Kegel exercises - Exercises to strengthen the muscles of the pelvic floor, which are particularly stressed in pregnancy and childbirth. Kegels can increase strength and control of muscles used in labor and delivery, and help stop urine leaks. To do a Kegel, squeeze the muscles that you use to stop the flow of urine. Hold for 10 seconds, then release. Do this 10-20 times in a row at least three times a day.
