X3 head coach Michael Liberzon is a triathlete, distance runner, NCCP trained triathlon coach, certified personal trainer, and a certified kettlebell instructor. His engineering degree lends itself well to a scientific approach to training.

Michael has been involved in endurance sport for 12 years. His passion for the sport and drive for continuous self-improvement was a natural fit for coaching, so he quit his job as VP of a medium-sized construction company and founded X3 Training in 2013. Since then, Michael has worked with dozens of clients: from first-time triathletes to serial marathoners looking for their first BQ, to obstacle course racers, and ultra-distance competitors. 

He has coached cycling for the Toronto Triathlon Club (the largest adult triathlon club in Canada) since 2013. In late 2013, he accepted the role of Club Director of Training. He held was on the board until late 2015. 

That same year, Michael opened the X3 Training Lab. This facility is all about the pursuit of endurance sport excellence. At the Lab, we combine power-based indoor cycling workouts with the resilience and power development of our strength and mobility program to build a faster, stronger, more resilient athlete.
