responds to patterns, not single intense efforts.
If you’re already in therapy or taking medication, let your clinician know you want to add a structured movement plan. Many providers welcome that and may even help you build it into your overall treatment.
What This Doesn’t Mean
This review does not say:
Everyone with depression should stop their meds.
Exercise alone is enough for everyone, at every level of severity, at every stage.
If movement doesn’t “fix” you, you didn’t try hard enough.
Depression can be severe, life-threatening, and biologically complex. Sometimes the right next steps look more like:
Medication changes
Intensive therapy
Higher levels of care
Safety planning and crisis support
Exercise belongs in the conversation — but never as a weapon to blame yourself.
The Bottom Line
Exercise consistently reduces depressive symptoms compared with no treatment.
It performs about as well as psychological therapy in many trials.
It may offer similar benefits to antidepressants in some contexts, though that evidence is less certain.
Light to moderate activity, repeated over dozens of sessions, matters more than intensity.
Exercise is not a cure, but it is a proven tool that deserves a spot in your treatment plan.
If depression is part of your story, movement isn’t about becoming an athlete.
It’s about one more way to move toward relief.
