The coach
Stefan Kirjonen
Performance Coach / HYROX Athlete
Stefan Kirjonen is the founder of SCIFIT and coaches with a focus on strength, conditioning and movement quality — built for both performance and a body that lasts in everyday life. He is an Eleiko-licensed Personal Trainer and works with a method that combines clear progression, high technical quality and smartly dosed intensity.
Stefan's training philosophy is rooted in combat sports, where discipline, body control and efficient movement patterns are the foundation. That background shapes his coaching: clear basics, a strong focus on technique and a practical approach where every session has a purpose.
Beyond coaching, Stefan is an active HYROX athlete competing regularly, with qualification for the HYROX World Championships in 2025 and 2026. That gives an insider perspective on what it actually takes: pacing, capacity building, station strategy and how to train hard without breaking down.
Private one-to-one training is available at Adlon, with the option of structured online coaching if you want to keep a clear plan after your stay.

The team
Georgy Dias-Johnson, MSc
Performance Specialist
Georgy Dias-Johnson brings more than 25 years in strength, conditioning and applied sports science, with a Master's in Training and Performance from GIH, Sweden's leading university for sport and health sciences.
He has worked in elite environments — Team GB rowers, Bosön, the Åstrand Laboratory and GIH's LTIV Laboratory — where physiology, performance testing and evidence-based practice shaped his method.
Before performance science, he spent 20 years as a professional dancer across Europe and Asia in ballet, jazz, contemporary and street, alongside a lifelong martial arts background: a rare understanding of movement and biomechanics.
Through GMETHOD.CO he works exclusively with executives, entrepreneurs and discerning individuals who value health, strength and longevity. Every session is tailored to improve body composition, movement quality, energy and resilience.
Private one-to-one training and performance consultations are available exclusively for hotel guests, with bespoke online coaching available after your stay.
