Our Story?
A class that blends calisthenics skills and weight-lifting strength, is there another in West London? Founded in 2026, the story of Sthenos is still being written and we want you to be a part of it.
Launched by Annur & Claudio two experienced personal trainers with the aim of providing the best hybrid experience for everyone by creating classes designed for progress.
They have helped people build strength in parks, in their homes, and in the gym, using the same principles that are applied in class. Put effort and execution first. Make every rep count. Don’t rush the process - because real strength is built over time.
Show up, do the work, and trust the process. The results will follow.

Claudio
My journey started in bodybuilding, built on iron, structure, and discipline. During lockdown, stripped of external weights, I was pushed into calisthenics — and fell in love with mastering my own body.
That experience shaped me into a hybrid athlete. I blend bodybuilding and calisthenics into one powerful method. Both are expressions of strength control: calisthenics through internal load, bodybuilding through external load. Together, they create balance, resilience, and real performance.
This class is where strength meets control, and aesthetics meets movement. Train smart. Move strong. Build a complete body.

My first pull-up was on my school gate. My first L-sit was in my bedroom. My first muscle-up was in the park. Strength started with curiosity, consistency, and using what I had.
I believe there are no boundaries to what you can achieve other than the limits you place on yourself. Will it always be easy? Hell no. But that’s exactly where growth happens.
