A Kegel trainer or pelvic floor exerciser can add resistance, guidance or feedback to pelvic floor muscle training. The right choice depends on what you want help with, whether your pelvic floor needs strengthening and what type of device you will use comfortably and consistently.
You do not need a device to exercise your pelvic floor. If you can already contract and fully relax the correct muscles, a well-structured exercise programme may be all you need. Research suggests that adding biofeedback to pelvic floor muscle training makes little or no difference to several urinary incontinence outcomes on average, although some people value the guidance, motivation and reassurance it provides.
Pelvic floor symptoms do not always mean that the muscles are weak. Painful penetration, pelvic pain, urinary urgency, constipation and difficulty relaxing may be associated with a tight or overactive pelvic floor. In that situation, adding resistance or doing more contractions may make symptoms worse.
Key takeaways
- Kegel exercises are one part of broader pelvic floor muscle training.
- A trainer is an optional aid, not a requirement or a substitute for assessment.
- Weighted trainers add resistance but do not confirm that you are using the correct muscles.
- Sensor-guided devices can adjust or prompt a session, while app-based biofeedback can display information about your contractions.
- An app-controlled vibrating device is not automatically a biofeedback device.
- More weight, more squeezing and more repetitions are not necessarily better.
- The pelvic floor needs to contract when appropriate and relax fully afterwards.
- Seek professional advice before strengthening if you have pain, difficulty relaxing, bladder or bowel emptying problems or significant prolapse symptoms.
What is a Kegel trainer?
A Kegel trainer is a device designed to assist pelvic floor muscle exercise. Depending on its design, it may add resistance, guide the timing of contractions, detect aspects of muscle activity or provide visual feedback.
“Kegel” generally refers to voluntarily contracting and lifting the pelvic floor muscles. Pelvic floor muscle training is broader. It may involve strength, endurance, quick contractions, coordination, functional bracing and learning to relax the muscles completely.
The products compared in this guide are designed for vaginal insertion. Pelvic floor muscle training can also be relevant to people who do not use vaginal devices, but these particular trainers will not suit every body or every pelvic health concern.
Do you need a Kegel trainer?
No. You can perform pelvic floor muscle training without a device.
A trainer may be useful if you want:
- a structured routine
- resistance during deliberate exercises
- prompts showing when to contract and relax
- feedback about your contractions
- progress tracking
- additional motivation to practise regularly
A device is less useful if you are contracting the wrong muscles, holding your breath, bearing down instead of lifting or failing to relax between contractions. If you cannot confidently identify a pelvic floor contraction, professional guidance is a better starting point than buying a heavier or more advanced trainer.

What types of Kegel trainers are available?
| Trainer type | How it works | What it may help with | What it does not do |
|---|---|---|---|
| Weighted resistance trainer | Adds weight or resistance during deliberate pelvic floor exercise. Some contain an inner ball that moves with your body. | Simple resistance-based training when you already understand the correct technique. | It does not measure the contraction or confirm that you are lifting rather than bearing down. |
| Sensor-guided trainer | Detects aspects of your contraction and uses vibration or another signal to guide or adapt the routine. | Structured sessions without necessarily needing to look at a phone. | Not every device provides detailed real-time data or a visual display. |
| App-based biofeedback trainer | Uses sensors and an app to display information about pelvic floor movement, exercise performance or progress. | Visual guidance, tracking, reminders and motivation. | It does not diagnose the cause of symptoms or replace a professional assessment. |
| Vibrating or remotely controlled exerciser | Provides vibration, sensation or timed prompts through buttons, a remote or an app. | Awareness, prompts or a more sensory training experience. | Unless the product contains contraction sensors, vibration or app control is not biofeedback. |
| Electrical stimulation device | Uses an electrical current to stimulate muscle activity. | Specific circumstances in which a healthcare professional recommends stimulation. | It is different from biofeedback and is not a routine requirement for pelvic floor training. |
Some devices combine more than one function. Always check whether a product actually measures contractions rather than assuming that “smart”, vibrating or app-connected means biofeedback.
Which type of Kegel trainer may suit you?
| What you want | Consider | Why |
|---|---|---|
| A simple, lower-cost resistance tool | A weighted ball, egg, bead or cone | No charging or app is required, but you need to understand the correct contraction and relaxation technique. |
| A guided routine without using your phone | A sensor-guided trainer such as KegelSmart 2 or LELO Smart Bead | The device guides or adapts the exercise through vibration. |
| Real-time visual feedback and progress tracking | Elvie Trainer | The connected app displays pelvic floor movement and guides exercises. |
| Vibration or a sensory prompt | Calexotics Connect or Niya N1 | These provide vibration control but their current product descriptions do not state that they measure contractions. |
| Help identifying the muscles or knowing whether you need strengthening | A pelvic health physiotherapist first | An assessment can distinguish weakness from overactivity, poor coordination or another cause of symptoms. |
Smart, sensor-guided and vibrating trainer comparison
| Product | Training method | App or control | Feedback and guidance | May suit someone who |
|---|---|---|---|---|
| Elvie Trainer | Sensor-based biofeedback | Smartphone app required | Real-time visual guidance, structured exercises, levels, goals and progress tracking | wants detailed visual feedback and is comfortable training with an app |
| Intimina KegelSmart 2 | Sensor-guided vibration programme | No app required | Registers pelvic floor response, selects a level and guides a short routine using vibration | wants adaptive guidance without looking at a screen |
| LELO Smart Bead | Touch-sensor and vibration guidance | No app required | Responds to squeezing, adapts to performance and provides progressive vibration levels | wants a compact sensor-guided device without an app |
| Calexotics Connect Kegel Exerciser | Vibrating exerciser | App or push-button control | Multiple vibration, pulsation and escalation patterns; no contraction measurement stated | wants vibration and app control rather than measured biofeedback |
| Niya N1 Kegel Massager | Dual-motor vibrating trainer and massager | Remote control | Vibration and external stimulation; no contraction measurement stated | wants a sensory device with internal and external vibration |
Remember: Sensor-based feedback, vibration guidance and remote control are different functions. Choose the function you will genuinely use rather than the product with the most technology.
Weighted Kegel trainer comparison
Weighted trainers vary in weight, diameter, length, shape and progression method. A heavier trainer is not always more advanced. Some sets progress by increasing weight, while others use a smaller diameter or a different shape to make retention more challenging.
| Product | Format | Weight options | Useful distinction |
|---|---|---|---|
| Ruby Weighted Kegel Trainer | Single trainer, 30 mm diameter | 55 g | A straightforward single-weight option with a retrieval cord |
| Calexotics Weighted Kegel Balls | Double-ball trainer with moving inner balls | 67 g total | Movement creates sensation and awareness rather than measured feedback |
| Intimina Laselle | Individual balls that can also be linked | 28 g, 38 g and 48 g | Allows several weight combinations; follow the linking and progression instructions |
| LELO Beads Noir | Two beads in a silicone harness | Two 37 g beads | Internal movement provides sensation during activity |
| LELO Luna Beads | Interchangeable bead set in Mini or Regular | 28 g and 36 g beads | Offers size and weight combinations in a harness |
| Pipedream Fantasy Train-her Set | Three cone-shaped trainers | 50 g, 80 g and 110 g | Simple graduated resistance set |
| Playful Diamonds Kegel Eggs | Six egg-shaped trainers | 50 g to 130 g | Wide progression range with textured grip |
| Satisfyer Strengthening Balls | Three single-ball trainers, 38 mm diameter | 61.9 g, 82.1 g and 97.9 g | Single-ball format may suit someone who prefers a shorter inserted body |
| Satisfyer V Balls | Three double-ball trainers, 34 mm diameter | 79.3 g, 114.1 g and 150.3 g | Longer double-ball format with higher total weights |
| Satisfyer Yoni Power 1 | Three egg-shaped trainers from 20–30 mm diameter | 22 g, 46 g and 74 g | The manufacturer’s progression begins with the largest trainer and moves towards smaller sizes |
| Svakom Nova | Progressive single and double-ball shapes with moving inner weights | 49 g, 75 g and 95 g | Progression changes weight, shape and size; check the product’s pregnancy, postpartum and infection warnings |
Research suggests weighted vaginal cones may improve urinary incontinence compared with no active treatment, but they have not been shown to be clearly better than well-taught pelvic floor muscle training. Weighted products are one possible exercise aid rather than an inherently superior method.
How do you choose a Kegel trainer?
1. Start with the problem you want to solve
Ask what you want the device to help you do:
- add resistance to a contraction you can already perform
- learn the timing of a structured routine
- see whether and how strongly you are contracting
- track progress and receive reminders
- increase awareness of the pelvic floor
If your main problem is pain, pressure, urinary urgency, constipation or difficulty relaxing, do not assume that strengthening is the answer.
2. Decide whether you need feedback or resistance
If you are confident that you can lift and relax the pelvic floor correctly, a simple weighted trainer may be enough. If you are unsure whether you are using the right muscles, measured feedback may be more useful than added weight.
A vibrating product can prompt or increase awareness, but vibration alone does not confirm correct technique.
3. Consider size, shape and comfort
An internal trainer should not hurt. Compare its:
- maximum diameter
- insertable length
- single or double-ball shape
- surface texture
- weight
- flexibility
- retrieval cord, handle or tail
A shorter single trainer may feel more manageable if you have limited internal space, while a longer or double-ball trainer may feel crowded. However, comfort depends on your individual anatomy and pelvic floor function, not cervix height alone.
If insertion feels dry, a small amount of water-based lubricant may help. Check the device instructions because silicone-based lubricants may not be compatible with silicone products.
4. Do not choose by weight alone
More weight is not automatically more effective. If a device is too difficult to control, encourages gripping or causes discomfort, the added resistance is unlikely to improve the quality of your exercise.
Progression also differs between brands. Some move from lighter to heavier weights. Others begin with a larger device that is easier to retain before progressing to a smaller one. Follow the sequence supplied with the specific set rather than assuming that the lightest or smallest option is always the starting point.
5. Think about how much technology you want
Before choosing an app-connected trainer, consider:
- whether your phone is compatible
- whether you are comfortable using Bluetooth and an account
- whether you value live data or would find it distracting
- charging and battery requirements
- whether the device remains useful if the app is unavailable
A more advanced device is only a better choice if its features make it easier for you to train correctly and consistently.
6. Check care requirements and product instructions
Check how the trainer must be washed, whether it is waterproof and whether any electronic section must remain dry. Use only compatible cleaners and lubricants. Explore cleaning washes and sprays if the manufacturer permits them.
Before use, read the instructions for recommended position, session length, progression, cleaning, storage and contraindications.
When might a Kegel trainer not be the right starting point?
Consider professional assessment before using an internal strengthening device if you experience:
- pelvic, vaginal, vulval, bladder, bowel or lower abdominal pain
- pain during or after penetration
- pain or difficulty inserting an internal product
- difficulty relaxing the pelvic floor
- difficulty starting urination or completely emptying the bladder
- constipation, straining or difficulty emptying the bowel
- vaginal heaviness, pressure or a bulge
- unexplained bleeding or unusual discharge
- a current vaginal, urinary or pelvic infection
- recent birth, miscarriage, abortion or pelvic surgery
- uncertainty about whether you are lifting the muscles or bearing down
Read our guides to overactive pelvic floor muscles, pelvic floor relaxation and vaginismus for more information.
Urinary incontinence and light bladder leakage
Supervised pelvic floor muscle training for at least three months is recommended as a first-line treatment for stress or mixed urinary incontinence. A trainer may support that programme, but it should not replace learning the correct technique or investigating other causes of urinary symptoms.
Clinical programmes may include at least eight contractions three times per day, but contraction length, rest time, progression and functional exercises should be suited to the individual. Do not automatically add this schedule to a device programme that has different instructions.
If leakage affects your daily life, read what to do about light bladder leakage and speak with your GP, continence nurse or pelvic health physiotherapist.
Pelvic organ prolapse
Supervised pelvic floor muscle training for at least four months may be recommended for some people with mild to moderate symptomatic pelvic organ prolapse.
A pelvic health physiotherapist can assess the prolapse and determine whether strengthening, coordination work, a pessary or another approach is appropriate. Do not assume that a heavier internal trainer is the best treatment for vaginal heaviness or a bulge.
Pregnancy and postpartum recovery
Product instructions vary. Some manufacturers permit use during an uncomplicated pregnancy, while others advise against pregnancy, menstruation or use for a set period after birth or surgery.
Check the exact instructions and ask your maternity care provider or pelvic health physiotherapist before using an internal trainer during pregnancy or postpartum recovery. Do not assume that the six-week check is automatic clearance for every person or product.
Using a trainer with an IUD
Some trainers may be used with an IUD, but check the individual product instructions and ask your healthcare professional if you are unsure. Be aware of the IUD threads during insertion and removal and stop if you experience new pain or think the threads have changed.
How often should you use a Kegel trainer?
There is no single schedule for every person or every device. Follow the instructions supplied with your trainer and any programme prescribed by your healthcare professional.
A good programme includes both contraction and complete relaxation. Stop the session if you develop pain, cramping, increased urinary urgency, difficulty emptying your bladder or bowel or a feeling that the muscles will not release.
Progress is usually measured over weeks or months rather than days. Longer sessions, more repetitions or greater resistance are not automatically more effective.
How to use an internal pelvic floor trainer safely
- Read the complete manufacturer instructions before first use.
- Check whether the product is appropriate during menstruation, pregnancy or postpartum recovery.
- Wash and dry your hands.
- Clean the trainer as directed and inspect it for damage.
- Use compatible water-based lubricant if needed.
- Insert the device gently and keep any retrieval cord or tail outside the body as instructed.
- Follow the recommended position, programme and session length.
- Relax fully between contractions.
- Remove the device slowly without force.
- Clean, dry and store it according to the product instructions.
An internal trainer should not cause sharp pain, burning, significant pressure, numbness or bleeding. Stop using it and seek appropriate advice if symptoms develop.
Frequently asked questions
Do Kegel trainers actually work?
Pelvic floor muscle training can help some conditions, including stress and mixed urinary incontinence. A trainer may provide resistance, structure or feedback, but results depend on having the right programme, using the correct muscles and practising consistently. The device itself does not guarantee improvement.
Are weighted Kegel balls or biofeedback trainers better?
Neither is universally better. Weighted trainers may suit someone who already understands the exercise and wants simple resistance. Biofeedback may suit someone who values visual guidance, tracking or reassurance. If you cannot identify the muscles or do not know whether strengthening is appropriate, professional assessment is more useful than either device.
How do you know whether your pelvic floor is weak or tight?
Symptoms can overlap, so it is difficult to determine muscle function from symptoms alone. Leakage may occur with weakness, poor timing or an overactive pelvic floor. Pain, urgency and constipation may also have several causes. A pelvic health physiotherapist can assess strength, relaxation, coordination and contributing factors.
Can Kegel exercises make symptoms worse?
Yes. Repeated strengthening may aggravate symptoms if the pelvic floor is already overactive, painful or unable to relax. Stop if exercises increase pain, urgency, constipation or difficulty emptying your bladder or bowel.
What weight should a beginner start with?
Follow the progression instructions for the exact product. Many sets begin with a lighter or larger trainer, but this is not universal. Size, shape and your ability to control the device matter as much as weight.
Should a Kegel trainer hurt?
No. You may notice the presence or resistance of the device, but insertion and exercise should not be painful. Stop if it causes pain, burning, bleeding or uncomfortable pressure.
Can you wear Kegel balls while walking or exercising?
Only if the manufacturer permits it. Some products are designed for short, focused sessions while others include instructions for use during movement. Do not assume that wearing a trainer for longer will produce better results and do not exceed the product’s recommended duration.
Is an app-connected trainer the same as biofeedback?
No. An app may control vibration without measuring pelvic floor activity. A biofeedback trainer uses sensors to detect aspects of your contraction and returns information about it.
The bottom line
The best Kegel trainer is not necessarily the heaviest, most expensive or most technologically advanced. It is the device that matches your goal, feels comfortable, provides the type of assistance you need and supports correct, consistent training.
Choose a weighted trainer if you already understand pelvic floor contractions and want straightforward resistance. Consider a sensor-guided device if you want a structured routine without an app, or an app-based biofeedback trainer if real-time visual guidance and tracking would help you.
If you have pain, difficulty relaxing, bladder or bowel emptying problems, significant prolapse symptoms or uncertainty about what your muscles need, arrange a professional assessment before beginning a strengthening programme.
