Pro boxer Darren Sealy opens Flow State Fit Club in London

A new boutique firtness group training concept, called Flow State Fit Club, has opened in Clapham Common, London, positioning itself as a structured, coaching-led alternative within the capital city’s competitive boutique fitness sector.

Co-founded by performance coach and professional heavyweight boxer, Darren Sealy and commercial finance specialist, Sujit Pancratius, the concept combines elite athletic methodology with operational discipline and a focus on long-term member development.

Flow State Fit Club is built around controlled growth rather than rapid expansion and Sealy brings over 16 years of experience in commercial gym environments and professional boxing. He has trained and sparred alongside world-class athletes including Anthony Joshua and Oleksandr Usyk.
