Congrats! I just found out 2 days ago to :) I to workout 4 times a week but doing zumba I plan on continuing to do so just to stay in shape....
ps...CONGRATS!!! what an exciting christmas gift!!
from what I was told, if you did it before pregnancy, you should be safe to do it after, you just don't want to start up an exercise routine AFTER finding out because it would be too stressful on your body. so I would suggest to just do your cardio, at a lower rate then you normally would, and when you see your dr to confirm your pregnancy, talk to him about what he suggests. I've seen pregnant women do weight lifting but they have to be very careful so I would say hold off until you talk to a dr and maybe use a personal trainer.
