A state-of-the-art boxing gym in the heart of London. By professional boxers, for everyone.


Founded by two boxing aficionados, Karim Baladi & Daley Perales want to bring their shared passion out of the professional sphere and make it accessible to everyone.

They envisioned opening their own boxing gym to fill a gap in London from the moment they met. Trenches Boxing falls between fitness boxing classes, often lacking proper boxing technique and pure professional boxing gyms catered to professional boxers.

Karim met Daley when he was looking for a boxing coach in 2016. He quickly got captivated by Daley’s unique training method for professional boxers: The Daley Effect.

Five years later, in 2023, professional boxing coach Rhys Verlander came on board to create the perfect team. And just like that, the time has come to share their passion with the world.

Whether a professional boxer, a seasoned amateur, or a newcomer, boxing is for everybody. It is a way of life, a way of being in the world rather than just a sport.

We want to take the intimidation out of the professional boxing scene and invite everyone to experience the empowerment of being in the ring.
