Meet our TEAM.
Crucible is built around the quality of its coaching. The people who write the programs are the same people on the floor.
HEAD COACHES
Liam opened Crucible to raise the standard of coaching; where technical precision matters and progress is built through true coach-athlete partnership.
With over a decade of experience competing and coaching in strength and conditioning, CrossFit, Olympic weightlifting, and Cricket, he brings experience in one-on-one coaching, small group training and competition preparation.
Liam oversees programming, athlete development and competition pathways from beginner to advanced. He also has a big passion for working with people to simply build healthy and capable bodies. His guiding principle: keeping classes small so individuals stay big.
Crucible is the outcome of the standard Liam refused to compromise on: focused, performance-driven and committed to excellence.
