The Gym Group has done it again. The high-value, low-cost fitness powerhouse — and the UK’s largest National HYROX Training Club — has just pulled off something few gym chains could dream of: rolling out a world-class HYROX training programme across more than 120 locations without breaking stride.
Working hand-in-hand with fitness tech specialist ONE FIIT, The Gym Group launched the HYROX365 Performance Hub, a slick digital ecosystem designed to keep members sweating, smiling, and coming back for more.
The ambition was bold yet brilliantly simple — deliver consistent, high-quality group training nationwide, while making life easier (and cheaper) for staff. And it’s working.
The HYROX365 Performance Hub now offers:
- Eight workouts per week designed by HYROX’s top programming experts
- Coach-facing training notes to standardise class quality
- Equipment filtering tools to adapt to each gym’s layout
- And a growing community of members chasing personal bests under one unified system
Jenni Tardiff, National Group Exercise Manager at The Gym Group, explained the motivation behind the rollout: “We knew there was demand from our members for HYROX-style workouts and ONE FIIT made it easy for us to scale while ensuring our trainers had the tools and confidence to deliver standout classes.”
Over at The Gym Group Chichester, General Manager Chris Hall has seen the impact firsthand: “My HYROX classes are more varied, engaging, and accessible. The filtering feature makes my life easier as a coach. Members keep coming back – and they’re performing better too.”
That last line says it all. Members are thriving — and so are the trainers.
For ONE FIIT founder and CEO Ian McCaig, the collaboration wasn’t just about another tech integration — it was about redefining what scalable excellence looks like in the fitness world. “We built the HYROX365 Performance Hub to solve a real challenge: how do you scale premium group training without compromising on quality or overwhelming your team? The Gym Group’s success shows what’s possible when you give trainers the right tools and programming. You get consistent experiences, engaged members and classes that practically run themselves.”
It’s that combination of tech precision and human touch that sets The Gym Group apart — and it’s paying dividends. With over 250 locations, 900,000 members, and 65 million visits a year, the brand continues to redefine what a modern, affordable gym can be.
They were the UK’s first carbon-neutral gym chain, pioneers of 24/7 flexible membership, and now, the undisputed leaders in scalable HYROX performance.
Not bad for a company that built its empire on the promise of accessibility.
