It all began in the 1940’s when a doctor called Kegel invented a series of exercises designed to give women stronger pelvic muscles. The Kegelmaster PC muscle trainer teaches your body the art of these exercises – and the best part is the progressive training, so you can increase intensity at your own pace. This resistance exerciser increases blood flow and has 15 strength settings – so you can gently notch up the increments when you feel ready. Three inches are inserted into the vagina, where the knob opens up and closes using resistance to train the muscles. Stronger pelvic muscles even promise easier childbirth. You’ll also feel tighter, taking your orgasm to an A+ in the carnal classroom. This gadget gears you up for pleasure and play and the health benefits keep your vagina fit and feeling feminine.
