Reformer Pilates focuses on controlled movement, targeting muscles you might not even know you had.
Although the craze is high right now, Reformer was invented by Joseph Pilates during World War I, when he adapted hospital beds with springs to help rehabilitate patients.
But despite Reformer Pilates becoming increasingly popular, with celebrities such as Ed Sheeran taking up the exercise, the industry is not formally regulated.
Nathan Benjamin-Smith, owner of Reformer Pilates Bicester in Oxfordshire, said: “From my perspective, it’s less about a shortage of instructors, and more about the rapid growth of the industry outpacing the availability of highly experienced, well-trained professionals.
“As demand has increased, there’s also been a rise in shorter training courses, which can vary significantly in depth and quality.”
Hosking says “there is always evidence evolving and changing” and that “you never stop training as any exercise professional”.
“There’s so many training providers now, you seem to be able to get a training in a very short amount of time,” she said.
“I was definitely trained in an era where it was quite a remedial approach to teaching Pilates.
“I feel that with the increased amount of reformer studios it’s more of maybe an athletic approach which is probably coming over from across the waters… there’s a lot of changes in the industry and I definitely feel that there’s space for some more control and just to keep people safe.”
