I took one at the Herndon Community Center that I really enjoyed, but they had to cancel it because the instructor was ill. I'm not sure if they've hired someone new, but it's worth checking out their website if you're interested.
Sun & Moon Yoga--they have 2 locations, one of which is in Fairfax on Little River Turnpike.
I currently go here, to the Fairfax location, and love it. They have a Sunday night class for 90 minutes, and another on Thursday, I think. It so relaxing and I've learned some good stretches for my aches and pains of pregnancy.
I've been taking it at Beloved Yoga and love it. They have Reston and Great Falls locations, though I've only been to the Reston one. Classes are Sat mornings or Thurs nights in Reston and Sunday mornings in GF.
