Three decades of champions, warriors and everyday fighters who dared to step through the door.
Bulldog Gym was born in Blacktown, NSW in 1993 — founded by brothers Stuart and Steve McKinnon, following a lifetime of martial arts that started with their father's Shotokan Karate schools in Scotland and Australia.
Stuart began training at age 4, earning his first dan black belt at just 10 years old. After competing virtually undefeated as a junior, he discovered Muay Thai kickboxing at 17 and never looked back. Steve followed the same path, moving from karate to Muay Thai at 15.
The gym stayed in Blacktown for four years before moving to a larger, more suitable facility to accommodate its ever-growing membership — eventually landing in the heart of Castle Hill, where it stands today.
Both brothers trained extensively at Thailand's legendary Fairtex training camp in Bangkok — the gold standard of Muay Thai conditioning. These years forged their technical precision, their mental resilience, and the uncompromising standard they bring to every session.
That experience is what separates Bulldog Gym. The coaches don't just know technique — they've lived it in the ring, across Australia and in Thailand, with real stakes on the line.
Today, Bulldog Gym Castle Hill is a fully equipped Muay Thai and kickboxing facility — complete ring, weights area, cardio machines, bags, speed balls, clean amenities and a team of coaches with genuine fighting pedigree.
The gym caters to everyone — from complete beginners looking for self defence, weight loss and fitness, to serious amateurs and professional fighters preparing for the ring. The standard is high. The culture is welcoming. The results speak for themselves.
