Did you know that working out your Kegel muscles can prevent urinary incontinence and make your sex life amazing? Kegel exercises work out your pelvic floor muscles, which control urine flow as well as sexual functioning. They are in both men and women and are known as the pubococcygeal muscles (PC muscles). The name Kegel comes from Dr. Arnold Kegel who studied these muscle fibers which are located between the anus and the pubic bone.
