Ben Breen

My involvement with CrossFit began in 2011 whilst playing rugby in the Royal Air Force and being introduced to the sport by a team member. After watching many YouTube videos and practicing my snatch technique in front of my bedroom mirror I stepped into my first CrossFit box. In February 2012 I joined CrossFit Nottingham and developed a passion for the training methodology behind CrossFit and completed my CrossFit Level One Certification Course shortly after in 2012. When executed with precision, I believe CrossFit is the best fitness programme available, not only to develop physically but to develop as an individual too.

I became part of Royal Docks in the spring of 2017, splitting my time between coaching, training and working on my degree in chiropractic. I aim to combine my knowledge of CrossFit the training methodology along with my knowledge of human anatomy and function.
