Christian Willis

Growing up in Australia, Christian swam competitively from the ages of 10-15, it wasn’t until just before his 16th birthday when he watched pumping iron for the first time, that his life changed forever. Ever since then the gym has been his passion and a major part of his life for over a decade, his ever-growing hunger for knowledge led him to train in multiple styles of lifting including periods focused on bodybuilding, powerlifting and hardstyle kettlebells, while also training Brazilian jiu-jitsu for a number of years, rock climbing, western boxing, multiple types of yoga and regularly open sea swimming. This love of training led him to pursue a degree in sports science, it was there that he found his niche, completing his thesis on the effectiveness of heat exposure coupled with cold exposure as a tool for recovery and maximising athletic performance, the first of its kind carried out anywhere in the world. This long road then led him to personal training people from all demographics from athletes to regular folk until he found Crossfit. He then fell in love with the style of training and made the decision to leave the research behind and pursue a career in coaching.
