If you're looking for (or even open to trying) prenatal yoga, i highly recommend 8Limbs. I just had a baby a month ago and I attended prenatal yoga up until a week or two before my due date. The studios (both on pike and 35th ) are among the best in town and Annefife, the teacher of my class on pike, is an absolutely amazing instructor.
I'm not a 'yoga person' per se so i don't usually go for the 'sharing' aspect of yoga, but i found this class very satisfying physically and also supportive emotionally. physically, it is gentle enough to be appropriate for even someone 40 weeks pregnant, but challenging enough to feel like a workout. plus late in my pregnancy it showed me i could move in ways i didn't think possible at 7, 8, or 9 months. emotionally, i found the 10 minutes or so each week the class spent sharing tips on pregnancy maladies or birth stories surprisingly helpful. i learned a lot about the wide range birth experiences - something that helped me get a sense for what to expect.
so even if you're not into yoga, try it!
