Meet Jack

Founder & Head Coach

‘I started training seriously when I was 14 years old under the mentorship of my school PE teacher, GB Commonwealth Games athlete Julia Bennett.  Athletics and football were my obsessions, but my ultimate dream was to compete in the Olympic Games.  This dream was within reach until the age of 16 when injury led to 5 years of unsuccessful operations, endless physiotherapy and some very miserable dark times.

At 18 I started my degree at Brunel University and discovered that weight training did not exacerbate my injury.  It is at Brunel that I watched the strength & conditioning coaches work with athletes like Linford Christie and Usain Bolt and this cemented my path to becoming a certified fitness trainer, strength coach and soft tissue therapist.

My unique skill-set has given me opportunities all over the world. I’ve worked with A-list Directors and movie stars. I’ve travelled the globe with hedge fund CEOs and successful entrepreneurs. I’ve trained a number of high level athletes too. But most of all, I work with regular people like you and me.’
