Exercising while pregnant is good for the baby

Medicine and Biosciences monitored 26 pregnant women who were divided into groups of exercisers and non-exercisers, and used a non-invasive device to measure the magnetic fields of maternal and fetal heart rates to see if fetuses whose mothers exercised had increased breathing movements (fetal breathing is practice for babies getting ready to breathe on their own after birth). The results found that the fetal breathing movement and the nervous system were more mature in babies exposed to exercise. The women who were grouped as “exercisers” did moderate aerobic exercise like vigorous walking, stationary biking and running 30 minutes three times a week.
