How to Do a Pelvic Floor Contraction Correctly

A correct pelvic floor contraction is a squeeze around the openings combined with a lift inwards and upwards, held briefly and then fully released, with no bearing down, no breath holding and no substitute effort from the buttocks, inner thighs or abdominal wall. The research definition of an ideal effort is a significant increase in urethral closure force without appreciable bearing down¹, which is the same instruction in laboratory language. This page explains what the movement is and why it is easy to get wrong. It does not prescribe a programme, because a dose belongs to an assessment.

I had been doing them for eleven years before anybody checked. I am a PE teacher, I coach teenagers through movements they cannot see themselves perform every working day, and I still had it wrong: when my pelvic floor was finally measured, the first thing the physiotherapist said was that I was gripping my glutes and pushing my breath down at the same time. I had been diligent about the wrong thing for over a decade. Before anything else on this site, please read red flags and when to stop and get checked, because a small number of symptoms need a doctor rather than a technique.

What a correct contraction actually is

A single co-ordinated action with three components: a closing squeeze around the urethra, vagina and anus, an inward and upward lift, and then a complete release back to resting length. All three matter. A contraction that closes but never lifts is partial, and a contraction that never fully releases is the beginning of a different problem.

The measurable version of that description comes from the study that established the whole issue. An ideal effort was defined as a significant increase in urethral closure force without appreciable bearing down, and it was assessed instrumentally rather than by asking the woman whether she thought she had done it¹. That distinction between what a movement feels like and what it does is the reason this article exists.

The International Urogynecological Association publishes patient-facing material describing the same muscles and their job for people who want the anatomy in plain terms². For the structural version on this site, see what is the pelvic floor.

What the incorrect versions look like

There are four common ones, and only one of them is simply doing nothing.

• Bearing down. The effort goes outwards and downwards instead of inwards and up. This is the version that matters most, because it loads the structures the programme is meant to support.
• Substitution. The buttocks, inner thighs or abdominal wall do the visible work while the pelvic floor stays largely uninvolved. It feels like effort, which is exactly why it is convincing.
• Breath holding. Bracing the breath produces a sensation of tension throughout the trunk that is easily mistaken for a contraction.
• Never releasing. Holding a low-grade squeeze all day is not a training effect. It is the fast route to the presentation covered in hypertonic pelvic floor and downtraining.

How often people get it wrong, with both halves of the number

Here is the pairing this site never separates. In 47 women referred for urodynamic evaluation of urinary incontinence, only 23 of them, 49%, achieved an ideal contraction after brief standardised verbal instruction, and 12, or 25%, performed a technique that could potentially promote incontinence¹. In 779 women attending community-based primary care practices, correct contraction on the first attempt ranged from 68.6% in women with both prolapse and stress incontinence to 85.8% in women with neither, and of the 120 who contracted incorrectly at first, 94, or 78%, learned after brief instruction³.

Those two results are not in conflict and the difference between them is the denominator. Bump studied 47 women already referred with a problem, in 1991. Henderson studied 779 women walking into ordinary primary care. So “half of all women cannot do a pelvic floor contraction” is a misreading that this site treats as banned, and the defensible claim is narrower and more useful: a meaningful minority get it wrong, most of those learn quickly once someone shows them, and the error rate is highest exactly among the people who already have symptoms and are therefore reading this page.

Why verbal instruction alone is not enough

Because the people who ran the study said so, in the paper’s own conclusion: simple verbal or written instruction does not represent adequate preparation for a patient about to start a programme¹. A wider review of the field puts the same point positively, stating that pelvic floor muscle training needs proper instruction and close follow-up to be effective, and that supervised and more intensive training is more effective than unsupervised training⁴.

I want to be blunt about what that means for an article like this one. Reading a description of a movement is a weaker intervention than the brief verbal instruction that already failed a quarter of the women in the 1991 study. This page can tell you what the target is. It cannot tell you whether you hit it.

What the guideline means by supervised

It means a named professional with expertise, not a leaflet. NICE NG210 recommendation 1.3.15 states that programmes should be supervised by a physiotherapist or other healthcare professional with the appropriate expertise in pelvic floor muscle training, and recommendation 1.6.18 requires at least one review to assess progress during the programme and one review at the end of it⁵. Both of those only mean something if somebody established what was being reviewed in the first place.

That is also where the treatment effect in the trials comes from. The Cochrane review that produced the strongest number in this field, cure in 56% of women with stress urinary incontinence against 6% of controls, a risk ratio of 8.38 with a 95% confidence interval of 3.68 to 19.07 from 4 trials and 165 women, graded high certainty, was pooling trials of taught and supervised training rather than of self-directed effort⁶. The instruction is not an optional wrapper around the exercise. It is part of what was tested.

Why this page gives you no dose

Because a dose is a clinical decision made against an assessment, and prescribing one here would be pretending the assessment happened.

NICE NG123 does state a floor: programmes should comprise at least 8 contractions performed 3 times per day⁷. Read the tag before you treat that as a personal instruction. That recommendation is marked 2006 in the guideline, meaning it was carried forward unchanged from the previous guidance and was not re-reviewed in the 2019 update. It is a minimum specification for a programme, not a prescription for a person, and how hold length, repetition count, fast contractions, position and load are actually set and progressed is the subject of pelvic floor exercise programmes explained.

How the contraction gets checked

By someone who can feel or measure it. In practice that means an examination, a pressure sensor, surface electromyography or ultrasound, chosen by the service and by what you consent to. What each of those adds, and what it does not, is covered in biofeedback and electrical stimulation, and the examination itself, including how to decline it and still be treated, is covered in internal pelvic examination what to expect.

The moment it changed for me was not a strength measurement. It was watching a number fail to move while I was absolutely certain I was doing something. I have thought since that the useful thing a sensor gave me was not motivation, it was disproof.

When the contraction is not the problem

Sometimes the muscle is not failing to switch on, it is failing to switch off, and then every instruction on this page is the wrong instruction. Symptoms can look similar from the outside: urgency, pain, incomplete emptying, discomfort with sex. The treatment runs in the opposite direction, and conventional strengthening can make it worse.

That is the single reason a website cannot substitute for an assessment and it is why hypertonic pelvic floor and downtraining is linked from every strengthening page here. If your symptoms are worse after four weeks of diligent effort, the answer is a reassessment, not more repetitions.

If you cannot feel anything at all

That is common enough to be unremarkable and it is not a verdict on your prospects. A muscle you have never consciously used is a muscle you have never learned to find, and the 2013 primary care study is encouraging on precisely this point: 78% of the women who contracted incorrectly at first attempt learned after brief instruction³.

It is also worth keeping the scale of the underlying problem in view. Population studies put any urinary incontinence in women at roughly 25% to 45% depending on the definition used, with more than 40% of women aged 70 and over affected⁸. This is an extremely common problem with a first-line treatment that has good evidence behind it, and the first step is not effort. It is assessment: see what happens at a pelvic health physio assessment, pelvic floor physiotherapy for the treatment in full, and questions to ask at your first appointment for how to make sure your technique gets checked rather than assumed.
