Frequently asked questions
The kGoal Boost is a non-insertable, sit-on-top device that allows you to engage in pelvic floor training externally while fully clothed.
If you are looking for more precise feedback, the kGoal Classic is an insertable women’s trainer that offers a higher level of measurement accuracy compared to the Boost, making it ideal for functional exercise while moving.
Finally, the kGoal IntimFlex is also an insertable trainer. While it shares a similar physical design with the Classic, the IntimFlex is specifically tailored for intimate fitness training—particularly alongside the LiBDO courses developed by Irina Pivtsaikina—and includes an extended six-month trial of the kGoal+ premium app features.
kGoal+ is a premium app subscription available for $5/mo that unlocks advanced features beyond the standard free guided workouts.
It includes:
- Access to Background Workouts (Allow you to measure and record pelvic floor activity while using other apps, watching videos, or participating in live classes)
- More in-depth metrics and data analysis
All devices include an initial free trial of these features—1 month for Classic and Boost, and 6 months for the IntimFlex model—to help you determine if the advanced insights fit your routine.
Doing pelvic floor exercises can improve blood flow to the pelvic region and enhance the strength of muscle contractions during climax.
For men, improved pelvic muscle control is linked to better stamina and erection performance, while for women, this often leads to increased sensation and ease of orgasm. The IntimFlex women’s model is specifically tailored to support these intimate wellness goals.
Yes, kGoal products are generally safe to use with an IUD. That said, we advise against using any kegel training devices immediately following the insertion of an IUD—we recommend confirming with your doctor whether it’s safe to proceed.
Before using any kGoal trainer postpartum, you must wait until all incisions or tears have fully healed and you have received official clearance from your doctor (typically at the 6-week postpartum checkup).
For insertable devices like the IntimFlex, it is generally recommended to wait at least six weeks after delivery.
Alternatively, once your healthcare provider approves light pelvic floor exercises, the non-insertable kGoal Boost is often a fantastic, gentle starting point for your recovery journey and can often begin earlier than 6 weeks postpartum.
Absolutely; in fact, this is the best way to use a kGoal trainer. Many users find that kGoal is the perfect companion to professional physical therapy. You can even input custom workout parameters provided by your therapist into the kGoal app, allowing you to follow their professional guidance with the benefit of the device’s precise biofeedback and tracking.
Simply wipe down the device after each using with a damp cloth, mild soap, and warm water, or use antibacterial sanitizing wipes.
Never submerge the device fully in water and allow it to air-dry completely before storing.
Yes, kGoal understands the personal nature of pelvic health and ensures that all orders are shipped in plain, discreet packaging. There is no mention of the product’s name, specific function or the brand name on the outside of the shipping box, so your privacy is maintained from the warehouse to your doorstep.
