My dr told me to continue my workout regime but to go easy & try to keep my heart rate down. I did Zumba classes twice a week throughout, my last being when I was 39+6. I continued w weights as well, just a much lesser weight than usual. Listen to your body, take breaks when you need to & stay well hydrated. I fully believe it helped so much w labor & recovery. My first I was a couch potato, had to be induced, long labor, pushed for 2 hrs & recovery SUCKED!! With my second (when I worked out) went into labor on my own on my due date, it was much faster, pushed only 1.5 times & recovery was a breeze!

It will help with delivery and after. So, yes it will. Just don't over do it.
