Here is your very private training app. Elvie, the exercise tracker for your pelvic floor.

There are no buttons on the exerciser, as you’d hope given it’s designed for internal use. Indeed, the entire pebble-shaped device is encased in medical grade silicone — giving it a smooth, seamless unibody for hygiene and comfort. Since Elvie is designed to sense force applied almost anywhere on its body the whole device is also effectively one big button. (The user activates the link between app and Elvie by squeezing the device with their pelvic floor muscles once they’ve inserted it into their vagina — at which point the app will offer to guide them through a workout.)

I’ve been at it for six weeks, using the elvie approximately 4 times a week, and I’m ecstatic to announce that I no longer have to cross my legs and brace myself every time I sneeze. I can laugh as hard as I want without needing to change my pants. I can practice jumping with my son without soaking my uniform (read: yoga pants). And I’m back to being my free, dancing self—no adult diapers needed.

I have only just started using Elvie- it is really easy and I have already felt results. It is great that women are finally getting a chance to understand their bodies.

Wow this really works! My core is stronger, my pelvic floor is stronger than ever and still improving. I can actually feel the difference in just three weeks. Two of my friends have now converted and one has said the pelvic floor muscle exercises have helped ease her back pain. A must-buy, I'm totally in love with my Elvie, it's my new best friend.
