Aerobic exercise is the most well-studied and broadly effective exercise for erectile dysfunction, with clinical trials showing improvements after 30 to 60 minutes of moderate-to-vigorous activity, three to five times per week. But it’s not the only type that helps. Pelvic floor training and yoga both show meaningful benefits, and the best approach for you likely combines more than one.
Why Exercise Helps Erections
An erection depends on blood flow. When you’re aroused, blood vessels in the penis need to relax and widen to let blood rush in. That process relies on a molecule called nitric oxide, which is produced by the cells lining your blood vessels. In men with ED, those cells often don’t produce enough of it.
Exercise fixes this at a biological level. When your heart rate goes up, blood moves faster through your arteries, creating physical friction along the vessel walls. That friction triggers your body to produce more nitric oxide, both during the workout and at rest over time. Research published in Circulation found that regular exercise has a dual effect: it increases the amount of nitric oxide-producing machinery in your blood vessels and makes that machinery work more efficiently. The result is better blood flow everywhere, including to the penis.
There’s also a hormonal component. Exercise, particularly when it leads to fat loss, raises testosterone levels. And it lowers stress hormones and improves sleep, both of which matter for sexual function.
Aerobic Exercise: The Strongest Evidence
Most clinical trials on exercise and ED have tested aerobic activity: brisk walking, jogging, cycling, swimming, or using an elliptical. The typical protocol involves 30 to 60 minute sessions, three to five times per week, for around six months. Moderate to high intensity is what matters here. A casual stroll won’t generate the blood flow changes your vessels need.
A meta-analysis of randomized controlled trials found that aerobic exercise was significantly better than no exercise for improving erectile function scores, with greater gains in men who had worse ED at baseline. That said, the magnitude of improvement was modest. The gains were most clinically meaningful for men with mild ED. For moderate or severe cases, aerobic exercise alone may not be sufficient, but it still helps and pairs well with other treatments.
One trial focused specifically on abdominally obese, sedentary men illustrates the dose-response relationship. Men who exercised 200 to 300 minutes per week for 24 weeks saw their erectile function scores improve by 2.6 points, lost nearly 6 kilograms, and dropped about 5 centimeters from their waist. Men who exercised less than 150 minutes per week improved by only 1.8 points and lost less weight. The higher-volume group also had a significantly greater increase in testosterone. More exercise meant better results across the board.
How Much Fat Loss Matters
Abdominal fat is independently linked to ED, separate from overall body weight. Belly fat increases inflammation, disrupts hormone balance, and damages blood vessel function. In the same trial of obese men, the group that exercised more lost over four times as much body fat (about 4.7 kilograms compared to 1.1 kilograms) and saw correspondingly better erectile function. If you’re carrying excess weight around your midsection, the exercise-driven fat loss may be just as important as the direct vascular benefits of working out.
Pelvic Floor Exercises
Your pelvic floor muscles play a direct role in erections. They help trap blood inside the penis and maintain rigidity. When these muscles are weak, blood can leak out faster than it flows in, making erections difficult to sustain.
Pelvic floor training, often called Kegels, involves repeatedly contracting and relaxing the muscles you’d use to stop urinating midstream. A systematic review of trials found that pelvic floor training improved both erectile function and ejaculatory control across all studies that measured it. Men in these trials generally practiced daily, often starting with a few sets of 10 contractions and building up over weeks.
No single optimal protocol has been identified yet, as training programs varied widely across studies. But the consistent finding is that it works. You can expect to notice changes in about four to six weeks of daily practice. The exercises are free, can be done anywhere without anyone knowing, and have no side effects.
Pelvic floor training is also specifically recommended for men recovering from prostate surgery. Even with nerve-sparing techniques, full erectile function can take six months to two years to return after a prostatectomy. Starting Kegels in the weeks before surgery and resuming them about a week afterward (once a catheter is removed) helps increase blood flow to the area and supports recovery.
Yoga for Stress-Related ED
Erections require your nervous system to shift into a relaxed state. Stress, anxiety, and performance pressure activate your fight-or-flight response, which constricts blood vessels and directly works against the process of getting hard. If your ED has a psychological component, or if you notice it’s worse during stressful periods, yoga may be particularly useful.
A study of 65 men aged 24 to 60 found that 12 weeks of regular yoga sessions significantly improved sexual function scores across every domain measured: desire, erection quality, ejaculatory control, orgasm, confidence, and satisfaction with a partner. The improvements were statistically significant. Yoga combines physical movement, controlled breathing, and mental focus in a way that reduces baseline stress levels and improves body awareness, both of which feed into sexual response.
Yoga isn’t a replacement for aerobic exercise if your ED is driven by poor cardiovascular health or obesity. But as a complement, it addresses a dimension of sexual function that running on a treadmill doesn’t.
A Practical Exercise Plan
The research points toward a combination approach. Here’s what that looks like in practice:
- Aerobic exercise: 150 to 300 minutes per week of moderate-to-vigorous activity. Brisk walking counts if your heart rate is elevated. Running, cycling, swimming, or rowing are all effective. More minutes per week correlates with better results.
- Pelvic floor training: Daily Kegel exercises. Contract the muscles for 5 seconds, relax for 5 seconds, repeat 10 to 15 times. Do two to three sets throughout the day. Gradually increase hold times as you get stronger.
- Yoga or stretching: One to two sessions per week, especially if stress or anxiety plays a role. Even 20 to 30 minutes of focused breathing and movement can lower baseline tension.
How Long Before You See Results
Pelvic floor exercises tend to produce noticeable changes in four to six weeks. Aerobic exercise takes longer. Most clinical trials ran for three to six months before measuring outcomes, and the best results came at the six-month mark. This isn’t a quick fix. It’s a gradual process of improving blood vessel health, building pelvic muscle strength, and (if relevant) losing abdominal fat.
The improvements are also dose-dependent. Men who exercised more consistently and at higher volumes saw better erectile function scores, more fat loss, and greater testosterone increases than those who did the minimum. Treating exercise like a prescription, with a specific weekly target you track, produces better results than vaguely “being more active.”
For men with mild ED, exercise alone may be enough to restore normal function. For moderate or severe ED, exercise is best viewed as one part of a broader approach that might include medication or other interventions. But regardless of severity, regular physical activity improves the underlying vascular and hormonal conditions that contribute to the problem.
