One of the reasons she bounced back so quickly is that she stayed active while pregnant. Gisele told a Brazilian newspaper, "I did kung fu up until two weeks before Benjamin was born, and yoga three days a week." She was also "mindful" of what she ate, which meant not overindulging or eating for two.
It's important for women, whether they're models or not, to remain active during pregnancy. As with Gisele, it can make it easier to drop the baby weight once your little one arrives, but there are also numerous benefits during the pregnancy. Many women swear that it helps them maintain a healthy weight while pregnant. It can also alleviate uncomfortable symptoms including back pain, leg cramps, fatigue, and sleep issues, and can lift your mood when hormones get the best of you. Not to mention, it'll keep your body strong and prepare you for childbirth.
It's recommended to do 30 minutes of moderate exercise a day, including running (if you were doing it pre-pregnancy), walking, swimming, yoga, and strength training. Be sure to check in with your doctor about appropriate forms of exercise for you. Above all else, listen to your body, don't overdo it, and if certain types of exercise cause pain, don't do them. And once that little bundle of joy is born, talk with your doctor about when it's appropriate for you to get back to a workout routine.
