I've heard amazing things about Bebe PT in Santa Monica. They do prenatal yoga, pilates, physical therapy.. everything. You can also continue to go after you have the baby and you can even bring them to class with you. Good luck!
YogaCo on 3rd St Prom. They have great classes on Mondays/Wednesdays and then a mommy and me class on Sundays. I've been going here for a few months and I love it!
Re: Rec's for prenatal yoga in Santa Monica or near?
Santa Monica Yoga on Ocean Park is fantastic https://www.santamonicayoga.com/
They have lots of pre-natal and mummy and me classes throughout the week
