It’s important to keep fit while pregnant; an exercise routine can help prepare your body for giving birth as well as alleviate much of the discomfort of pregnancy. Some of the best pregnancy workouts include aerobic routines, walking, and swimming. All are safe, although pregnant women should obviously not overdo things. If you focus on only one of the above, swimming in the form of exercise most experts recommend. Swimming can help to alleviate nausea that typically accompanies pregnancy, as well as puffy ankles and sciatic pain. Swimming also improves circulation, boosts oxygen levels and strengthens the heart. All of this can help your baby as much as it benefits you. Many pregnant women also find it pleasant to be immersed in water as the feeling of weightlessness is a refreshing change from the feeling of carrying that extra weight.
