Exercise is famous for protecting the heart, lifting mood, and extending life. Its effects on sexual desire and performance get far less attention, yet scientists have been studying this link for decades. The short version of the evidence is encouraging, with one important twist. Moderate, regular exercise appears genuinely helpful. Extreme training may backfire.
This article walks through what controlled trials and large reviews actually found, for men and women, and separates documented facts from common gym myths.
The short answer
Yes, exercise can improve sexual performance, and the evidence is strongest for aerobic exercise and erectile function in men. A 2017 meta-analysis of seven randomized controlled trials found that exercise interventions significantly improved erectile function scores, with moderate to vigorous aerobic activity showing the clearest benefit [1]. A stricter 2024 meta-analysis that excluded men taking erection medication reached the same conclusion, finding a significant overall benefit driven by aerobic training alone [2].
For women, the evidence is thinner but points the same direction. Laboratory studies show a single bout of exercise can increase genital arousal for the following 15 to 30 minutes [5, 6]. And a 2025 randomized trial found that pelvic floor muscle training improved overall sexual function in women of reproductive age within two to three months [7].
What researchers mean by sexual performance
Sexual performance is not one thing. Researchers typically measure several separate domains: desire, meaning motivation to have sex; arousal, meaning the body’s physical response; erectile function in men; orgasm; and satisfaction [5]. This matters because exercise affects these domains differently, and studies measure them differently.
Erectile function: the best-documented benefit
The landmark analysis came from the British Journal of Sports Medicine in 2017. It pooled seven randomized controlled trials with 478 participants. Men in exercise programs improved their scores on the International Index of Erectile Function, the standard clinical questionnaire, by an average of about 3.85 points compared with controls. Benefits appeared in both short and long programs, and whether exercise was used alone or alongside usual care [1].
A 2024 meta-analysis in the journal Andrology sharpened the picture. It included only men who were not taking erection drugs and had not had prostate surgery, removing two factors that could distort earlier results. Across seven trials with 470 men, exercise produced a significant improvement overall. But the subgroup results were striking: aerobic training alone clearly worked, while pelvic floor training alone and combined aerobic-plus-resistance programs did not show a significant benefit in this particular analysis [2].
The effective programs in these trials typically involved three to five sessions per week, 120 to 180 minutes per week, at 40 to 79 percent of maximum heart rate. One study cited in the analysis found that higher volumes, 200 to 300 minutes per week of moderate exercise, produced stronger improvements than low volumes under 150 minutes [2].
Importantly, these were not all young, healthy men. The trials included participants with obesity, high blood pressure, heart disease, stroke, and hormone deficiency, and the benefits held across these groups [2]. The authors do urge caution, since the trials were small and blinding participants is impossible in exercise studies [1, 2].
Desire and libido: more is not always better
Here the research delivers a surprising twist. Two large surveys by exercise physiologist Anthony Hackney and colleagues found that very high training loads were linked to lower sexual desire, not higher.
In a 2017 study of more than 1,000 healthy men, those training at the lowest or moderate intensities had roughly seven times and three times the odds of reporting high or normal libido compared with men training at the highest intensity. Men with shorter or moderate training histories also had higher libido than those with the longest training exposure [3].
A 2022 follow-up focused on endurance runners found similar results. Among more than 1,000 regular runners, men doing marathon-specific training reported libido scores about 20 percent lower than other runners. The biggest factors were total years of training and the proportion of training done at high intensity, both showing an inverse relationship with desire [4]. The researchers note that chronic fatigue, low energy availability, and reduced testosterone are possible explanations, though their survey design could not prove cause [4].
The pattern suggests a curve, not a straight line. Moderate activity is associated with healthy desire, while chronic, very high-volume endurance training may suppress it [3, 4].
Women: arousal, timing, and pelvic floor strength
Some of the most creative research on this topic comes from laboratory studies of women’s sexual arousal. In a 2012 study, 47 women experiencing arousal problems from antidepressant medication exercised for 20 minutes on a treadmill and then viewed erotic films. Their genital arousal was significantly higher than on no-exercise days, both 5 and 15 minutes after the workout. Women with the most severe arousal difficulties showed the largest improvements [6].
Timing matters. Earlier studies in healthy women found that genital arousal was significantly increased 15 and 30 minutes after exercise, but not immediately after, when blood is still being routed to working muscles [5]. A scientific review concludes that moderate activation of the sympathetic nervous system, the body’s alertness system, is the likely mechanism, and that both very low and very high activation are less helpful [5].
The same review notes that regular, long-term exercise likely benefits women’s sexual well-being indirectly, through better cardiovascular health, improved mood, and more positive body image [5]. Separately, a 2025 randomized controlled trial of 77 women of reproductive age found that structured pelvic floor muscle exercises produced significantly better sexual function scores than no training, with improvements across desire, arousal, lubrication, orgasm, satisfaction, and pain by the second and third months [7].
Why exercise may help
Researchers point to several overlapping pathways:
- Blood flow. Arousal and erections depend on healthy blood vessels. Exercise improves vascular function throughout the body, including the genitals [2, 5].
- The nervous system. Moderate exercise primes the sympathetic nervous system in a way that facilitates arousal [5, 6].
- Mood and body image. Regular exercise reduces stress and depression and improves body confidence, all of which feed into desire and satisfaction [5].
- Pelvic floor muscles. These muscles support arousal, orgasm, and erection, and targeted training has documented benefits, especially in women [7].
- Energy and fitness. Better cardiovascular fitness reduces fatigue during sexual activity [5].
Myths and facts, clearly separated
The following claims are common beliefs. Each is a myth. After each is what the documented evidence actually shows.
Myth: “Any exercise fixes erection problems.” Documented fact: moderate to vigorous aerobic exercise is the type with the clearest support. In the 2024 meta-analysis, pelvic floor training alone and combined aerobic-plus-resistance programs did not significantly improve erectile function, though the authors note the evidence for these modes is limited and other reviews have found pelvic floor benefits in specific groups of men [2].
Myth: “The more you train, the better your sex life.” Documented fact: the relationship appears curved. Men at the highest training intensities and longest training histories reported the lowest libido, and marathon-specific training was associated with about 20 percent lower desire in one large survey [3, 4].
Myth: “A hard workout right before sex boosts performance.” Documented fact: immediately after exercise, genital arousal was not increased in laboratory studies. The facilitatory effect appeared 15 to 30 minutes later [5, 6].
Myth: “This only works for young, healthy people.” Documented fact: the erectile function trials included men with obesity, high blood pressure, heart disease, and stroke, and benefits appeared across these groups. Women’s studies included participants with antidepressant-related difficulties [2, 6, 7].
Myth: “It’s all about testosterone.” Documented fact: the arousal boost from a single workout occurs without measurable testosterone increases. Blood flow and nervous system mechanisms appear more important [5, 6].
Myth: “Exercise replaces medical care.” Documented fact: erectile difficulties frequently coexist with heart and metabolic conditions, and the trials reviewed studied exercise as a structured intervention, often combined with other lifestyle changes. Persistent sexual problems deserve a medical evaluation [2].
Practical takeaways
The research supports a simple approach. Aim for regular aerobic exercise, roughly 150 minutes per week of moderate activity, spread over three to five sessions, matching the regimens that worked in the trials [2]. Give it weeks to months, since the benefits in studies built gradually [1, 7]. Add strength training for general health, but know that aerobic work carries the strongest evidence for erectile function [2]. If you train for endurance events, watch for warning signs like falling desire, persistent fatigue, or low morning energy, which may signal excessive load [3, 4]. And if you have ongoing sexual difficulties, speak with a health professional rather than relying on exercise alone [2].
The bottom line
Exercise does improve sexual performance for many people, and the effect is real enough to appear in randomized trials, not just anecdotes. Aerobic exercise has the strongest evidence for erectile function, moderate activation seems to help arousal in women, and pelvic floor training shows genuine benefits. The one caution from the data is equally clear. Training should be consistent and moderate, because chronic extreme endurance work is linked to lower, not higher, desire [1, 2, 3, 4].
