Jack Knight - Founder & Head Coach
My coaching began with a childhood dominated by sport and a lifelong fascination for how the body moves. After qualifying as a Personal Trainer in 2012, I completed a BSc in Sport Science (Strength & Conditioning) in Cambridge, specialising in biomechanics, anatomy, and performance.
Over the past decade, I’ve worked with executives, professionals, and athletes across London and Sydney, including leading one of Europe’s largest corporate gyms at HSBC HQ in Canary Wharf and later at Lockeroom Gym in Sydney.
I founded JKPT to help people take back control of their health — moving better, performing better, and sustaining results that last.
I am incredibly happy to now offer our structured Personal Training in Bank as well as Canary Wharf.

George Keach - Coach
My fitness career began at 17 when I joined the Parachute Regiment, serving across Kenya and the UK. After leaving the military in 2017, I qualified as a coach through the Army resettlement scheme and began my career in fitness.
Since then, I’ve coached across London — from Virgin Active to Head Coach at Train Canary Wharf — leading small-group and 1-to-1 programmes while supporting clients to rebuild strength and resilience.
At JKPT, I combine that same quietly competitive drive with a focus on helping people test their limits safely, build confidence, and enjoy the process of becoming stronger.

Alex Mardapittas - Coach
My journey into coaching began with a love of sport and competition — from football to Brazilian Jiu-Jitsu. After serving in the Special Forces of Cyprus, I earned my BSc in Sport & Exercise Science at Swansea University, where I developed a deep understanding of human movement and performance.
My career took me to Canary Wharf, where I joined Fitness Mastery’s graduate programme, then progressed to Studio Manager at Sweat Clubs. Those experiences taught me how to lead and develop people within a high-performance environment.
Now at JKPT, I’m proud to coach clients in Canary Wharf, focusing on quality, care, and real results — helping professionals move better, grow stronger, and feel confident again.
