Well, I climb with Multiple Sclerosis and the choice is both crazy and sane. It's crazy cause it wipes me out and increases my symptoms but it is sane because it helps my mental health and makes me feel powerful. *shrugs* You have to weigh the benefits with the problems.

I wouldn't recommend starting climbing while pregnant but I know a number of women who have climbed or are currently climbing while pregnant. However, they were all climbers prior to getting pregnant.

If you do climb, I'd recommend getting someone to show you how to tape your fingers to protect them and add Vitamin C to your diet as that helps the skin/blood vessels heal. For me, most of my injuries have been finger stuff (skin peeling off and tendon problems) and bruises on my knees. For whatever reason, the way I move on the wall bruises my knees but that is really just my problem instead of an issue with climbing. Strength training actually increases bone density so climbing may help you there.
