G.I.
This location might be too far for you but I took a wonderful prenatal yoga class through Beloved Yoga in Reston. It's $130 for 10 classes and our teacher, Maryam, was voted one of the best yoga teachers in 2008 Washingtonian. Their website is www.belovedyoga.com. Good luck in your search! They offer a Thurs eve class from 5:30-6:45pm and a Sat AM class at 9:15a-10:45am. This was my 1st prenatal yoga class ever and I loved it. The only reason I stopped was due to my recent work & home schedule that has gotten soo crazy :/
