How to Use Kegel Balls: What They Do and What They Do Not

Updated October 2026

Kegel balls get sold on a promise that runs roughly: insert these, go about your day, come back tighter and with better orgasms. That is not what the research says, and the real answer is more useful than the sales pitch.

Here is what they actually do, what the evidence actually shows, how to use them properly, and how to pick a first set without wasting money on the wrong weight.

What Kegel Balls Actually Do

Two separate questions get mashed together here, and they have different answers.

Does pelvic floor training work? Yes, and the evidence is strong.

A Cochrane review pooled 31 trials covering 1,817 women across 14 countries. Among women doing supervised pelvic floor muscle training, 74% reported cure or improvement of stress urinary incontinence against 11% of controls – a risk ratio of 6.33, rated moderate certainty. For symptomatic cure on its own the certainty was rated high. The reviewers’ own words: they “can be confident that PFMT can cure or improve symptoms” of stress incontinence, and that it belongs in first-line treatment.

That is about as solid as this kind of evidence gets. Training the pelvic floor works.

Do the balls make it work better? No – they make it the same.

This is the part nobody selling them mentions. A separate Cochrane review looked specifically at weighted vaginal cones and balls: 23 trials, 1,806 women, 717 of them using weights.

• Weights beat doing nothing. Risk ratio for failure to cure 0.84 (95% CI 0.76 to 0.94).
• Weights versus plain exercises: no meaningful difference. Risk ratio 1.01 (95% CI 0.91 to 1.13).
• The reviewers’ conclusion: cones “could be offered as one treatment option, if women find them acceptable” – and they flagged that this stays tentative until larger, better trials are done.

So weighted balls are a way of doing the exercise, not an upgrade to it. Someone squeezing on a schedule with nothing inserted gets about the same result as someone using a $40 set.

Then Why Buy Them At All?

Because “about the same result” assumes you actually do the exercises, and most people do not.

Kegels are easy to skip and easy to do wrong – plenty of people squeeze their glutes or hold their breath and think they are training the right muscle. A weighted ball fixes both problems in a mundane way: it is a physical cue that you are meant to be doing this, and you can feel whether you are gripping it or not. That feedback is the actual product.

Worth knowing the flip side, though, because the same review found it: dropout rates in the weights groups were high, and some women simply find them unpleasant or awkward to use. If that turns out to be you, the exercises on their own are not a lesser option – they are the thing the balls were helping you do.

How to Use Kegel Balls

1. Empty your bladder first. Not a rule so much as a comfort thing, and it makes the sensation easier to read.
2. Use water-based lubricant. A small amount on the ball, not a lot – too much and it will not stay put. Water-based is the safe default across silicone, glass and steel alike.
3. Insert while relaxed, lying down or with one leg raised. Push gently until the ball sits past the pelvic floor muscle, roughly a finger-length in. The retrieval cord, if there is one, stays outside.
4. Find the right muscle. Squeeze as though you were stopping yourself mid-stream. You should feel a lift, not a clench – your stomach, thighs and buttocks should stay still. If they are moving, you are using the wrong muscles.
5. Work in sessions, not all day. Squeeze and hold for three to five seconds, release fully for the same, and repeat ten times – two or three sets. The release matters as much as the squeeze.
6. Remove by bearing down gently and drawing the cord out, or by squatting slightly and pushing if there is no cord. Wash before and after every use.

Two protocols, both legitimate. Active sets are the one above – squeeze, hold, release. Passive retention is the other: insert, then simply hold them in while you move around for 15 to 20 minutes, which is closer to what the weighted-cone trials actually tested. Either works. What does not work is wearing them all day, which fatigues the muscle rather than strengthening it – a muscle trains in sessions and recovers in between, same as any other.

How Long Before Anything Changes

Four to six weeks of consistent daily sets before you notice a difference, and around three months for the kind of change that shows up in a clinical measurement. The trials in both Cochrane reviews mostly ran on that timescale.

If you have done eight weeks properly and felt nothing at all, that is worth a conversation with a pelvic floor physiotherapist rather than a heavier ball. Weakness is not the only reason a pelvic floor misbehaves – an over-tight pelvic floor produces some of the same symptoms and gets worse with more squeezing, which is precisely the case where buying a heavier set makes things worse.

Choosing a First Set

Start lighter than you think. The common mistake is buying heavy, failing to hold it, and concluding the whole thing does not work. If it drops, it is too heavy – you want something you can hold comfortably through a full set.

Progressive sets are the sensible buy. A system with interchangeable weights means one purchase covers the whole progression instead of three. There is a training system here with nine weight combinations and printed instructions in the box, which is about as much hand-holding as this category offers.

Material is mostly about weight and cleaning. Silicone is light and forgiving, and the usual starting point – a beginner duo set is the low-commitment version. Glass and steel are heavier for their size and nonporous, so they clean properly and last indefinitely. The Cloud 9 borosilicate glass set pairs glass balls with a silicone sleeve and a retrieval tether, which is the combination worth having if you want the weighted feel without the retrieval anxiety. For heavier still, Sportsheets’ steel kegel balls are a step up in weight – and worth noting they have no tether, so they suit someone already confident with removal.

Decide about the cord before you buy. A retrieval cord is the single feature most likely to determine whether a nervous first-timer actually uses the thing. Ben wa balls on a string are the plainest version. Cordless balls are not dangerous – the vagina is a closed space and nothing goes missing – but “I know I can get it out” matters more than it sounds.

Vibration is optional and not part of the training. A rechargeable vibrating ball is two tools in one – it has a retrieval cord and a submersible rating, and twelve patterns that have nothing to do with your pelvic floor. That is a pleasure feature sitting on top of an exercise tool. Nothing wrong with it, but it is not what makes the exercise work, and it is not worth paying extra for if training is the only reason you are here.

What They Will Not Do

They will not “tighten” you in the way the word implies. What training changes is muscle tone and control – your ability to contract deliberately and hold it. It does not shrink anything. Tone and tightness are different things, and the marketing deliberately blurs them.

They are not a guaranteed route to better orgasms. The claim is everywhere and it is not baseless – the pelvic floor is involved in orgasm, so improving its control plausibly affects sensation. But the evidence for sexual function is substantially thinner and less consistent than the incontinence evidence above, and anyone quoting you a percentage on it is making it up. Treat better orgasms as a possible bonus, not the reason to buy.

They will not fix a prolapse or replace a physiotherapist. Pelvic floor physiotherapy is a real clinical speciality and it is the right answer for prolapse, persistent pain, or incontinence that is not improving.

Common Questions

How do you use kegel balls?
Apply a little water-based lubricant, insert while relaxed until the ball sits past the pelvic floor muscle, then squeeze as though stopping yourself mid-stream – holding three to five seconds, releasing fully for the same, ten reps, two or three sets. Your stomach, thighs and buttocks should stay still. Remove by bearing down gently and drawing the cord out, and wash before and after every use.

Do kegel balls actually work?
Pelvic floor training works, and the evidence is strong – a Cochrane review of 31 trials and 1,817 women found 74% of women reported cure or improvement of stress incontinence against 11% of controls. But a separate Cochrane review of 23 trials and 1,806 women found weighted balls perform about the same as doing the exercises with nothing inserted. The balls are a way of doing the exercise, not an upgrade to it – their real value is that they make you more likely to actually do it.

How long should you leave kegel balls in?
Work in sets rather than wearing them for hours. Ten squeezes of three to five seconds, two or three sets, is a session. Wearing them all day is a marketing idea, not a training method, and it tends to fatigue the muscle rather than strengthen it.

How long until I notice a difference?
Four to six weeks of consistent daily sets for a noticeable change, and about three months for the kind measurable in a clinic. If eight weeks of proper use changes nothing, see a pelvic floor physiotherapist rather than buying something heavier.

Can kegel balls get lost inside you?
No. The vagina is a closed space, so nothing can travel beyond reach. Bearing down gently, or squatting slightly and pushing, brings them within reach. This is also why loose balls are strictly for vaginal use – the rectum is not closed, so loose balls must never be used anally.

What weight should a beginner start with?
Lighter than feels impressive. If a ball drops during a set, it is too heavy and you will train less, not more. A progressive set with interchangeable weights is the economical way to move up as you get stronger.
