Exercise is one of the most powerful lifestyle interventions for erectile dysfunction — and the evidence for this is considerably stronger than most men realise. The key question is: what type of exercise, and how much, and does it work for all types of ED?

Cardiovascular Exercise and Penile Blood Flow

The mechanism is straightforward: aerobic exercise improves endothelial function — the health of the cells lining blood vessels — and promotes nitric oxide production, which is the key signalling molecule for penile artery dilation during erection. A 2018 meta-analysis in the Journal of Sexual Medicine found that aerobic exercise significantly improved erectile function in men with ED across multiple studies, with the strongest effects in those with vasculogenic and metabolic-related ED.

The minimum effective dose appears to be around 40 minutes of moderate-to-vigorous aerobic exercise, 4 times per week. This is meaningful — casual walking or light activity doesn’t appear to produce the same cardiovascular improvements in blood vessel responsiveness.

Pelvic Floor Training

Pelvic floor (Kegel) exercises for men have specific evidence in ED. The pelvic floor muscles play a direct mechanical role in erections — the ischiocavernosus and bulbospongiosus muscles contribute to maintaining erection rigidity and achieving full engorgement. A randomised controlled trial found that regular pelvic floor training produced greater improvements in erectile function than PDE5 inhibitors alone in some patient groups.

Resistance Training and Testosterone

Compound resistance training — squats, deadlifts, and presses — produces acute and chronic increases in testosterone, which supports libido, morning erections, and overall sexual motivation. For men whose ED has a hormonal component (covered in our guide to testosterone and sexual performance), resistance training addresses both the hormonal and vascular dimensions simultaneously.

What Exercise Cannot Fix Alone

Exercise is powerful but has limits. In men with established vascular pathology — narrowed penile arteries from atherosclerosis — lifestyle exercise may improve the situation but is unlikely to fully restore function. This is where treatments that directly address the vascular structure, such as focused shockwave therapy for erectile dysfunction, fill an important gap that exercise alone cannot close.

The most rational approach for men with vascular ED is to combine regular aerobic and resistance exercise with targeted vascular treatment — using each where it’s most effective.

The Sleep Connection

One often-missed benefit of consistent exercise is sleep quality improvement, which feeds back into testosterone production and recovery. Men who struggle with both hormonal health and sleep should read our guide on male hormone health and sleep to understand why this chain of effects matters.
