Our Story

We are sisters Irina and Liliya who came to the UK many years ago and set up separate businesses.


Irina is a former gymnast and worked with professional athletes. Irina has an immense passion for fitness.  Being a former gymnast has influenced her training style. She developed her own Irina K Fitness Method and successfully trained with professional athletes,  also  high profile and corporate clients. She has been working for the major fitness clubs in central London including in the Knightsbridge area.


Liliya worked providing therapy, coaching and training to individuals and businesses, to improve working relationships and countering stresses in the workplace. Liliya also worked  in the NHS and with  The Priory North London. She trains strategic ways of dealing with anxiety, depression and traumatic stress, using CBT and DBT approaches.


Having worked successfuly with many thousands of clients, all along we recognised that something was missing. We realised that our clients needed to combine our two approaches. They encouraged us to blend our  methods (vast experiences and expertise).

That was why we set up TheraFit London, to provide a range of approaches that can be taken under one roof so that a range of professionals could contribute where needed. We came up with what we call the Korallo Method.

Our 5 main principles are:

Clarity, Discipline, Commitment,  Consistency and Pleasure.

  Our clients found that the Korallo method was uniquely helpful, it targets individual challenges.
