Vaginal Muscles: What They Are and How to Train

Ask most people where their vaginal muscles are and they point somewhere vague between the hips. That vagueness is the problem. The muscles people call the vaginal muscles are part of the pelvic floor, and how well they work decides whether you leak when you sneeze, whether sex feels like much, and how well your organs stay where they belong.

They are also trainable. Not with a gadget or a supplement, but with the same principle that builds any other muscle: a specific contraction, done regularly, with progression.

What the vaginal muscles actually are

There are two different kinds of muscle in play, and confusing them is why so much advice misses.

The vaginal wall itself is smooth muscle. It is involuntary, like the muscle in your gut. You cannot squeeze it on command, and no exercise programme targets it directly.

The muscles you can train wrap around the vaginal opening and the canal. The main one is the levator ani, a broad sling that Cleveland Clinic describes as the bulk of the pelvic floor. It has three parts:

• Pubococcygeus — runs from the pubic bone back toward the tailbone and sits closest to the vaginal opening
• Puborectalis — loops behind the rectum like a sling and controls bowel continence
• Iliococcygeus — the broader, flatter back portion that provides support from underneath

Alongside them sits the bulbospongiosus, which encircles the vaginal opening and contracts rhythmically during orgasm, plus the urethral and anal sphincters.

Together these muscles do three jobs: they hold the bladder, uterus and rectum up against gravity and pressure, they close the urethra and anus so nothing escapes when you cough or lift, and they contribute to sexual sensation and orgasm. A review of pelvic floor anatomy and applied physiology in Gastroenterology Clinics of North America frames it exactly that way — support plus a continence mechanism for the urethral, anal and vaginal openings.

Why tone matters more than raw strength

The common assumption is that pelvic floor problems mean weak muscles. Often they do. But the pelvic floor can also be too tight, and the symptoms overlap enough that people train the wrong direction for months.

A weak pelvic floor struggles to resist pressure. You get leaking with a cough, sneeze, laugh or jump, a heavy dragging sensation, reduced grip during sex, and in more advanced cases, prolapse. The NHS notes that pelvic organ prolapse happens when the tissues supporting the pelvic organs weaken and stretch, often after childbirth.

An overactive pelvic floor never fully lets go. That shows up as pain with penetration, trouble inserting a tampon, a slow or stop-start urine stream, urgency, and aching in the pelvis or low back. Persistent, involuntary tightening of the muscles around the vaginal opening is the mechanism behind vaginismus, which the NHS describes as the body's automatic reaction to the fear of penetration.

This is the single most important thing to get right before you start training. Squeezing a muscle that is already clenched makes symptoms worse, not better. Our guide on how to tell if your pelvic floor is tight or weak walks through the self-checks, and how to relax pelvic floor muscles covers the down-training side.

What the evidence says about training them

Pelvic floor muscle training is not fringe advice. It is first-line clinical treatment, and the evidence behind it is unusually solid for a conservative therapy.

A Cochrane systematic review pooled 31 trials covering 1,817 women across 14 countries. Women doing pelvic floor muscle training were substantially more likely to report cure or improvement in their incontinence than women who got no treatment or an inactive control, with fewer leakage episodes and better quality-of-life scores. The reviewers concluded it should be part of first-line conservative management.

The sexual function side is less mature but points the same way. A narrative review of female sexual function and pelvic floor muscle training found a positive association between pelvic floor muscle strength and sexual function scores, with the clearest effects in women who also had stress urinary incontinence or prolapse. The honest summary: training reliably helps continence, and often helps sensation and confidence alongside it.

Both effects come from the same place. Stronger, better-coordinated muscles close the urethra faster under pressure and generate more force during orgasmic contractions. It is the same mechanism in men, where the pelvic floor muscles at the base of the penis raise pressure inside the erectile chambers — the reason pelvic floor muscles matter for erection quality too.

How to train the vaginal muscles properly

Technique first. Volume second. Most people who say kegels did nothing were bearing down, holding their breath, or squeezing their glutes.

Find the right contraction

1. Lie on your back with knees bent, or sit upright on a firm chair.
2. Imagine stopping the flow of urine and holding back wind at the same time. That double cue recruits the front and back of the sling.
3. You should feel a lift and squeeze inward and upward. Your belly, buttocks and thighs should stay still.
4. Rest a hand on your lower abdomen. If it pushes out, you are bearing down — the opposite of what you want.
5. Breathe normally throughout. Holding your breath raises abdominal pressure and works against you.

Do not test this by actually stopping your urine mid-stream more than once. Used as a repeated exercise it can interfere with bladder emptying.

The weekly routine

Pelvic floor muscles have both slow-twitch fibres for endurance and fast-twitch fibres for the sudden clamp-down when you sneeze. Train both.

1. Long holds — squeeze and lift, hold 5 seconds, relax fully for 5 seconds. Build to 10 seconds as you get stronger. Do 10 reps.
2. Quick flicks — sharp, one-second squeezes with a full release between. Do 10 reps.
3. Repeat the set three times a day, in line with the NHS guidance on urinary incontinence and the Harvard Health step-by-step guide.
4. Relax completely between reps. The release is half the exercise. A muscle that never lets go does not get stronger, it gets tired.
5. Add the knack — a deliberate squeeze just before you cough, sneeze or lift something. This is where strength turns into fewer leaks.

The whole thing takes under five minutes. The hard part is not difficulty, it is remembering to do it three times a day for three months.

What progress actually looks like

Clinical trials typically run for at least three months before measuring outcomes, and that is the timeline to plan around.

• Weeks 1-2 — you get better at isolating the contraction. Nothing feels different yet.
• Weeks 3-6 — holds get longer and steadier. Many people notice fewer small leaks first.
• Weeks 6-12 — measurable strength gains. Better control during coughing and exercise, often more sensation during sex.
• Beyond 12 weeks — continued improvement, but only if you keep training. Pelvic floor strength detrains like any other muscle when you stop.

If you have had no change at all after eight weeks of honest daily practice, that usually means the technique is off or the underlying problem is tightness rather than weakness. That is a signal to get assessed, not to squeeze harder.

When to get help rather than train harder

See a doctor or pelvic health physiotherapist if you have:

• Pain with penetration, tampons or a pelvic exam — strengthening is likely the wrong direction
• A bulge, pressure or dragging sensation in the vagina, which can indicate prolapse
• Leaking that does not improve after three months of consistent, correct training
• Difficulty emptying your bladder or bowel completely
• Ongoing pelvic pain with no clear cause

The NIDDK notes that bladder control problems are common and treatable, and that many women wait years before mentioning them. There is nothing to gain from waiting. For more on what leaking means and what to do about it, see our guide to urine leakage in females.

The bottom line

The vaginal muscles worth training are the pelvic floor muscles that wrap around the vaginal opening — mainly the levator ani and the bulbospongiosus. Cochrane evidence from 31 trials shows that training them is a genuine first-line treatment for incontinence, and the same strength gains tend to improve sensation and confidence.

Get the direction right first: strengthen a weak floor, release a tight one. Then train the contraction properly, three short sets a day, and give it twelve weeks before you judge the result.
