I found an awesome pre and postnatal Pilates program in Corte Madera. I have taken classes at other studios but all the instructors at this place are incredibly knowledgeable and have taken many of my friends through one or more of their pregnancies. What I like best about this place is that it is kid friendly. They even let my 7 year old work out next to me. Of course I get a better workout when I don't have the kids but it's nice to know they are welcome if I have to bring them. The name of the studio is Fit First and Jessan's classes seriously melted off my baby fat!
