Kirstin Ferrie, the former personal pilates teacher of Duchess of York Sarah Ferguson, has expanded her pilates studio in Ilkley, West Yorkshire.

Ferrie launched the Pure Pilates studio in May 2010 and in the first month had a two-year waiting list of clients. Due to the popularity of her classes, she is now nearly doubling the size of the site.

While the original studio space will benefit from new equipment, there will also be a new private studio are for one-to-one work. It will feature equipment from US-based manufacturer Balanced Body and the new CoreAlign and a Reformer Trapeze Combo.

Ferrie says: "Since I started the studio three and a half years ago, my dream was always to help more people and ensure that those injured or with a disability could also benefit from the method.

"Currently classes are either individual or for small numbers, but now I can plan to have up to 10 in the new matwork studio. I'm also considering the possibility of introducing other disciplines with suitably qualified instructors."
