Exercise for depression: what we tell patients.

Patients ask whether exercise is a real part of depression treatment or a polite suggestion. Three large reviews published between 2023 and 2026 let us answer with numbers instead of encouragement. This is the summary we give, including the parts where the evidence is thin.

This post is education from the practice, not medical advice. It summarizes published research on exercise and depression. It is not a recommendation about any individual's treatment or activity level.

The short answer

Exercise reduces depression symptoms by a moderate amount on average. That sentence is now supported by an updated Cochrane review from January 2026 covering 73 randomized trials and 4,985 adults, by a 2024 BMJ analysis of 218 studies and 14,170 people with major depression, and by a British Journal of Sports Medicine umbrella review combining 97 reviews, 1,039 trials, and 128,119 participants. In the few trials that compared exercise directly with psychological therapy, the two reduced symptoms by about the same amount. The same was true in the even fewer trials comparing exercise with antidepressant medication. Those head to head comparisons are small, and this practice does not present exercise as a replacement for either treatment. We present it as a supported part of a plan.

What we are careful about

The reviewers are careful, so we are. Cochrane rated most of its comparisons low certainty, the BMJ authors rated their confidence low to very low after finding only one study at low risk of bias, and the umbrella review found most of its source reviews critically low in quality. The reviews disagree about intensity: two link harder exercise to larger gains, while Cochrane found light to moderate intensity looking better. Almost no trials tracked people after the programs ended, so nobody knows how long the benefit lasts. Patients deserve that whole picture, because advice given with false confidence stops being trusted when it meets a hard week.

How it fits care here

At this practice, activity comes up the way sleep does: at intake, and again when it changes. A patient whose movement has stopped has often worsened before the questionnaires show it, and a structured, repeatable activity is one of the few additions to a treatment plan with randomized trial evidence behind it. The trial programs that worked were scheduled programs, commonly totaling somewhere between 13 and 36 sessions in the Cochrane review, in forms ranging from walking and mixed programs to resistance training and yoga. What fits a particular patient depends on their health, their history, and their life, and it is decided in the visit, not in a blog post. Anyone with a medical condition that limits activity should clear changes with their clinician first.

Read more, by door

This practice has two clinical doors, and each keeps its own blog. For the combined therapy and medication perspective, psych.us has published does exercise help depression, answered with the evidence and its limits. For the medication-focused read, PsychMed Care has published exercise and depression, checked against the reviews, including what the findings mean next to a medication plan. When reading has done all it can, the booking page is the next step.

This post is educational and does not create a treatment relationship. Research findings describe large groups and cannot predict an individual's response to exercise, therapy, or medication. Patients of this practice who are considering a change in activity, or who notice their activity collapsing, should raise it at a visit. Nothing here is a reason to change a working treatment on your own.
