We always put all this stress on how exercising while pregnant is really great for the mom, and makes it easier for her to get back to her pre-baby weight. However new research sort of brings us back down to earth on the most important benefit of exercising while pregnant: it's generally good for the baby too. Here are details from Dr. Linda E. May of Kansas City University of Medicine and Biosciences:
"When the mom exercises during pregnancy, the unborn baby gets the same type of training effect that you would see in an adult — so you see the lower heart rate and also improved heart rate variability, which is evidence of improvements in the nervous system of the heart. Maternal exercise may be the earliest intervention to improve the heart of children and possibly the best," May concluded.
So if you're expecting like Jessica Alba or plan to be in the future, don't just exercise for yourself, do it for your baby.
