The pubococcygeus muscle (or PC) is part of a network of muscles that supports your internal organs, like the uterus and bladder. It is located deep in your pelvic region. Having this muscle strong helps with your vaginal health and even avoids small pee "leaks" when you laugh or jump a lot. Exercising this area, lightly and consciously, is a great way to connect with your body's internal strength. It is your foundation of well-being!
