How Exercise Could Help Smokers Quit

A large-scale review of research suggests that exercise may be a helpful tool for people trying to quit smoking. Investigators analyzed 59 randomized controlled trials involving more than 9,000 adults to better understand whether physical activity could improve smoking cessation success, reduce cravings, ease withdrawal symptoms and improve mood.

The findings, published in the Journal of Sport and Health Science, showed that exercise provided modest but meaningful benefits for smokers trying to quit. Exercise training increased abstinence, improving continuous abstinence by 15% and increasing seven-day point prevalence abstinence by 21% compared with control groups. In other words, people who participated in exercise programs were more likely to remain smoke-free over time.

Exercise also appeared to reduce smoking intensity. Participants involved in exercise interventions smoked approximately two fewer cigarettes per day than people who did not participate in exercise programs. Researchers say even relatively small reductions in cigarette use may have important health benefits and could help support long-term quit attempts.

One of the most notable findings involved “single-bout” exercise, meaning one short session of physical activity. Investigators found that single exercise sessions produced moderate-to-large reductions in nicotine cravings immediately after exercise and for up to 30 minutes afterward. These short-term effects may be especially helpful for people struggling with intense urges to smoke during quit attempts or stressful situations.

Aerobic exercise, such as walking, jogging, cycling or swimming, appeared to provide the strongest overall benefits for smoking cessation. Higher-intensity workouts also seemed to produce greater reductions in cravings. The team noted that other forms of movement, including resistance training and yoga, may also offer benefits, although there is currently less evidence available for those activities.

Importantly, they emphasized that exercise should not necessarily be viewed as a replacement for traditional smoking cessation methods such as counseling, nicotine replacement therapy or prescription medications. Instead, exercise may work best as part of a broader quit-smoking plan. Because physical activity is low-risk and offers additional physical and mental health benefits, experts believe it may be an accessible strategy for many people trying to quit nicotine.

The review also highlighted a major gap in current research: None of the included studies specifically examined vaping or e-cigarette cessation. As vaping rates continue to rise, investigators say future studies are urgently needed to determine whether exercise could also help people quit e-cigarettes and other nicotine products.

Because it included newer studies and a broader range of participants and exercise approaches, the findings provide a more up-to-date and realistic picture of how physical activity may help people trying to quit smoking.

However, the team also acknowledged several limitations. The studies varied significantly in terms of exercise type, intensity, supervision and how smoking outcomes were measured, which may have affected the consistency of results. Some studies relied on participants self-reporting whether they quit smoking rather than using laboratory confirmation, which could introduce bias. They also noted that many studies did not provide enough information about how consistently participants followed exercise programs, making it difficult to determine the ideal “dose” of exercise needed for smoking cessation benefits. Finally, some of the shorter exercise studies had potential design limitations that may have influenced how cravings were measured after exercise sessions. Despite these limitations, investigators say the overall evidence still supports exercise as a promising, low-risk strategy that could complement traditional smoking cessation treatments.

“These findings support exercise as a safe, accessible and scalable behavioral strategy that may complement established smoking cessation supports,” concluded investigators. “Integrating flexible, aerobic exercise options into cessation programs may enhance quit success, reduce tobacco-related harm and improve population health outcomes.”
