Kegel exercises strengthen the muscles of the pelvic floor by contracting and relaxing the perineal muscles. Regular practice of Kegel exercises can help prepare for childbirth, prevent urinary incontinence from coughing or laughing, and maintain good pelvic floor health throughout life. The exercises involve locating and contracting the perineal muscles for 5-10 seconds, relaxing for 10 seconds, and repeating 12-20 times in a session done 3-4 times per day.
