Any ideas on pregnancy exercises?

"Exercise during the second trimester of pregnancy can be very important in keeping up your energy level and helping you sleep well at night. It can also help prepare your body for labor and prevent too much weight gain" - Mayo Clinic, 2010
For now, I have been doing some brisk walking in the mornings and in late afternoons. No specific pregnancy exercises as of yet. It's advisable because it lessens the pain and numbness on several parts of my body and they say it eases out childbirth.
