Exercise for Depression and Anxiety: What Works, How Much, and Where to Start

Depression and anxiety are often described in Pakistan as 'tension', 'weakness' or something to pray away, and many people never see a doctor about them. Exercise is not a replacement for proper care, but it is one of the few treatments almost anyone can start today, at home, at no cost — and the research behind it has become impossible to ignore.

Does exercise really help depression?

Yes. A 2024 network meta-analysis in the BMJ pooled 218 randomised trials of 14,170 people who met clinical criteria for depression. Compared with control conditions such as usual care, several kinds of exercise produced moderate reductions in depression. The effects grew with the intensity prescribed, and strength training and yoga were the types people were most likely to stick with. The authors noted that most trials had some risk of bias, so the exact sizes are uncertain — but the direction is consistent across hundreds of studies.

Strength training on its own has a strong record. A 2018 meta-analysis in JAMA Psychiatry of 33 trials and 1,877 people found resistance training significantly reduced depressive symptoms, whether or not people got measurably stronger.

Does exercise help anxiety?

Yes. A 2023 umbrella review in the British Journal of Sports Medicine combined 97 reviews covering 1,039 trials and 128,119 participants. Physical activity produced medium improvements in depression (median effect size -0.43), anxiety (-0.42) and psychological distress (-0.60) compared with usual care, in healthy people, people with mental health conditions and people with chronic illnesses. Higher-intensity activity gave larger benefits, and shorter programmes of 12 weeks or less were more effective than long ones — perhaps because people keep up a short, focused programme more consistently.

How much exercise do you need?

Less than most people assume, especially at first. A 2022 meta-analysis in JAMA Psychiatry followed 191,130 adults in 15 studies. Compared with doing nothing, people who reached the recommended activity level — roughly 2.5 hours of brisk walking a week — had a 25 percent lower risk of developing depression. People doing half that amount still had an 18 percent lower risk. The biggest gains came from moving from nothing to something; extra activity beyond the recommendation added less.

Making it happen when motivation is low

• Lower the bar: on bad days, the rule is 'shoes on and five minutes'. Most days you will keep going; when you don't, five minutes still counts.
• Schedule it like a meeting — the same time each day, ideally in the morning or after work.
• Do it with someone: a friend, sibling, parent or a coach makes skipping harder and adds company.
• Track what you did, not how you felt; mood often lifts after the session, not before.
• Protect sleep: regular bed and wake times, less late-night scrolling — see our sleep guide.
• Go easy on the extremes: exhausting, punishing workouts are not required and can feed anxiety for some people.

When exercise is not enough

Exercise works best as part of care, not as a reason to avoid it. See a doctor or psychologist if low mood or anxiety lasts more than two weeks, stops you working, studying or looking after yourself, or if you are using alcohol, sleeping pills or other substances to cope. Antidepressants and talking therapies are effective, and exercise adds to them. Never stop a prescribed medicine without your doctor's advice.
