Kegel exercises are movements that work your pelvic floor, a muscular area that supports your pelvic organs, including your bladder, uterus and vagina. Kegel exercises contract those muscles. You can start doing Kegel exercises whenever you want, including before and during your pregnancy. Doing them regularly is the best way to get stronger down there. Strengthening these muscles can lower your risk of bladder leakage after you give birth and even improve your sex life.
