I go to the Bodywise Studio on Gwydir Street (off mill road, town side of the railway bridge) for my regular (non-pregnant) pilates. www.bodywisestudio.co.uk/index.htm. They didn't do pregnancy classes when I was pregnant but they have a new lady there now who does so take a look. It's lovely there. I did the Shelford pregnancy pilates and that was great too, but would probably look at Gwydir Street if ever needed to again.
