Ballet??

Yesterday, I enjoyed a fun ballet workshop for the over 50's. To be honest I can't say any of us looked like elegant dancers, but I realise that, despite never doing ballet since i was about 7 years old, this is a fantastic way to build muscle tone, stretch and exercise - and have fun at the same time. However, I can't find any classes in the area for 'mature' ladies. There are a couple of dance studios which have adult classes but most of the adults are around 22! There seems to be lots of specialist classes in London, so i thought there must be something in the Manchester/Trafford area? Can anyone help?
