Exercise for Depression: How It Helps and How to Start When You Have No Energy

What depression does to your energy

Clinical depression, or major depressive disorder, is more than feeling a bit down. It usually means a low mood or a loss of interest that lasts for weeks, along with changes in sleep, appetite, focus, and energy. Many people describe it as moving through wet cement.

When everything feels heavy, pulling back makes sense. Staying in, skipping plans, and resting are ways of protecting yourself when the world feels like too much. That protection has a price, though. The less you move and the less you do, the fewer moments you have that might lift your mood, and the heavier the next day can feel.

Exercise is one of the few ways to push gently against that loop without needing to feel better first. The version you start with can be so small it feels almost silly.

Does exercise help depression? What the research shows

Yes, for many people, whether you call it exercise or working out. A 2024 review in the BMJ pooled 218 clinical studies of people with major depression, more than 14,000 people in all. It found that walking or jogging, yoga, and strength training each brought moderate drops in depression compared with usual care.

Harder workouts went with bigger improvements. Exercise seemed to help about as well whether people started out mildly or severely depressed. The authors noted that most of the studies had design weaknesses, so the confidence in each result is lower than the size of the review suggests. Even so, they concluded that exercise could be considered alongside therapy and antidepressants as a core treatment.

The benefit is not limited to depression. An overview of 97 reviews, covering more than 128,000 adults, found that physical activity brought medium-sized improvements in both depression and anxiety compared with usual care. Many people with depression also live with anxiety, and the same habits tend to help with both.

Why exercise helps with depression

You have probably read that exercise works because of endorphins, the “feel-good” chemicals the body releases when you move. That idea is popular, but it has not been proven. A 2022 review in Molecular Psychiatry found that the ways exercise eases depression are not fully understood. Single workouts shift several brain chemicals for a short time, but no one has shown which of those changes, if any, explains the lift in mood.

What people notice is often simpler. Moving your body can take the edge off tension and lower stress levels for a while. Finishing something, even a short walk, gives you a small sense of accomplishment on a day that may not have many. Getting stronger can change how you feel in your own body. And a walk outside, or a class with other people in it, puts you back in contact with the world you may have been pulling away from.

The best exercise for depression

There is no single great exercise that keeps depression at bay. The best exercise for depression is the one you will do again next week. Several kinds have research behind them, so you get to choose based on what feels possible.

• Walking or jogging. Walking had some of the strongest results in the BMJ review, and it needs no equipment, no gym, and no skill. The steady rhythm can be calming.
• Strength training. Lifting weights, using resistance bands, or doing bodyweight moves like squats against a chair. In the same review, people tended to stick with strength training and yoga more than other options.
• Yoga. Yoga combines movement, breathing, and focused attention. A review of 12 clinical studies found that yoga reduced depression in the short term, both in people diagnosed with depression and in people with elevated symptoms.
• Tai chi or qigong. Slow, gentle movement that also showed benefits, and a good fit if your body feels stiff or tired.

Group exercise has its own advantages. A walking group, a class, or a friend who expects you can provide the social contact depression tends to strip away. If you would rather be alone, that works too. Getting outside, even briefly, adds daylight and a change of scene.

How much exercise for depression?

Less than you might fear. A review of five clinical studies of exercise for depression found that the programs that worked were mostly moderate aerobic exercise three times a week, such as walking or cycling. The reviewers recommended keeping it up for at least nine weeks. Both group and solo programs helped, and the reviewers suggested some supervision.

You also don’t need to push hard to get something out of it. The BMJ review found bigger effects with harder exercise, but an earlier review of exercise for clinical depression concluded that exercise need not be lengthy or intense to help, and that you don’t have to get fitter to feel the benefit. Moderate effort, where you can still talk but feel your breathing pick up, tends to feel better and is easier to keep doing.

A reasonable goal is to work up to moving most days. A reasonable starting point is much smaller than that.

Before starting a new exercise routine, check with your doctor if you have a heart condition, an injury, or another health issue, or if you haven’t been active in a long time. They can help you pick a safe starting point.

Exercise is part of treatment, not a replacement for it

Exercise is a real part of treating depression. It is not a substitute for therapy or medication, especially when depression is moderate or severe. If you take an antidepressant, keep taking it as prescribed. Any change to medication should go through your prescriber, even if exercise is making you feel better.

Therapy works on things exercise can’t reach: why the low periods come, what they are protecting you from, and how your relationships and history shape them. Psychodynamic therapy, emotion-focused therapy, cognitive behavioral therapy, and interpersonal therapy are all well-studied approaches, and the fit between you and your therapist matters too. Psychodynamic therapy looks at the patterns underneath the depression, not only the symptoms on top.

It may be time to reach out if you have been trying to move more for a few weeks and nothing has shifted, if you can’t get started at all, or if depression is getting in the way of work, sleep, or the people you care about. Our depression therapy in DC can sit alongside whatever movement you are able to do, and help with the parts exercise can’t.
