However CrossFit soon became his true passion after noticing great improvements in his fitness, speed and power. Trey works hard at building strong relationships within the CrossFit Craigieburn community pushing members to get better each and every day.

Trey says “the ability to get outside of my comfort zone, whether it be in a workout or learning a new movement requires me to consistently get out of my comfort zone which in turn gives me more confidence in my mental capabilities as well as my physical abilities”.
