With the help of SATISFYER Yoni Power 1 Kegel exercises, you can strengthen your pelvic floor and enjoy more intense orgasms. Compared to other Kegel training balls, the Yoni Power 2 focuses not only on the weight, but more importantly on the size of the ball! As a Yoni Power 1 beginner, you start with the largest and heaviest ball (3 cm diameter, 74 g) and work your way through medium (2.5 cm diameter, 46 g) to the smallest and lightest ball (2 cm diameter, 22 gram). The more you train your pelvic floor, the tighter your muscles will be, so you can finally hold the ball with minimal pi. You only need to use these balls for 15 minutes a day to achieve results that not only you but also your partner will notice during vaginal intercourse. The ribbed structure of the ball also stimulates you during training. WARNING: Keep the product away from children.
