I’m Chris Sutcliffe, a personal trainer in Leeds, I founded CSS Fitness in 2015. I’ve always loved coaching people and helping them achieve great things, so I decided to make it my life.
I have dedicated my career to coaching since leaving school at 16, building more than two decades of experience helping people transform their health, wellbeing, and quality of life. Now, at 38, I remain extremely passionate about empowering others to make significant improvements to how they look, feel, and live their lives.
Complementing my practical experience, I spent 6 years studying sport, development and fitness through further and higher education.
