I used to be a manic gym bunny up until i got pregnant - I do bugger all now! I really should do some right?
Theoretically - assuming you are healthy and there is no medical reason not to - yes... If you did very regular exercise before beign pregnant, then that is what your body is used to and - in all honesty - maintaining exercise will keep your stronger for a more active birth and help you bounce back quicker (energy, weight and fitness) after the birth...
I still aim for 4 gym sessions a week (normally get in 4 - only 3 if I am very busy/tired) and one pre-natal yoga session (used to do regular pilates/yoga, but not really advised any more and the pilates was really knackering me out). I DID start reducing the intensity of my gym sessions as soon as I BFP'd. Two days before I BFP'd I went for a 4 mile run and felt like ABSOLUTE DEATH afterwards for a couple of days (I had a BFN that morning, but how I felt after the run kind of tipped me off
). So that was a sign to watch the intensity of what I did - haven't been running/jogging since. Plus - until about 12 weeks pregnant - I felt more fatigued... so slowing things down was a way to cope. At 14/15 weeks one of the gym instructors redid my gym routine to be "pregnancy friendly". It is fine at the moment.
You would have to be careful starting again after doing nothing, but speak to one of your gym instructors and see what they suggest. The other alternatice is swimming - GREAT exercise during pregnnacy. You aren't looking for the same things, from exercise, in pregnancy as you were before: you are just trying to maintain some fitness/strength/health and help you bounce back a little easier after birth.
Pre-natal classes (with a good instructor) are a must... I wouldn't call it "exercise", but it is definitely "birth preparation" and it is great to meet other pregnant women and get experience/advice. Love it
Oh, and if you are inclined, get a swiss ball at home (being a gym bunny you might already have one). You want one so that, when you sit on it, your hips are a little higher than your knees. Great for justing sitting on (for your posture) and for bouncing on, rocking on, doing little circles on, figures of 8 etc... supposed to really promote a healthy back for you and a good birthing position for baby
