kGoal Kegel Exerciser Comparison: kGoal Boost vs. kGoal Classic

With pelvic-powered video games, real-time feedback and results tracking, kGoal trainers help you stay consistent and motivated with a Kegel routine that's actually fun.

Both the kGoal Classic and kGoal Boost are devices for strengthening your pelvic floor muscles, which can help improve incontinence, core weakness, sexual satisfaction and more.

Because they were designed by the same company, there are a number similarities between the two products. Using the same app and games, you can use your Kegels to control objects in a video game, like a pinball machine or moving bricks.

But there are also major differences: The kGoal Classic is inserted vaginally, while the kGoal Boost detects your Kegels as you sit on top of the device.

We'll help you decide which kGoal Kegel exerciser is right for you in this comparison from Vagercise, an authorized retailer of both products and creator of the online course for pelvic floor exercise and education.

Differences Between kGoal Boost and kGoal Classic

We'll provide an in-depth comparison in this post, but here's a summary of the key differences and similarities between the kGoal Boost and the kGoal Classic Kegel trainers.

The biggest difference is in how the devices measure pelvic floor muscle activation: intravaginally for kGoal Classic and externally for kGoal Boost. 

The kGoal Classic can be used in various positions—whether you're laying down, standing or doing movements like squats—while the kGoal Boost requires that you sit on top of it.

Both Kegel trainers share these qualities:

• They offer guided and gamified workouts to help make pelvic floor exercise more engaging and to make sure you’re getting a well-rounded workout each time 
• In addition to strengthening workouts with Kegels, they offer Down Training programs to help relax the pelvic floor and prevent tension
• They provide biofeedback, both visually via the app and via tactile notifications from the device itself
• They measure and track your pelvic floor exercise performance over time so you can see if you’re improving

What is kGoal Classic?

The kGoal Classic is the original gamified Kegel trainer, designed with the help of pelvic floor physical therapists more than a decade ago.

The device has a Control Arm that remains outside the body and an insertable Squeeze Pillow with 360-degree sensors that measures muscle activation directly through the movement of the pelvic floor muscles. The design offers these advantages:

Wide variety of uses

Because it is insertable, kGoal Classic can be used in a variety of scenarios and allows you to exercise your pelvic floor during real-life, functional positions.

This can include standing, walking, going up and down stairs or even simultaneously doing Kegels with exercises like squats, lunges, or core work. 

Accurate measurements

kGoal Classic provides accurate reporting on your pelvic floor fitness because it is taking measurements directly from inside the vaginal vault. 

360-degree sensors enable the device to take accurate measurements across a wide range of orientations and placements.

Adjustable sizing

The Squeeze Pillow is inflatable and deflatable so the size can be adjusted to optimize for comfort. 

Feedback

The kGoal Classic has two biofeedback motors to help you understand your Kegels: one in the internal Squeeze Pillow and one in the external Control Arm.

The motors vibrate to provide tactile feedback when you contract your pelvic floor, helping you better connect with muscles you can't see. (The vibration can also be disabled.)

Other Kegel trainers only provide visual feedback through an app, which kGoal devices also offer through games.

What is kGoal Boost?

The kGoal Boost takes a different approach to measuring pelvic floor muscle activation—from the outside, not inside.

The Boost looks kind of like a bicycle seat that detects your Kegels through your clothing.

To use kGoal Boost, just place the device on a firm, flat seat and sit down on top, with your perineum in contact with the blue Air Pillow.  

When the pelvic floor muscles are contracted or relaxed, it causes motion in the surface of the perineum. Boost measures this motion to determine how strongly you are activating your pelvic floor. 

As the only externally-used Kegel trainer, the kGoal Boost offers these unique advantages:

Ease of use

Because you can leave your clothes on and just sit down on top of it, Boost is incredibly easy to use.

The kGoal Classic and other insertable pelvic floor trainers can be more time-consuming, typically requiring privacy, time and clean-up after usage. That can make them more of a challenge to fit into a busy schedule.

Better comfort without insertion

Because it is used externally, the kGoal Boost is a better fit for women who experience pelvic floor tension, compared with intravaginal devices.

Symptoms like bladder leaks can be caused by either pelvic floor weakness or tension, and many women have a combination of both.

That's why both kGoal devices offer Down Training workouts, with breathing and meditation exercises for pelvic floor relaxation instead of strengthening.

But kGoal Boost is the better option for women who may have tension and discomfort with an insertable device.

How to Use kGoal Classic and kGoal Boost

Both kGoal Classic and kGoal Boost offer the same 5-minute workouts that help build strength, endurance and control in the pelvic floor muscles.

kGoal recommends daily exercise for the fastest results, but working on your pelvic floor muscles at least 3 days per week typically leads to noticeable results within around 12 weeks. 

The big difference is that you sit on kGoal Boost, compared with inserting kGoal Classic vaginally. While this makes Boost easier and quicker to use, it also means that kGoal Classic can be used as part of a more functional workout routine. 

Instead of only accommodating use while you’re sitting down, kGoal Classic allows you to combine pelvic floor exercise with actions like standing, walking, going up and down stairs, or even doing other types of exercises like squats or lunges.

kGoal App for Boost and Classic

Both products use the same app, which offers the same games and workouts. However, some aspects of usage depend on the product.

Games and Workouts

kGoal Classic and kGoal Boost offer the same Kegel games for strengthening workouts:

1. Moving Target
2. Spaceship
3. Pinball
4. Shape Shift
5. Bricks

Both devices also offer the ability to create Custom Workouts, allowing you to add your own sets and reps using the Moving Target template.

In addition, both kGoal Classic and kGoal Boost offer the same Down Training and Combined Workouts:

1. Diaphragmatic Breathing
2. Mindful Meditation
3. Elevator Ride, a workout that incorporates both relaxation and strengthening phases

However, because insertion can cause pain in women who have pelvic floor tension, Boost is the better choice if you expect Down Training to be a core element of your workout regimen or if you know that vaginal insertion can be painful for you.

Dashboard and Performance Tracking

Both products have the same functionality in tracking your workouts over time.

kGoal devices give you an overall score for every workout, help you build daily exercise streaks, keep track of your Lifetime Squeeze Count and provide an Exercise History graph with scores for Strength, Endurance, and Control.

Settings and Configurations

For both products, you can adjust the sensitivity level, access help and welcome materials, set workout reminders and manage the Bluetooth connection. 

Biofeedback

kGoal Classic has two biofeedback motors that vibrate when you perform a Kegel, whereas kGoal Boost only has one. 

For Boost, you can only turn the single motor off or on, but kGoal Classic, you can individually enable or disable each of the two motors based on your preferences.

With either device, the vibrational biofeedback is proportionate to how strongly you activate your pelvic floor muscles. The harder the squeeze, the stronger the vibration.

kGoal Price and Specifications

Because kGoal Classic is an intravaginal product and kGoal Boost is not, comparing dimensions is not really an apples-to-apples exercise. But it’s still worth a quick look.

Price

The kGoal Boost and Classic are the same price of $199.

Dimensions

• kGoal Boost: 8" x 4" x 1" (not insertable)
• kGoal Classic: 3.6" x 2.5" x 1.5" insertable diameter

Weight

• kGoal Boost: 5 oz
• kGoal Classic: 2.8 oz

Battery

Both products have a USB rechargeable battery that lasts at least two hours and typically much longer.

Warranty

Both kGoal devices are protected by two-year manufacturer's warranty in the event of defects or problems.

Compatibility

Both devices use the same app that can be used with Apple and Android devices. 

Apple devices need to be running iOS 13 or higher (which was released in 2019) and Android devices need to be running Android 8 or higher (which was released in 2017).

Which is Better: kGoal Boost or kGoal Classic?

Both kGoal Classic and kGoal Boost are great tools for pelvic floor fitness, providing physical and visual biofeedback, exercise measurement and tracking over time, and guided and gamified workouts.

If you prioritize combining pelvic floor fitness with functional movements and exercise, and if you want the most accurate measurements possible, kGoal Classic might be the right choice. 

If you want a device that's easier or quicker to use, or if you know that reducing tension with Down Training will be an important part of your pelvic floor exercise routine, kGoal Boost is more likely to be the best bet.
