Jamie
Percival
Executive personal trainer, boxing coach and the founder behind Complx Health — South Melbourne's first integrated health hub. 20+ years building elite performers, executives and athletes.
Built to integrate.
Designed to perform.
Jamie Percival is the founder and head coach at Complx Health in South Melbourne — a gym that doesn't operate like a gym. He built Complx around a simple premise: training, treatment and recovery should work together, not in isolation.
With more than two decades of experience in personal training, boxing coaching and strength & conditioning, Jamie has worked with high-profile executives, NRL coaches, professional athletes and business leaders — helping them build the physical performance and resilience that demanding careers require.
His longstanding involvement within the Melbourne Storm environment since 2007 — alongside one of Australia's most successful and demanding sporting programs — has shaped a coaching philosophy built on accountability, precision and long-term performance.
Jamie works with a small number of private clients at 101 Moray Street, ensuring every program gets the attention and personalisation it deserves. If you're serious about your performance, he's serious about your results.
