I read this article and it said that the only problem to lifting heavy weights late in the pregnancy was because of the womans center of balance being thrown off and she could hurt herself. But lifting weights over twenty pounds did not effect the baby's growth or cause defects.

From today.msnbc.msn.com: "Late in pregnancy a woman's ability to safely lift a load decreases, mostly because her center of gravity and balance have changed and additionally because the hormones of pregnancy have caused her connective tissue, ligaments and tendons to soften. So if she lifts a heavy load she can injure herself, but will probably do no harm to the pregnancy or the baby. There are no studies that show that lifting more than 25 pounds has an effect on birth weight or prematurity. The current recommendation is that the maximum load a pregnant woman should lift in late pregnancy should be reduced by 20 to 25 percent from that which she was able to lift in her pre-pregnancy state."
