With my first...I took prenatal water aerobics and loved it. A pool full of pregnant ladies. I walked with audio books outside and did a bit of exercise weekly in the apartment complex gym. The walking and gym were very low intensity.

Maybe I walked a bit with the second...that is kind of a blur...just trying to be pregnant and the mom of a four year old and keep up with his needs. I would have done the water aerobics but we weren't living in the same town and I couldn't find it in our new location.
