CONDITION NUTRITION
THE STORY
From Construction to Coaching Champions
Before fighters trusted me with their careers, I was working on a construction site in Australia. No network, just an obsession with how nutrition could transform performance inside the ring.
I kept hearing the same outdated advice
The reality fighters face is brutal:
Training feels heavier than it should.
Energy crashes at the worst possible time.
Every weigh-in becomes a fight with the scale.
I’ve seen athletes lose their edge, their confidence, even world title opportunities, because nutrition failed them when it mattered most.
That’s why I built Condition Nutrition: a system forged in real fight-week experience, backed by science, and tested under the pressure of world title fights.

HOW IT WORKS
Combat sports nutrition isn’t static, it evolves with camp. I work alongside fighters, adapting strategy as conditions change:
If schedules shift, the plan shifts.
If weight slows, adjustments are made.
If pressure builds, I guide decisions in real time.
This is more than calories, experience we hundreds of fighters at the highest level
