Pregnancy keeper: Kegels
Why: They're not just for childbirth. These vaginal-tightening exercises help strengthen the pelvic floor, can prevent bladder problems, and add to sexual satisfaction.
Good habit helper: This may be the only exercise you can do while watching TV, sitting in the car, or talking on the phone. As a reminder, to locate the muscles, try stopping and starting the flow of urine -- that's the motion of the Kegel. (Don't do the exercises while you're urinating, however.) The National Institutes of Health recommend doing 10 kegels three times a day, and Austin does them for five seconds a few times a day. Start them after childbirth (check with your doctor first), and keep doing them until you're a grandma!
