I am fascinated and impressed by these pregnant ladies working out with a big pregnant belly. Judging by some of the comments to these videos, some people seem to think that exercising during pregnancy can be harmful, when in fact there are few exercises and activities that are contraindicated in a healthy pregnancy.

Did you know that pregnant women have even participated in the Olympic Games? Swedish figure skater Magda Julin was three months pregnant when she took home the gold in the 1920 Summer Olympics. German Diana Sartor was nine weeks pregnant when competing in the skeleton in the 2006 Winter Olympics. Last year Canadian curler Kristie Moore was five and a half months pregnant when she participated in the 2010 Winter Olympics.

Pretty cool, huh?
