Exercise any one?

Anyone here go to the gym or exercises? If so, do you avoided all abs workout or you do it too? I take the body conditioning class and Body pump class but there are parts for abs and not sure if I should avoid it.

Not seeing my doctor for another 3wks. I am currently 20 wks.

Thanks for helping.

Thank you mamas for answering my questions.

Most instructors can tell, my belly looks like I am 9 months instead of 20 wks. Lol, it is my 3rd child so it doesn’t hide well. I only done prenatal yoga with my first 2.
