Boost: Sit-On-Top
Kegel Trainer for Men

- or -

Boost™ is a revolutionary, interactive training system for your pelvic floor muscles. It consists of a sit-on-top device that measures pelvic floor muscle activation (you can leave your clothes on) and a smartphone app. It is designed to help with both strengthening (Kegel) exercise and relaxation (Down Training). Boost provides a unique combination of workout guidance, exercise tracking, biofeedback, and games to help you get more out of your pelvic floor exercise and build consistent routines.

Boost: Sit-On-Top Kegel Trainer

Pelvic floor exercise is important for men

The pelvic floor is a network of muscles at the base of the abdomen that plays a crucial role in many aspects of healthy living. Whether you’re trying to improve bladder control, boost your performance in the bedroom, or just set yourself up for healthy aging, Kegel exercise can be a key part of the equation.


But sticking with a Kegel routine can be hard (and boring!). That's where Boost comes in:

1. Sit Down on Boost
(with your clothes on)

2. Open the App

3. Your Kegels control games and guided workouts in the app

Boost puts you in the driver's seat. Your Kegels control games in the app:

90 % of our users say that games and guided workouts help them exercise more frequently.

Kegels vs. Down Training

Like other muscles, pelvic floor muscles need to be strong to do their job. Kegels are great for strengthening the pelvic floor.

But these muscles can become too tense, which can cause pelvic pain and can prevent them from functioning well. That's why Down Training, or practicing pelvic floor muscle relaxation, is so critical. It can complement Kegels or even replace them if you struggle with pelvic pain or other symptoms of an overactive pelvic floor.

Boost is the first smart pelvic floor trainer to also offer Down Training, which perfectly complements the wide range of Kegel workouts and games in the app.


Easy to use.
Just sit down on Boost (with your clothes on), open the app, and begin exercising. The soft Air Pillow conforms to your body and senses your Kegels.
Makes Kegels fun.
Exercising is more engaging if you turn it into a game. Boost puts you in the driver's seat, with your Kegels controlling games in the app in real time.
Guided Workouts.
Boost takes the guess-work out of Kegels, by guiding you through adaptive games and workouts focused on both strengthening and relaxing (Down Training) the pelvic floor.
Tracks Performance.
Exercise is much more fulfilling when you can measure your progress.
Pelvic floor muscles are hidden. Biofeedback promotes good technique and results.

Getting Started with Boost

Frequently Asked Questions

We've compiled the most common questions we get about Boost, along with our answers below (click on each question to view the answer). If you have any other questions, please browse our complete Boost Quick-Start Guide, and don't hesitate to contact us at We will respond within one business day (and often sooner!).

The Boost device

Press and hold the Power button on Boost for at least 1 second. When Boost turns on, the Status Light should light up in white.

Press and hold the Power button on Boost for at least 2 seconds (the circular blue button between the Soft Air Pillow and the Status Light). When Boost turns off, the Status Light should turn off as well.

It depends on whether you have the vibration biofeedback turned on, but the worst case should be 2 hours of usage per charge and usually it will be more.

Use the micro-USB charging cable that came with Boost. You can plug the other end of the cable into any USB port (e.g. computer, charge adapter for your phone or other devices, etc). When charging, the Status Light on Boost will be pulsing in green. When it is done charging, the light will change from pulsing to continuously on, still in green.

Boost should charge in 90 minutes or less. When charging, the Status Light on Boost will be pulsing green. When it is done charging, the light will change from pulsing to continuously on, still in green.

This is common when Boost travels, especially by plane or to a place with different elevation (like the mountains). It’s no big deal, though -- just press the Travel Vent on the bottom side of Boost to open the valve for a second (making sure you’re not squeezing the Soft Air Pillow). That will let Boost equalize the pressure in the Soft Air Pillow and reinflate.

It’s probably not calibrated to your current body position; you can manually recalibrate at any time by briefly pressing the Power button on Boost, or while you’re in a workout by pressing the Calibrate button in the app. Always make sure that your pelvic floor muscles are fully relaxed (and try to have good posture) when you calibrate.

The other possible explanation is that you may be shifting your weight by leaning around slightly -- this will change your weight distribution on Boost and thus change the reading, so it’s important to have good posture and a quiet / still body position when you’re doing workouts. If you do shift your weight or adjust your body position during a workout, just tap the Calibrate button.

There are two ways. You can press the Calibrate button in the top right of any workout screen in the app (during a workout).

Or, anytime Boost is turned on, you can recalibrate by briefly pressing the Power button on Boost (if you hold it down too long, though, you’ll turn Boost off).

Whenever you recalibrate, it will cause Boost to re-zero the measurement baseline at the instant that you calibrated, so try to have good posture and fully relax your pelvic floor muscles when you do it.

Use the toggle switch in the Settings tab of the app. When the toggle is “on”, Boost will provide vibration biofeedback during workouts. When the toggle is “off”, Boost will not provide any vibration biofeedback.

No, Boost is not waterproof. But it shouldn’t ever need to be -- if you need to clean it, you can just wipe it down with a damp washcloth.

It should stay pretty clean, but if you need to clean it you can wipe it down with a damp washcloth.

The Boost app

The Boost app is compatible with iPhones/iPads and Android devices (Android version 10 and newer) that have Bluetooth Low Energy (BLE) compatibility. Please ask us ( if you're unsure about compatibility with your device.

The app will automatically try to connect to Boost whenever it is launched, so it’s a good idea to turn Boost on before you open the app. Or, you can always manually connect or disconnect using the “Connect” or “Disconnect” button in the Settings tab of the app.

The workout scores are all on a scale of 0-10 where 10 is the best. But, they are designed as a relative tool and not absolute. In other words, there is no specific number or range that is universally “good” for all users. If your scores are increasing (on average; it’s normal for there to be day-to-day fluctuations) then you’re on the right track.

Scores are provided for the overall workout and for specific aspects of muscle function; namely Strength, Endurance, and Control (which includes the ability to relax your pelvic floor muscles).

Each workout is designed so that it forces you to work on multiple different aspects of your pelvic floor muscle function, such as strength, endurance, muscle motor control, muscle relaxation, and quick-twitch muscle response. They are also intended to be more fun than just sitting around and doing Kegels on your own. Or, if you want to really zero in on certain aspects of your muscle function, the Custom Workouts tool is a great way to do that.


No. In general, Boost should be able to accurately measure your pelvic floor muscle activation even through your pants (please note that it is important to make sure that you are calibrating Boost at the beginning of each workout). The one exception in terms of clothes is if you are wearing really stiff pants; this may interfere with Boost’s measurements and require a change of clothes to use it.

Boost works well with nearly all types of clothing. The one exception we have found is if you are wearing extremely stiff pants (really stiff denim is an example). In this case, you may need to change clothes to something more relaxed to use Boost.

Sit on it like it’s a bike seat, with your perineum on top of the Soft Air Pillow. Most people find that having the button pointing backwards works best but either orientation (button in the front or the back) can work.

There are a few potential reasons. The most common is that you may be shifting your weight (for example, leaning slightly forward / backward / sideways) -- it’s important to maintain both good posture and a quiet / still body position during each workout and always press the “Calibrate” button if you do shift your weight. It’s also possible that you could be activating other muscles in the pelvic region, such as your glutes, abs or inner thigh muscles. If you’re having trouble with this and not able to figure it out, please contact us at for more thorough and personalized troubleshooting.

No, Kegels / pelvic floor strengthening is not always the right move. In particular, those with pelvic floor muscles that are hypertonic / overactive / high tone (in other words, too tense), should not do Kegel exercise. This is often characterized by various types of pelvic pain.

However, Boost also has Down Training workouts, which are designed to help people with overly tense pelvic floors to practice relaxing their muscles.

If you’re unsure whether Kegels or Down Training (or both) are right for you, talking to a pelvic floor physical therapist is a great place to start.

There is a good bit of flexibility here. Exercising every day, for 5-15 minutes per day, is probably the optimal regimen, but we know that doesn’t fit into everyone’s schedule. Our experience has been that doing at least 5 minutes of pelvic floor exercise per day, 3 days per week, generally results in measurable improvements in pelvic floor muscle function (i.e. Boost workout score averages) within 6-8 weeks. But exercising more frequently will generally lead to faster and/or larger improvements. Listen to your body and be sure not to over-exercise.

It depends on your starting point, and your workout regimen (how much and how often you are doing workouts). But if you’re working out at least 3 days per week, for at least 5 minutes per day, our experience is that you will usually see measurable improvements in pelvic floor muscle function (i.e. Boost workout score averages) within 6-8 weeks.

Imagine that you’re peeing and you need to stop mid-stream. The muscles you just flexed are your pelvic floor muscles, and you just did a pelvic floor muscle, or Kegel, contraction. It’s also helpful to visualize a lifting and squeezing sensation.

The first thing to do is to select a workout in the app, while holding Boost in your hand and squeezing -- make sure that the app / workout is responding correctly when you squeeze. If that is the case, it means your Boost is working and there are two common other explanations. It could be your technique -- see the FAQs on How to do a Kegel. If you’re confident that your technique is good, and that you’re activating your pelvic floor muscles (and not your glutes, abs, or inner thighs), the other explanation is that it could be a calibration issue. Try to recalibrate manually at the beginning of the workout by pressing the “Calibrate” button in the app and see if that helps. If it’s still not working please contact us at for more thorough and personalized troubleshooting.
