The concept behind kegel balls is that, while inserted vaginally, the weight of the balls forced the pelvic floor to contract in order to retain them inside of the body. The larger and lighter the ball is, the easier it is to hold it in, and the smaller and heavier the ball is, the more difficult it is. Nova balls are great for assistance in strengthening the PC muscles through kegel exercises, and gives you something to resist against -- just like with any weight training! Inside of every Nova exercise balls, there's a built-in moving metal ball. As you move, the metal ball collides with the inner surface, creating subtle vibration and making the exercise even more enjoyable. This set allows you to start at a comfortable level, and work your way up as you gain strength. Strong PC muscles allow the vagina to both expand and contract more comfortably, as well as a more acute awareness and control of the same muscles that autonomically contract during orgasm.
