we are
At Sisu, we do things differently.
We don’t believe in random workouts or aimless classes. Every group session is part of a carefully designed programme that builds week on week, so you don’t just show up and hope for the best. You get stronger, fitter, and more confident with purpose.
Our group training isn’t just a class, it’s a community. You’ll be guided by expert coaches who ensure you’re progressing safely and effectively, with structure, support, and accountability every step of the way.
We’re passionate about creating real change, both physically and mentally. At Sisu, you’ll find a welcoming space where you’re empowered to take control of your fitness journey and become the strongest version of yourself, both mentally and physically.
Our philosophy?
Strength, resilience, and success are earned, not given.
Based in our private, well-equipped facility in Medway, Kent, we deliver results through intelligent programming, expert coaching, and a powerful sense of community.
