Same. I didn't exercise at all with my first pregnancy either and despite what people say, I was still able to push her out (no epi) and lost all the baby weight 9 months PP.
Pushing was a b*tch though, and really took a toll to the point that I vowed I would exercise during my next pregnancy. I was so out of breath that they were giving me oxygen, and I didn't know I was even using half of the muscles that were sore for a week. I couldn't lift my arms past my shoulders for days.
Still, so far this pregnancy I haven't done diddly.
