Getting Started

Using the Travel Vent

Make sure Boost is not over- or under-inflated. To do this, press the Travel Vent with your finger, while making sure not to squeeze the Soft Air Pillow, then release the Travel Vent.

If you travel (especially by plane or to a different elevation), it is normal to have to equalize Boost’s inflation level with the Travel Vent before using it again.

Press and hold the Button on Boost to turn it on or off. When Boost turns on, the Status Light should light up in white and when it turns off, the Status Light will turn off.

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.

When Boost successfully connects to the app, the light will turn blue.

If Boost is not connecting to the app, double check that Boost is turned on (white light is illuminated) and Bluetooth is enabled on your phone. Then refer to the following troubleshooting tips, which will vary depending on whether you are an iOS or Android user.

  1. Go to the iOS Settings, and scroll down to select the "Boost" app from the list of apps installed on your phone/tablet (listed in alphabetical order).
  2. Make sure that "Bluetooth" is enabled (the slider is turned "on") in the "ALLOW BOOST TO ACCESS" menu, as shown in this image:
  3. After ensuring that the Bluetooth slider is enabled, return to the Boost app and try connecting again by pressing the "connect" button in the Settings tab.

Android 10+

  1. Go to your Android phone/tablet settings
  2. Go to the Privacy settings
  3. Choose Permission Manager
  4. Choose Location
  5. Scroll down and click “Boost” in the list. It will likely either be in the “Allowed Only While In Use” or the “Denied” section.
  6. Set the permissions to “Allow Only While Using The App”

Android 9 or lower:

  1. Please go into the Settings on your phone (the Gear icon) and use the Search field to look for “Location”.
  2. Under location, there should be a section called “Improve accuracy”. If you click on that, there should be a toggle labelled “Bluetooth scanning”. Please make sure that toggle is enabled.
  3. Also in the phone Settings (not the Boost app settings), search for “Boost” using the search bar and then under “App Settings”, make sure that the location toggle under Permissions is enabled.

Interact with Boost in your hand at first, so you get the idea of how it works.

Once you’ve connected to the app, hold Boost in your hand and select the Moving Target workout. From the Workout Instructions screen, you’ll be able to see visual biofeedback in the background when you squeeze the Soft Air Pillow with your hand. The harder you squeeze, the higher the bar should go. If you have Vibration Biofeedback enabled in the app Settings, the motor will also buzz when you squeeze Boost during a Workout or on the Workout Instruction screen.

Boost needs to be on a flat, firm surface (no squishy couch cushions). You can leave your clothes on (unless your pants are super stiff). Sit down as if Boost were a bike seat, with your perineum on top of the Soft Air Pillow (the perineum is the part of your body just behind your scrotum). Most people find that it works best to have the button pointed backwards but either way (button to the front or the back) works.



Sit up straight and keep your body posture quiet (avoid shifting your weight). When you are first practicing with Boost, one option is to practice by sitting on the floor (on top of Boost) next to a wall so that you can keep your back flat against the wall. This will help you make sure your posture stays good and get some practice getting your technique right.

The Boost app offers a number of guided workouts and games, which can be accessed in the Workouts tab. They are all designed to give you a balanced workout that helps target different aspects of muscle function, including Strength, Endurance, Motor Control, and Relaxation. When you first click on a workout, the app will take you to the instructions screen for that workout, with a button to start the workout when you’re ready.

Boost will auto-calibrate the instant you select the workout, so it’s best if your pelvic floor muscles are fully relaxed when you do.

Boost measures the pressure in the Soft Air Pillow, which changes when you do a Kegel. It needs to be calibrated at the beginning of each workout so that it can ignore the pressure exerted by your body weight sitting on it.

Boost will auto-calibrate at the beginning of each workout, so as long as you are sitting on Boost with your pelvic floor muscles relaxed (that part is critical) when you select a workout then you should be all good. But if your muscles aren’t relaxed, or you shift your weight during a workout, you can always recalibrate manually at any time. Again, just make sure your pelvic floor muscles are fully relaxed when you do. In general, the best way to Calibrate is using the Calibrate button in the top right of the screen (this button is present only when you are in a workout). You can briefly press the Power button on Boost itself to calibrate if you prefer.

Imagine you’re trying to stop peeing in mid-stream (without using your hands), while also avoiding passing gas. That squeezing and lifting of your pelvic floor is a Kegel. Avoid flexing your abs, thighs or butt muscles. If you put a finger on the skin of your perineum (the part of your body just behind your scrotum), you should feel your skin move when you do a Kegel. Lastly, mind your posture -- if you are leaning around or shifting your weight it can interfere with Boost’s measurements (and undermine your workout gains).

Once you’ve calibrated Boost and are trying your first Kegels, you may need to experiment a little with the placement of Boost relative to your body (front to back) but you should be able to find a position where you can see the biofeedback response on the app when you Kegel (after calibrating, of course).

The App

There are 4 areas of the app: Dashboard, Workouts, Settings, and Help. You can navigate between them using the buttons on the Navigation bar at the bottom of the screen

The Dashboard is where you can find your exercise history data, including active streak (how many days in a row you have worked out), a customizable graph showing your workout scores from all past workouts, and your lifetime squeeze count. You choose whether each Workout Score metric (Overall score, Strength, Control and Endurance) is shown or hidden on the graph by clicking on the label.

The Workouts tab is where you choose which workout/game you want to do. Boost comes with a list of 5-minute options you can choose from (see below), or you can create your own Custom Workout.

When you select a workout, Boost will instantly auto-calibrate, so it’s a good idea to already be positioned in place with your pelvic floor muscles fully relaxed when you choose a workout. If you shift your weight or need to calibrate again at any time (in general, you’ll know you need to recalibrate if you’re seeing biofeedback from Boost even when you’re not doing a Kegel), that’s no problem -- just press the Calibrate button in the top right corner of the app screen (or briefly press the Button on Boost, which will also trigger a calibration). Remember to make sure your pelvic floor muscles are fully relaxed whenever you calibrate, though.

After you choose a workout, you will first see an Instructions screen explaining how that game/workout works (like the below), and then you can press a button to begin the workout whenever you’re ready. Each workout will guide you through actions that target different aspects of pelvic floor muscle function, including strength, endurance, motor control, fast-twitch response, and relaxation.

When you finish (or exit) a workout, the app will show you a Workout Summary screen that provides scores for the overall workout and each sub-category of muscle function (Strength, Endurance, and Control, which encompasses motor control and muscle relaxation/down-training).

The scores are on a 0-10 scale, where 10 is the best. But be aware that, due to variance in different users’ bodies, the numbers are a relative tool and not an absolute one -- in other words, there is no universal threshold for what numbers are “good” or “bad”. If your scores are improving over time (on average; it’s normal for there to be day-to-day fluctuations), then you’re on the right track. You can read more details about what the scores mean here.

You can see and control your account credentials in the Settings (e.g. see your username or sign out). You can also manually connect or disconnect to Boost. There is a toggle switch to enable or disable the vibrational biofeedback in the Boost device. You can also set Workout Reminders by clicking on the Workout Reminders button. Lastly you can see which version of the app is installed, change the language, or access the Terms of Service and Privacy Policy.

The Help section contains this very Instruction Manual, as well as a Frequently Asked Questions (FAQ) section that has some great troubleshooting information. Lastly, you can contact us at boost-help@kgoal.com if you have any questions and we’ll get back to you within 1 business day.

Boost (the device)

Boost has a non-removable, rechargeable battery. Use the micro-USB charging cable that came with Boost to recharge it. 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.

The battery life depends on whether you have the vibration / tactile biofeedback enabled, but should be at least 2 hours of usage per charge and usually more. It should take about 90 minutes for Boost to fully recharge.

The figure below describes what different colors for the Status Light mean. Note that when charging the light will be pulsing green and it will change to continuously green when charging is complete.

Boost is not waterproof, so don’t submerge it or hold it under running water. If you need to clean it, wipe it down with a damp washcloth.

When Boost travels, especially by plane or to a place with different elevation (like the mountains), it is common for it to become over- or under-inflated. 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.

When you do a Kegel, or pelvic floor muscle contraction, a bunch of muscles, ligaments, etc in your pelvic floor move, which causes there to be motion in the surface of your perineum. When you’re sitting on Boost (with your clothes on), this changes the pressure that’s being applied to the soft Air Pillow by your body, and that is what Boost measures.

Usage Recommendations

No. In particular, those with pelvic floor muscles that are hypertonic, or too tense, should not be doing Kegel exercise, since this can exacerbate pelvic pain or other problems that hypertonic pelvic floor muscles can cause. More generally, the ultimate authorities on your body / pelvic floor muscles are you and your doctor or physical therapist -- checking with them about any questions or problems is always the right idea.

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.
