Hailing from the UK, Mainer played semi-professional football until finding CrossFit at university. A longstanding member of the Dubai CrossFit community, Mainer started coaching because of his passion for helping other people learn and progress. His specialty is coaching weightlifting, and he loves seeing the gains his clients make in strength, coordination, and power as they learn and master the Olympic lifts.


A self-described “athletic nomad,” Mainer has accumulated over 2,500 hours of coaching in 6 different countries, including a year-long stint as a roving CrossFit coach at gyms across Asia. When he’s not coaching, training, or traveling, he can be found at his computer writing articles for AdventureFit Travel & Fit East magazine.


Mainer does not apologize for being a ginger.
