Hi,
I've been going to CORE for about a month now for equipment pilates classes and really enjoy it. They're just off of St. John's Hill, on Sangora Road. The website is
www.coresw.co.uk. What's great is that the classes are small - only 3 people to one teacher and it's personalised to your body. I think it's worth checking it out.
Hope you find somewhere you like!
Liz
