Movement and exercise after divorce
You have been told exercise is as good as antidepressants. That headline came from a real study, and a newer review complicates it considerably. Both are on this page, because the honest version is more useful than the motivational one when you are too flattened to get off the sofa.
Movement and Exercise
Exercise has real, moderate antidepressant and anti-anxiety effects backed by large trials, but the newest and most rigorous evidence is more cautious than the headlines suggest. For someone in the middle of a divorce, the honest prescription is small and specific: walking counts, showing up matters more than intensity, and group activity solves a second problem, the friend group that went with the marriage.
A large 2024 analysis in The BMJ found that exercise produces moderate reductions in depression across many different types of activity.
Noetel and colleagues pooled 218 randomized trials with 14,170 participants with depression. Walking or jogging, strength training, and yoga each showed moderate reductions in depressive symptoms compared with active controls; dance showed the largest effect. Effects were similar whether exercise was done individually or in a group, and combining exercise with SSRIs or with psychotherapy produced additional, clinically meaningful benefit. The authors cautioned that the underlying evidence quality is low and few trials followed people for a year or more.
The most rigorous recent Cochrane review is more cautious than the BMJ analysis, and that caution matters more than the headline.
Reported consistently, not settled
A 2026 Cochrane update by Clegg and colleagues pooled 35 trials (1,356 participants) and found a moderate benefit of exercise over no treatment (standardized mean difference -0.62), but when the analysis was limited to only the highest-quality, properly blinded trials, the effect dropped to a small and statistically non-significant -0.18. Exercise showed no significant difference from psychological therapy or from antidepressants in head-to-head trials. A small benefit persisted at follow-up. Unwanted effects from exercise were uncommon.
More vigorous exercise tends to help more, but even light activity shows a real effect, which matters for someone who cannot manage a hard workout.
Reported consistently, not settled
In the BMJ umbrella analysis, the general dose pattern was that greater intensity was associated with greater benefit, but light activity still produced measurable improvement over doing nothing. This is the evidence basis for telling someone in crisis that a walk around the block is not a consolation prize, it is a real intervention with a real if smaller effect.
Group and team exercise show the same average antidepressant benefit as exercising alone, so the choice between them can be made on other grounds, like whether you need people right now.
Reported consistently, not settled
The 2024 BMJ network meta-analysis found effects were similar for individual and group exercise formats. This means the case for joining a class, a run club, or a rec league is not that it works better on mood, it is that it rebuilds a social calendar that divorce often empties out.
The best current evidence puts exercise’s effect somewhere between psychotherapy-comparable and, in the most rigorous trials, modest and uncertain. It is a genuinely useful tool, not a replacement for therapy or medication when those are needed, and a null result on a hard day is not a personal failure.

Walking shows a moderate, real effect in the largest analysis to date. Telling someone in acute crisis to join a gym and hit a program is often the fastest way to get zero exercise at all; telling them to walk for twenty minutes is achievable and evidence-backed.

What to actually do
- Start with a daily walk you can actually keep doing, not a program you will quit in two weeks. Consistency drives the benefit more than intensity.
- If your couple friends went with the marriage, a recurring group activity (a class, a run club, a rec league) solves two problems at once: movement and a reason to see people on a schedule.
- Strength training twice a week is a reasonable, well-supported second step once walking is a habit; it does not need to be complicated to help mood.
- Do not use exercise as your only mental health plan if you are experiencing significant depression, suicidal thoughts, or an inability to function. Pair it with a clinician.
- The most rigorous trials show a smaller, less certain benefit than the popular headlines about the 2024 BMJ study imply. Treat exercise as one real tool among several, not a cure.
- New or intense exercise programs started while sleep and appetite are already disrupted by acute stress can worsen exhaustion; build up gradually.
