The KegelMaster is a progressive resistance vaginal exerciser designed to perfect the pelvic floor exercise called the kegel. Regular use of the KegelMaster significantly increases vaginal muscular strength and blood circulation to the vaginal region. This innovative device helps women to strengthen their pubococcygeal muscles, also known as PC muscles, which form a hammock or sling underneath all the pelvic organs and are responsible for 1) controlling the flow of urine, 2) supporting the bladder, uterus and rectum, and 3) contracting during sexual orgasm. The KegelMaster relies on the basic principles of progressive resistance exercise which is essential in reconditioning weakened muscles. Progressive resistance is the type of exercise most commonly taught in medical and rehabilitation facilities, health clubs and sport gyms. The goal of using the KegelMaster is to strengthen vaginal muscles which typically weaken from childbirth, lack of use, age, hormone fluctuations, neurological disorders and other causes.
