What are some exercises I can do in preparation for labor?

Several. Just staying physically fit is enough for labor but a few of my favorites include swimming, yoga, and pilates.
Daily walk. A daily walk is my favorite exercise for pregnant patients. Getting outside and walking for 20-30 min a day helps keep your muscles loose, burns calories, increases your metabolism and helps you sleep better a night. Stretching and prenatal yoga can also help prepare your muscles for labor.
