Exercising
Should a woman continue to exercise once she has become pregnant? Aerobic exercise appears to have no harmful effects on the majority of pregnant women. One difference found is that exercising mothers seem to have shorter periods of labor. No significant differences have been found between the birth weight, body length, head circumference or condition at birth of babies born to exercising mothers and those born of mothers who did not exercise. It may be advisable for women who have preeclampsia, a condition characterized by elevated blood pressure, water retention, and albumin in the urine to not exercise while pregnant.

Don't skip meals!
While pregnant, especially during the last three months of pregnancy, women risk "accelerated starvation" and low blood sugar if they skip a meal. Always eat breakfast!

Walking while pregnant
This can benefit both mother and child, according to a British study. Women who walked while pregnant vs. those who did not had shorter labors and less need for pain-relieving medication.

Weight gain in pregnancy
Thin or underweight women should gain the most weight for a healthy pregnancy while overweight women should keep weight gain to a minimum. Weight gain greater than 32 pounds where harmful regardless of the weight of the mother before becoming pregnant.

The added weight of being pregnant comes from an average of a 7.5 pound baby, 1.5 pounds of placenta, 2.5 pounds of amniotic fluid where the baby floats, 2.5 pounds in her uterus, and 1 pound in each breast. There is also an increase of about 4 more pounds in blood volume for a total of about 20 pounds.

I have had a lot of women in my water aerobics exercise that stayed in it all the way through their entire pregnancy. Many of the women have come and told me how much better they feel after exercising. Any time you can take gravity out of the equation it helps with the back pain that usually occurs during pregnancy. Exercise also helps to prevent gestational diabetes.

my wife is thin
what kind of exercise that you recommend for her while pregnant?

Does your wife have access to a gym that offers water aerobics? I would recommend that! Water aerobics is a low impact workout that can keep her muscles moving while reducing pain during pregnancy. Water aerobics has been shown to help during labor. According to a study published in the journal Reproductive Health, a course of water aerobics classes done by sedentary and low risk pregnant women has been shown to reduce the amount of pain-killing medication women request during labor.

For many pregnant women, exercise seems to provide an easier delivery, a quicker recovery time and a faster loss of the gained weight after the birth.

Thin is not the main indicator... "How healthy are you?" is the real question. Does she regularly perform aerobic activity? If she does is it vigorous, moderate or light? If not, water aerobics is a great place to start. Y'all should consult with her doctor first, but a gentle yoga class and light weight bearing exercise routine would probably be beneficial in recovery and weight loss after the child is born.

thanks for this post. she's not having any exercise yet but i will recommend her the water aerobics
