The link between exercise and sex life is real but more nuanced than most articles let on. The honest picture: regular physical activity improves cardiovascular function, energy, mood, body image, and the specific muscular and hormonal systems involved in sexual function. The implausible picture, which is what most "best workouts for sex" articles peddle, is that certain magic exercises will dramatically transform your sex life within weeks. The truth is closer to the first version — sustained physical activity over months produces meaningful benefits, and a few specific kinds of training have outsized effect on the relevant systems.
The five workout categories below are chosen because each one addresses a different physiological aspect of sexual function: cardiovascular capacity, pelvic floor strength, hip mobility, posterior chain power, and stress regulation. They aren't ranked because they aren't substitutes — most people would benefit from elements of all five rather than picking one.
One caveat first. If you're experiencing significant sexual dysfunction — erectile difficulties that have come on suddenly, persistent loss of libido, pain during sex — that's a GP conversation rather than a fitness one. Many sexual function issues have underlying medical causes (cardiovascular, hormonal, neurological, side effects of medication, depression, relationship dynamics) that need direct attention. Exercise can be a useful adjunct to medical treatment but isn't a substitute for it when something specific is going wrong.
1. Cardiovascular training (running, cycling, swimming, brisk walking)
The single most important workout category for sexual function, by a substantial margin. Sexual arousal and performance depend heavily on vascular function — the ability of blood vessels to dilate appropriately in response to nervous system signals — and cardiovascular training is the most powerful way to improve vascular health.
The evidence is well-documented in men: regular cardiovascular exercise reduces the risk of erectile dysfunction substantially, and existing mild-to-moderate ED frequently improves with the addition of regular aerobic training. The mechanisms are well-understood and overlap heavily with the mechanisms behind cardiovascular disease prevention — better endothelial function, lower blood pressure, improved insulin sensitivity, reduced systemic inflammation. The same vascular system that protects you from heart attacks is the one that delivers blood flow during arousal.
The evidence in women is less abundant but consistent in the same direction — improved cardiovascular fitness is associated with better arousal response, less sexual dysfunction, and better overall sexual satisfaction. The mechanism appears to be similar: cardiovascular fitness supports the vascular and autonomic responses involved in sexual function across sexes.
Practical: 150 minutes per week of moderate-intensity cardiovascular exercise. Three 30-minute sessions plus some walking. Cycling deserves a note — long-duration cycling on poorly-fitted bikes can compress pelvic nerves and create the opposite problem, so prioritise a good saddle and proper bike fit if cycling is your main activity.
Skip or modify if: Existing cardiovascular condition (work with cardiologist on safe intensities). Significant joint issues (start with cycling or swimming rather than running).
2. Pelvic floor training (Kegels and weighted variations)
The pelvic floor is the group of muscles that forms the base of the core, supports the pelvic organs, and plays a direct role in sexual function — control of arousal in both sexes, orgasm intensity, urinary continence, and (in women particularly) postpartum recovery and prolapse prevention. Pelvic floor training is one of the few interventions with direct evidence for improving sexual function.
The evidence in women is the strongest: pelvic floor exercises reliably improve sexual satisfaction, reduce urinary incontinence, and support postpartum recovery. The evidence in men is also solid, particularly for orgasm control and post-prostatectomy continence. The technique itself is simple but easy to do wrong — many people contract the wrong muscles or hold their breath, neither of which is useful.
Practical: Identify the right muscle (the one you'd use to stop the flow of urine, but only as a one-time identification exercise — don't do Kegels mid-urination, which can cause issues). Contract for 5 seconds, relax for 5 seconds, 10-15 repetitions, 2-3 times a day. Build up to longer holds and more reps. For women particularly, a pelvic-floor physio can teach the technique properly and identify weakness patterns — well worth the appointment.
Skip or modify if: You have pelvic pain conditions (vaginismus, vulvodynia, chronic pelvic pain) — in these cases the pelvic floor is often already too tense, and pelvic floor relaxation work is what's needed instead. Work with a pelvic floor physio.
3. Hip mobility work
The hips are the joint complex most directly involved in sexual position and movement, and they're also the joint complex most degraded by prolonged sitting. Tight hip flexors, weak gluteal muscles, and reduced rotational range together limit the comfortable range of motion available during sex — a structural issue that has nothing to do with libido and everything to do with mechanics.
The work is unglamorous but effective: hip flexor stretches (couch stretch, kneeling hip flexor stretch), glute activation (clamshells, glute bridges), hip rotation mobility (90/90 rotations, pigeon pose), and adductor mobility (frog stretch, deep squat holds). 10-15 minutes a day of hip work over several months produces a noticeably different range of motion and reduces the joint pain and muscular discomfort that can make sex less enjoyable for desk-bound adults.
Practical: Couch stretch (kneeling hip flexor stretch with rear foot elevated against a wall or sofa) for 60 seconds per side, 90/90 hip rotations 10 per side, deep supported squat hold for 60 seconds, glute bridges 15 reps. Daily, or pre-workout as a warm-up. Yoga practice covers much of the same territory if you'd rather do that — see our piece on five simple daily yoga exercises.
Skip or modify if: Hip impingement, hip replacement, or current hip pain — work with a physio rather than freelancing the stretches, since aggressive mobility work can aggravate certain hip pathologies.
4. Posterior chain strength training (deadlifts, squats, hip thrusts)
Strength training in general, and posterior chain training in particular, has effects on sexual function through three channels: hormonal (testosterone optimisation, particularly important for men over 35), muscular (the glutes, hamstrings, and lower back are the prime movers in many sexual positions), and confidence (the body-image effect is real and not trivial).
The hormonal effect is sometimes overhyped — strength training doesn't dramatically elevate testosterone in healthy adults, but it does support optimal levels and prevent the age-related decline that sedentary lifestyles accelerate. The muscular and confidence effects are less measurable but more directly impactful on the actual experience of sex for most people.
Practical: Two strength sessions a week, each including a compound posterior chain exercise (Romanian deadlift, hip thrust, or back squat) for 3-4 sets of 6-10 reps with weight that's challenging by the final reps. Build progressively. If you're new to lifting, work with a coach for the first few weeks to dial in form on the major lifts — back injury from poor deadlift form is the most common preventable lifting injury.
Skip or modify if: Current lower back injury (work with a physio first). New to lifting (start with bodyweight versions and machines before barbell work).
5. Stress-reducing movement (yoga, walking, deliberate slow exercise)
The under-discussed factor in sexual function is the autonomic nervous system. Arousal requires parasympathetic dominance — the "rest and digest" state. Chronic stress and sympathetic activation (the "fight or flight" state of modern overcommitted life) actively inhibits the physiological responses involved in arousal, particularly for women but for men too. The HPA axis and the reproductive axis are interconnected, and chronically elevated cortisol consistently correlates with reduced libido and sexual responsiveness across populations.
Slow, restorative movement — gentle yoga, long walks, breath-focused practices — reduces baseline sympathetic activation in a way that intense exercise does not. For people whose sex life issues are stress-driven (which is a much larger fraction than usually acknowledged), this category of movement is more therapeutically useful than another HIIT session. The intense workouts are good for cardiovascular health; the slow workouts are good for nervous-system regulation. Both belong in the picture.
Practical: A weekly gentle yoga class, a long walk (45+ minutes) several times a week without a phone or podcast, brief daily breathing practice. The point is to actively cultivate parasympathetic time, not just to assume it will happen on its own.
Skip or modify if: You're already over-trained or fatigued (in which case slow movement is doubly important; intense training is what to skip).
Where this leaves you
The five categories above aren't a workout programme — they're five different angles on the same underlying picture, and most people would benefit from elements of all of them. A reasonable weekly structure might look like: three cardiovascular sessions, two strength sessions including posterior chain work, daily hip mobility and pelvic floor work as 10-15 minute add-ons, and one longer gentle-movement session like a yoga class or long walk. That's a substantial commitment, but it's also a substantial intervention into health more broadly, of which sexual function is one downstream effect.
The honest framing on timeline: cardiovascular changes that meaningfully affect vascular function take 8-12 weeks of consistent training. Pelvic floor changes can show up in 4-6 weeks of regular daily practice. Hip mobility changes are similar — 6-8 weeks of daily work. Strength training and the associated hormonal optimisations are 3-6 months. None of this is fast, and articles that promise faster results are overstating the timeline.
For the wider context on sustainable training and the lifestyle factors that compound with it, our pieces on why running is good for you and 8 exercises to lose weight cover the cardiovascular and structural-training sides. The health and wellness archive covers the broader rest, recovery, and stress-management picture that supports all of this.
