Natural Contours has created the perfect weight-resistance trainer for the pelvic floor muscle: it's sleek, effective, and ergonomically shaped for comfort. No longer content to lose their sexual prowess, women are seeking a long and active sexual life. As was discovered by Dr. Arnold Kegel through his work in the 1940's, a toned PC (short for pubococcygeus) muscle is essential for pleasurable feelings and can lead to stronger orgasms. Childbirth and natural aging weaken the PC muscle, situated at the pelvic floor, causing incontinence and a loss of pleasurable feelings, even orgasm. Strengthening this muscle through exercise can help prevent urinary incontinence as well as maintain the ability to enjoy an active and fulfilling sex-life. The most effective way to strengthen a muscle is by weight-resistance training. Using the NERGIE Kegel exerciser will provide a safe and pleasurable way to maintain and tone your PC muscle before and after childbirth as well as after menopause.
