What the Cochrane Evidence Says" description: "Short bouts of exercise reduce cigarette cravings and lengthen the time to the next one. That is the best-evidenced lever without medication. How much, how hard, and how to use it in the moment." updated: 2026-09-06 --- # Does exercise reduce nicotine cravings ## TL;DR - Yes. Short bouts of exercise reduce cigarette cravings and lengthen the time until the next one. That is the conclusion of a Cochrane review, and it is the best-evidenced thing you can do for a craving without medication. - The effect is fast and small in size. Under a minute of real effort is enough, which is exactly the shape a craving needs. - What the same review does not find is that exercise programmes, on their own, make people more likely to have quit months later. Exercise is for the moment, not a quit method by itself. - Intensity matters more than duration. Ten hard squats beat a gentle ten-minute walk for this purpose. - If you cannot move, tense: an isometric squeeze held hard for thirty seconds does the same job and nobody sees it. ## What the evidence actually says The Cochrane review on exercise and smoking cessation, updated in 2019, looked at two different questions, and it is worth keeping them apart because they have different answers. The first is whether a short bout of exercise reduces the urge to smoke right now. Across the trials that measured it, it does: cravings drop during and after brief exercise, and the time until the next craving is longer. This is the effect Not One More is built on. The second is whether adding an exercise programme to a quit attempt makes people more likely to be abstinent six or twelve months later. Here the evidence is weaker and the review does not find a clear benefit. Exercise, on its own, is not a way to quit. It is a way to get through a craving, and getting through cravings is how quitting happens. Being clear about that line is what keeps this page honest. The claim is narrow, it is well supported, and it is enough. ## How much, and how hard The trials that found a craving reduction mostly used short bouts of moderate-to-vigorous effort: minutes, not sessions. The consistent pattern is that intensity does the work: effort that makes your legs burn or your breathing pick up, held for long enough to feel, reduces the craving more than a longer, gentler activity does. For a craving that lasts three to five minutes, that translates to something like: - **Ten squats**, done properly, in about thirty seconds. Repeatable anywhere with a metre of floor. - **A flight of stairs**, taken fast. - **Thirty seconds of an isometric squeeze**, every muscle tensed hard, sitting or standing, for when you are somewhere you cannot move. It burns by the end, and it is invisible. Not twenty squats, not a workout. People quitting nicotine are often unfit and mid-craving; an exercise they will not finish delivers nothing. Ten is the number Not One More uses because completion beats intensity. ## Why it works, as far as anyone knows Several mechanisms have been proposed and none is settled: a shift in arousal and mood, a distraction effect, changes in the brain chemistry the craving runs on. What is well established is the effect itself, which is what matters for using it. You do not need to know why the craving falls to notice that it does. One practical point that does seem to hold: the effect is strongest when the exercise happens *during* the craving, not as a background habit. Being generally fit is good for many things. It is the squats at the moment of the urge that act on the urge. ## How to use it in the moment Decide the exercise in advance, so the craving meets an action rather than a choice. Do it as soon as the urge arrives, before the argument starts. Then breathe out slowly a few times, because a long exhale lowers arousal in real time and the two together are stronger than either. Then wait for the craving to pass. It will be falling before you have finished. That sequence is a Hit in Not One More: breathe, burn, ride it out, about two minutes, with the reps counted by your phone's motion sensor so a completed craving is verified rather than self-reported. The verification is not about trust. It is so that the comparison of which action works best for you stays worth reading. ## Questions ### Do I need a gym or a workout? No. The evidence is about brief bouts of effort, not fitness. Ten squats in a kitchen, a flight of stairs, or thirty seconds of tensing everything in a chair is the right scale. A gym session is fine if you enjoy it, but it is not what acts on the craving. ### Does walking count? A brisk walk helps some people, mostly by changing the scene. For the craving itself, intensity matters more than duration, so a short hard effort beats a long gentle one. If walking is what you have, walk fast enough to feel it. ### Can I do this alongside patches or gum? Yes, and you should if you use them. Nicotine replacement handles the chemistry; exercise handles the moment. Combining behavioural support with nicotine replacement is the best-evidenced route to quitting, and the two do not interfere. ### Why does Not One More count the reps? Because a Hit where you actually did the work and a Hit where you tapped through are different data, and the app compares which action works best for you personally. You can skip verification and the Hit still counts as a craving beaten; it is only left out of that comparison, so the comparison stays honest. ## Sources - Ussher MH, Faulkner GEJ, Angus K, Hartmann-Boyce J, Taylor AH, *Exercise interventions for smoking cessation*, Cochrane Database of Systematic Reviews, 2019, CD002295.
