I get up for a while and walk around to see if the baby will settle down, I'll go back to bed and the baby starts again. I enjoy working out especially during my pregnancies because I feel healthier and know I will recover quicker from delivery and be in good shape sooner after delivery. If you feel good you should continue your exercise. It benefits you in a huge way not only physically but most important - emotionally. Nature is preparing your stomach muscles to separate to make room for the expanding uterus.
Stomach exercises now can actually slow down the recovery of abdominal tone after birth.
This is all it says. Unfortunately this book was written in 1995. I am at 16 weeks and wonder if I should continue to do crunches. I am the mother of 2 children and one due in Aug. I never excersized with my other children while pregnant, but with this pregnancy I am extremely out of shape.
