Good news for baby

I've read and read and read about exercise during pregnancy.  Even after making the decision to continue to run and bike while pregnant you still question the decision with each little ache and pain.  I read something in the New York Times today that makes me feel even better about the decision.  So, not only is it good for mommy and make for easier delivery and labor, but it could be beneficial to our babies heart - win, win!  :-)
