A sweeping new systematic review finds that exercise — even a single session — can meaningfully reduce nicotine cravings and improve the odds of quitting smoking. Researchers say it works best as a complement to existing cessation tools like counseling and medication.
If you’ve ever tried to quit smoking, you know how brutal the cravings can be. A major new review suggests that lacing up your sneakers might help — and fast.
Researchers from the Alliance for Research in Exercise, Nutrition and Activity (ARENA) at Adelaide University in Australia analyzed data from 59 randomized controlled trials involving more than 9,000 participants and found that structured exercise programs can modestly improve long-term quit rates, while a single workout can produce significant reductions in nicotine cravings almost immediately.
The review, published April 7 in the Journal of Sport and Health Science, was led by Ben Singh and Carol Maher at the University of South Australia’s ARENA research group.
What the Numbers Say
The scope of the review is notable. Researchers combed through 11 databases covering studies published up to March 2025, making it one of the most comprehensive analyses of exercise and smoking cessation to date. The included trials covered a wide range of physical activity types — aerobic exercise, resistance training, yoga, high-intensity interval training (HIIT), and lifestyle-based programs — giving the findings broader applicability than earlier, narrower reviews.
When it came to long-term outcomes, participants in exercise programs were 15% more likely to achieve continuous abstinence compared to control groups, based on data from 23 trials. A separate analysis of 18 trials found exercise increased seven-day point prevalence abstinence — a standard quit-smoking benchmark — by 21%. People who exercised also smoked roughly two fewer cigarettes per day than those who didn’t.
The most striking findings, however, involved short-term cravings. In studies that examined the immediate effects of a single workout, exercise produced moderate-to-large reductions in nicotine urges right after the session, with benefits still measurable 10, 20, and even 30 minutes later. Higher-intensity exercise generated the largest craving reductions, suggesting that how hard you work out may matter, not just whether you move at all.
Why It Matters for Young Adults
Tobacco use remains one of the leading preventable causes of death globally, and young adults represent a critical demographic in smoking cessation efforts. College campuses and early professional environments are often high-stress settings where smoking — or vaping — can become habitual. Quit rates using traditional methods like nicotine replacement therapy and prescription medications remain disappointingly low, and relapse is common.
Exercise offers something different: it’s largely free, doesn’t require a prescription, and carries its own set of physical and mental health benefits that align with goals many students already have. The research suggests exercise could be particularly useful during high-craving moments — right after class, before an exam, or during a stressful shift — when the urge to light up is strongest and the risk of relapse is highest.
Important Caveats
The researchers are careful to note that exercise is not a cure-all. While the effects on continuous abstinence were statistically meaningful, the overall certainty of evidence for long-term quit outcomes was rated as low, due to variability across studies, potential bias, and limited precision. Exercise did not significantly reduce cravings over long-term training programs — only in the immediate aftermath of individual sessions. The researchers stress that exercise should be viewed as a promising add-on strategy, not a replacement for proven cessation treatments.
There’s also a glaring gap in the research: not a single included trial looked at vaping cessation. As e-cigarettes and dual use of cigarettes and vapes become increasingly common — especially among younger adults — the absence of vaping-specific data is a significant limitation the authors say must be addressed in future research.
What’s Next
The researchers call for more studies examining which types of exercise work best, at what intensity, and how those programs can be delivered most effectively — whether through community programs, digital platforms, or integration into existing health services. For now, the evidence is strong enough to suggest that adding physical activity to a quit plan is a smart move, even if the science on the best approach is still developing.
For students and young professionals trying to kick the habit, the takeaway is practical: if a craving hits, a brisk walk, a quick run, or even a high-intensity workout might take the edge off — and might just help make the quit stick.
