What is the best exercise for pregnant mum?

There are lots of exercises you can choose from. You just have to adjust the intensity if you're pursuing it. For obvious reasons, martial arts aren't advisable when pregnant, but I found swimming useful for relaxation. Prenatal yoga and dancing can be fun too! I did a bit of Zumba when I was pregnant. http://www.babycenter.com/0_the-best-kinds-of-exercise-for-pregnancy_7880.bc
