Intimina Laselle Kegel Exerciser 38g Weighted Ball are designed to make your pelvic floor exercises easier and more effective. The 38g mid-weight exerciser offers medium resistance for women experienced in weight-free pelvic floor exercising. By giving you an object to contract around, this exerciser helps ensure that you are using the correct Kegel technique (lifting upwards and squeezing). The additional weight of the exerciser adds more resistance to your routine - just like a weight at the gym. Laselle gives you a more effective Kegel workout that, when done regularly, builds both vaginal strength and tone.
