There’s one major problem with following all those celebrities suit and taking up Reformer Pilates: it’s an expensive business, with classes coming at up to £30 a pop, which sort of makes sense when you factor in the cost of the machine itself, and the fact that an instructor can only properly keep an eye on a certain number of attendees so classes tend to contain fewer people than, say, a yoga class might — but where does it leave anyone who can’t afford to join but would like to benefit from the stress-reducing, muscle-building, core strength-focussed joys of Reformer Pilates?
