- Exercisers reported 43.2% fewer poor-mental-health days than matched non-exercisers (association). (Chekroud SR et al. 2018)
- Walking or jogging, yoga and strength training gave moderate reductions in depression vs active controls. (Noetel M et al. 2024)
- Physical activity had medium effects on depression, anxiety and distress across 97 reviews. (Singh B et al. 2023)
Jumpstart: 10 push-ups. Right now.
💪 Jumpstart: if you have time to read this, you have time for 10 push-ups (knees count). Seriously, actually do it. Now. Then come back three times a week and do it again.

The results
What this means: People who exercised reported about 43% fewer bad mental-health days than similar people who didn't. This study shows a link, not proof that exercise caused it.
Source: Chekroud et al. 2018, Lancet Psychiatry, 1,237,194 US adults. The abstract reports 1.49 fewer days (43.2% fewer); the bar values are calculated from those two numbers. doi:10.1016/S2215-0366(18)30227-X
What this means: Every type helped, with moderate effects. Walking or jogging, yoga and strength training did best, and harder sessions helped more. The authors rate confidence in this evidence as low, so treat it as promising rather than proven. By convention an effect size of about 0.2 is small, 0.5 medium and 0.8 large.

What this means: Moving had medium-sized benefits for stress, anxiety and mood across many kinds of adults, and higher intensity helped more. Many of the included reviews were low quality, so the size is approximate. By convention an effect size of about 0.2 is small, 0.5 medium and 0.8 large.

In 1.2 million US adults, people who exercised reported 43% fewer days of poor mental health than matched non-exercisers (Chekroud 2018, an association study). Across 218 trials, exercise reduced depression symptoms, with walking, jogging, yoga and strength training among the most effective (Noetel 2024).
The research (verified against the published abstracts)
- Chekroud SR et al. (2018). Association between physical exercise and mental health in 1.2 million individuals in the USA between 2011 and 2015: a cross-sectional study. Lancet Psychiatry 5(9):739–746. doi:10.1016/S2215-0366(18)30227-X
1,237,194 US adults. People who exercised reported 1.49 fewer days of poor mental health per month (43.2% fewer) than matched non-exercisers. This is cross-sectional, so it shows association, not cause. The largest associations were for team sports, cycling and aerobic/gym activities, at about 45 minutes and 3–5 times a week. - Noetel M et al. (2024).

218 studies, 14,170 participants with major depression. Compared with active controls, walking or jogging (g −0.62), yoga (g −0.55), strength training (g −0.49), mixed aerobic exercise (g −0.43) and tai chi/qigong (g −0.42) gave moderate reductions in depression. Effects were proportional to the intensity prescribed. Evidence confidence was rated low for walking/jogging and very low for the others, because only one study met Cochrane criteria for low risk of bias. - Singh B et al. (2023). Effectiveness of physical activity interventions for improving depression, anxiety and distress: an overview of systematic reviews. British Journal of Sports Medicine 57(18):1203–1209. doi:10.1136/bjsports-2022-106195
Umbrella review: 97 reviews, 1,039 trials, 128,119 adults. Physical activity had medium effects on depression (median ES −0.43), anxiety (−0.42) and psychological distress (−0.60) versus usual care. Higher intensity was linked to greater improvement; effectiveness diminished with longer interventions. Note: 77 of the 97 reviews were rated critically low quality (AMSTAR).
