If you don't find one locally, try this prenatal yoga video - https://yogaone.com/cart/products.php?prod=9 My mom bought it for me and it's really nice to work at your own pace. Plus it's approved by OBGYN's to be safe. Just don't wait too long to start a prenatal work out like I did - I triggered braxton hicks because I didn't start something until I was in my late 2nd trimester.
The only place I know of is in Montgomery at Blue Cocoon. That is were I have been going. Not sure of any in your area but check out the ones that they just posted or call around.
