Tighten and Tense - Strengthen your pelvic floor-muscles for a better sex life.

Improve your kegel-muscles and get full control over your orgasms with these stylish balls in matt silky-smooth silicone. Inside each ball, there is a small ball that moves every time you move for extra stimulation.

Start by training for about 15 minutes at a time and keep in mind that just like with any workout, you will get exercise pain. Once you have trained for a while, you will also be able to wear them while you are shopping or at work.

As they are 100% waterproof, you can also run a workout while standing in the shower or lying in the bath. The small string at the bottom of the balls is for hanging outside, so you can easily pull them out when you are done.

Apply water-based lubricant to both the balls and the grinding opening for easier and more pleasant insertion.
