Most people who know me know I'm pretty squeamish about pregnancy, so here's a topic I never expected to discuss on this blog: should pregnant women continue to bike commute? My first reaction was no, they should be hidden away out of the site of the non-pregnant public. I have to admit that's not fair though. This thread on the 'Bike Commute Tips Blog' by author Paul Dorn says bicycle commuting can be a particularly healthy activity for expectant mothers, even up to the week before giving birth.
He emphasizes that pregnancy is definetely a time when women need to use caution in their physical exertion, but says bicycling is among the best exercise during pregnancy because of it's smooth motion, it doesn't require lifting or jumping, and you can choose your level of exertion.
So read the article and let me know if you, your spouse, or a friend commuted by bike while pregnant and how that worked out.- SL
