The Double Kegel Training Ball will help you get your pelvic floor muscles in shape in no time! The Kegel ball is made from a gorgeous silicone material and has a handy loophole for easy removal. It has an insertable length of 3 inches and a girth of 4.75 inches at its widest point. To use this Kegel training ball, simply coat the balls with a high quality water based lubricant and then gently insert them into the vagina until only the handle is left outside the body. Then as you move about you will feel the balls start to slide out, clench your pelvic floor muscles so that the balls go back up into the vagina. This action helps to train and strengthen these muscles to gain a tighter vagina or to help control your bladder movements. With this Kegel training ball, you can train yourself to a happier sex life!
