The weight of the vaginal balls rests on the muscles, causing them to contract spontaneously. This provides an internal workout and creates biofeedback that shows you where your pelvic floor muscles are located and how you can strengthen them. The vibrations generated by the balls inside enhance this effect. Performing your Kegel exercises with the balls helps you discover how to tighten your pelvic floor muscles. By making an effort to keep the balls in place, you improve your endurance and strength. Simple movements, getting up from a chair, climbing stairs, or coughing - with the vaginal balls, you learn when to engage your pelvic floor muscles. The exercises promote blood circulation in the pelvic floor area, thereby improving the vascularization of these muscles. A strong pelvic floor can significantly enhance your sexual arousal, sexual response, the intensity of your sensations during intercourse, and your ability to reach orgasm.
