Continue lifting weights?
“If you’ve been lifting weights, you can probably continue with your program (ask your doctor!) but you may have to lift lighter weights since you could strain your joints. When lifting, make sure that you don’t hold your breath, ease up on the weights as you progress through your pregnancy and consider using machines during your last trimester. Also, try to avoid any jumping or jarring movements. Your main goal during pregnancy is to maintain your health, not make dramatic strength gains or muscle mass, so take it easy!” This info comes from the following page which I think you might find interesting; http://exercise.about.com/health/exercise/library/weekly/aa031901a.htm?
