The health industry is loud.

Full of quick fixes, empty promises, and people who see you as a number.

CAIRO exists to be different.

We raise the standard of health, training, and lifestyle- through coaching that's research-led, holistic, and built around you as a person. Not a transaction.

We don't chase trends. We don't make claims we can't back up. We hold ourselves to a higher standard ,and we hold the industry to one too.

What CAIRO offers

Our coaches

Callum founded CAIRO after a career as a professional Muay Thai fighter - and after the kind of setback that forces you to rebuild from the ground up.

He knows what it takes to perform at the highest level. He also knows what it takes to start over.

That combination is rare. It's why his coaching goes beyond technique.

Whether you've never trained a day in your life or you're preparing to compete, Callum meets you where you are - and takes you further than you expected to go.

Where we train

  • CAIRO is a training, wellness, and lifestyle brand built around a single principle: raising the standard. Through coaching, education, and apparel, CAIRO exists to protect people from the noise and toxicity of the modern health industry - delivering trusted, research-led, holistic support. We are not a gym chain, a clothing brand, or a coaching company in isolation. We are a movement around disciplined living.

  • Contact us directly via our website or social channels. All new client relationships begin with a conversation - not a self-serve checkout. This allows us to understand your goals, match you to the right coach, and ensure the coaching relationship is right before a single session takes place.

  • Yes. For every 10 sessions or workshop booked, CAIRO donates one session to partner charities supporting children with special needs, individuals with disabilities, those in palliative care, care home residents, and vulnerable communities. Giving back is not an afterthought - it is built into how we operate.

  • No. CAIRO exists for anyone who wants to be better - regardless of starting point, background, or goal. From someone entering a training environment for the first time to elite-level competitors, the quality, care, and attention is the same. Dignity is not performance-based.

  • CAIRO actively supports people with disabilities, those rebuilding after injury or setbacks, elderly individuals, and those with specific health needs. Elite-level care is not reserved for elite athletes. If we are not the right fit for your specific situation, we will be honest about that and help direct you to the right professional - your wellbeing matters more than retaining you as a client.

We're based across Hertfordshire, with partner gyms in Kings Langley and Hoddesdon and sessions expanding into St Albans soon.

But the gym isn't the only option.

If you'd rather train at home, CAIRO comes to you. No commute. No unfamiliar environment. Just focused, one-to-one coaching delivered wherever you're most comfortable - at the same level you'd receive anywhere else.

The location changes. The standard doesn't.
