We are listed on the Companies House register, the Information Commissioner’s Office (ICO) register, and we are registered with HMRC.

We provide bespoke personal gymnastics sessions and group general gymnastics classes.

We were a REPs business partner (originally, REPs was the Register of Exercise Professionals in the UK), but we (and many Personal Trainers in the UK) were scammed by them in a deplorable subscription scam in September 2023. Be aware of this brand, now called REPs International!
