For years, researchers have been exploring the effectiveness of exercise for reducing symptoms of depression and anxiety. We know how exercise improves mental health, and that it even rivals the effects of therapy and medication. But much of this research has focused only on specific parts of the population.

Now, for the first time, we have a comprehensive systematic review that highlights how exercise can drive powerful mental health benefits for everyone, at all stages of life. This study also drills down into the best workouts for mental wellbeing, exploring how differences in exercise type, intensity, duration and frequency can impact anxiety and depression.

These 2026 findings published in the British Journal of Sports Medicine are backed up by an overwhelming array of research exploring the mental health benefits sparked by exercise. We’ve summarised the best bits so you can shape a workout routine that winds up the wellness factor and leaves you feeling physically and mentally stronger, healthier and happier.

The quick facts, backed by science

• Exercise can reduce symptoms of depression and anxiety across all age groups.

• Regular exercise can reduce your poor mental health days by almost 50%.
• Group workouts deliver strong mental health benefits, specifically when it comes  to feelings of depression.
• Short, low‑intensity sessions are especially effective for anxiety.
• Team  sports, cycling, and aerobic activities are particularly effective for  improved mental health.
• Optimal benefits come from 45-minute sessions, 3–5 times per week.

How exercise improves mental health

Exercise improves mental health by supporting brain function, emotional regulation, stress management, and overall wellbeing.

Mental and physical health are deeply connected. While exercise is well known for building strength and improving cardiovascular fitness, it also delivers powerful benefits for the brain.

Research links regular physical activity with:

• Reduced symptoms of anxiety and depression
• Improved mood and emotional wellbeing
• Better stress management
• Higher quality sleep
• Enhanced cognitive function
• Greater resilience to everyday challenges

These benefits are driven by several biological changes that occur when we move. Exercise increases the production of neurotransmitters such as serotonin and dopamine, which play a key role in regulating mood. It also helps lower stress hormones like cortisol and boosts levels of Brain-Derived Neurotrophic Factor (BDNF), a protein that supports brain health, learning, and emotional resilience.

In simple terms, movement helps the brain adapt, recover, and function more effectively.

Exercise does more than reduce symptoms

Exercise doesn't just help people feel less anxious or depressed. It also strengthens many of the psychological resources associated with long-term wellbeing. Much of the conversation around mental health focuses on reducing anxiety, stress, or depression. While exercise is highly effective in these areas, emerging research suggests its benefits go much further.

A major 2024 review examining hundreds of studies found strong evidence that physical activity improves resilience, self-esteem, self-efficacy, social support, social connection, body image satisfaction, physical self-worth, positive emotions, wellbeing, and overall mental health.

In other words, exercise doesn't simply reduce symptoms. It helps people develop the psychological foundations that support a happier, healthier life.

Regular movement can help you:

• Build confidence in your abilities
• Feel more emotionally resilient during stressful periods
• Strengthen social connections and support networks
• Develop a greater sense of accomplishment
• Improve self-esteem and body confidence
• Experience more positive emotions and daily wellbeing

These benefits often reinforce one another. As confidence, resilience, and social connection increase, people are more likely to stay active, creating a positive cycle that supports long-term mental wellness.  

What the research about exercise and mental health shows

Research consistently shows that exercise can be one of the most effective lifestyle strategies for supporting mental wellbeing.

One landmark study involving more than 1.2 million people found that those who exercised regularly experienced significantly fewer days of poor mental health than those who didn't.

This research highlighted several key findings:

• Team sports and group activities deliver particular strong mental health benefits
• Cycling and aerobic exercise ranked highly
• Exercise was associated with fewer symptoms of anxiety and depression
• Benefits were greatest for people exercising three to five times per week
• Sessions lasting around 45 minutes appeared most effective

These findings reinforce what many people experience firsthand: exercise can play a meaningful role alongside therapy, medication, and other mental health interventions.

The best types of exercise for mental health

Cardio exercise

Cardio exercise is one of the most consistently effective forms of exercise for improving mood and reducing symptoms of anxiety and depression.

Activities such as running, cycling, brisk walking, dance workouts, and group fitness classes can all provide significant mental wellbeing benefits. Higher-intensity cardio often produces stronger effects than lower-intensity activity, although any movement is better than none.

Strength training

Strength training supports mental wellbeing regardless of how much weight you lift.

Research shows lifting weights can alleviate symptoms of anxiety and scientists believe it can have a similar effect to antidepressant medications or psychotherapy. And you don’t need to lift heavy – there is evidence that the mental health benefits kick in regardless of how much weight you are lifting. This suggests that  the benefits come not only from physical adaptations, but also from increased confidence, accomplishment, and self-efficacy.

If you're not sure where to start, try resistance exercises like squats, lunges, and planks, as these exercises all strengthen the core and promote improved posture, which is linked to a better mood.

Yoga and mindful movement

Yoga combines movement, breathing, and mindfulness, making it particularly effective for supporting mental wellbeing.

Studies suggest yoga-based exercise can ease symptoms of depression while improving relaxation, emotional balance, and recovery from stress. This can be pinned on the fact that practices such as yoga, tai chi, and mindful mobility can help improve heart rate variability which supports nervous system balance and stress regulation.

Why working out with others works better

Group training combines the benefits of movement with the mental health benefits of social connection.

Research suggests the social element of exercise plays a major role in improving wellbeing.

The large-scale study of 1.2 million adults identified team-based activities among the strongest performers for mental health benefits. A separate 12-week study found participants in group workouts (in this case LES MILLS CORE™) reported greater improvements in:

• Stress reduction
• Emotional wellbeing
• Mental quality of life
• Physical quality of life

Researchers have also found that group training can increase enjoyment, exertion, and satisfaction.

Beyond motivation and accountability, social support and social connection are now recognized as two of the strongest pathways through which physical activity improves mental health. Fitness classes, sports teams, and exercise communities can help people feel a greater sense of belonging, an important contributor to resilience and long-term wellbeing.

How much exercise is enough?

For most people, 30–45 minutes of exercise three to five times per week appears to provide the greatest mental health benefits.

The sweet spot: Research suggests the strongest mental health outcomes come from:
- 30–45 minutes per session
- Three to five workouts per week

This level of activity appears to deliver meaningful benefits while remaining sustainable.

Why more exercise isn't always better

Researchers have identified a U-shaped relationship between exercise and mental health.

Those exercising less than three times per week tend to report poorer wellbeing. Interestingly, excessively high exercise volumes may also be associated with diminishing returns.

The goal is consistency, not excess.

Small amounts of exercise still matter

You don't need long workouts to support mental wellbeing. Small amounts of movement can make a measurable difference.

Research shows:

• As little as 10 minutes of physical exercise per week can result in increased levels of happiness.
• Twenty minutes of moderate-intensity aerobic exercise to your morning routine it can provide an immediate mood boost – and the positive effects can last up to 12 hours.
• Those who clock up at least 30 minutes of physical activity on most days are 30 percent more likely to report being ‘happy’ than those who don’t.
• The mood-enhancing benefits of exercise are long-lasting – they can still be in your system for weeks following your exercise!

Combining exercise and mindfulness

Combining movement with mindfulness may amplify mental health benefits.

Research indicates mindfulness practices can:

• Improve emotional regulation
• Strengthen self-awareness
• Reduce reactivity to stress
• Increase self-compassion
• Support long-term wellbeing

Simple practices such as breathing exercises, meditation, mindful walking, or gentle mobility sessions can complement a regular exercise routine and help support
emotional balance.
