UK Reformer Pilates Boom Raises Safety Concerns Among

Published: 04 April 2026. The English Chronicle Desk. The English Chronicle Online

The rapid rise of reformer pilates in the UK has created what experts describe as a “wild west” of studios, where inconsistent regulation, inexperienced instructors, and poorly maintained equipment have contributed to an increasing number of injuries among fitness enthusiasts.

Reformer pilates, a full-body, low-impact workout performed on a machine using springs, straps, and a sliding carriage, has become widely popular for its ability to strengthen and stretch muscles in ways that traditional mat-based pilates cannot. Classes in London often cost between £20 and £37 per drop-in session. However, industry insiders warn that some studios are capitalising on the trend without adhering to recognised standards, leaving participants at risk.

The unregulated nature of pilates means anyone in the UK can claim to be an instructor without formal training. Traditional pilates instructors argue that this has diluted the practice, while newer studios defend their methods as making pilates more accessible. Videos on social media platforms, particularly TikTok, frequently show pilates accidents, highlighting the potential dangers.

Last year, 30-year-old Essex instructor Kirsty Morgan spent seven hours in A&E after a 20kg metal tower attached to a reformer machine fell on her head during a demonstration. Morgan required multiple stitches and a tetanus shot, and was told the incident could have been fatal. Similarly, acclaimed violinist Maya Meron suffered a career-ending injury in 2019 when a proprietary Coreformer machine collapsed at a London studio, breaking her elbow and causing abdominal injuries.

Michael King, a founding member of the Society for the Pilates Method (SPM), warned that large classes with 20 to 25 machines and a single instructor present “a deeply concerning” safety risk. “While some instructors maintain high standards, there are also operators where training is minimal, which can lead to unsafe practice,” he said.

Industry professionals, including solicitor Philippa Wheeler from Leigh Day, emphasised that equipment safety and proper instructor training are critical. Unsafe reformer machines and poor guidance on their use could cause life-changing injuries, she said.

The Pilates Teacher Association and other professional bodies are calling for improved “quality assurance” in the sector. Sarah-Jane Walls, a Glasgow-based pilates teacher and podiatrist, cited trauma injuries, neck strain, and poor core engagement as common problems arising from unsafe practice.

Reformer pilates has transformed the UK fitness landscape, but experts insist that its growth must be balanced with regulation, instructor certification, and rigorous equipment standards. Without these measures, the popularity of pilates could continue to expose participants to unnecessary risks.
