OUR TEAM
HASSAN AIAVA
KICK BOXING | STRENGTH & CONDITIONING COACH
With over 20 years of experience in the field of strength and conditioning, I bring a unique blend of expertise and passion to help individuals achieve their full potential. As an accomplished athlete, I’ve had the honour of competing at the highest level in four different sports, representing my country with pride.
As an exercise physiologist with over a decade of experience, I possess a deep understanding of the human body and its capabilities. My expertise extends beyond physical training, as I’m dedicated to empowering individuals who have faced personal struggles that hindered their progress.
My mission is to provide personalised guidance, support, and motivation to help others overcome obstacles and reach new heights. I believe that everyone deserves the opportunity to excel, regardless of their background or circumstances.
As I always say, “We rise and we will fall, thus we will meet our fate together in our relentless pursuit of excellence.” I’m humbled by the blessings I’ve received, and I’m committed to paying it forward by making a positive impact on the lives of others. Alhamdulillah for everything. - Hassan Aiava
GRANT TASSIE
BOXING COACH
Tassie is a third-generation boxer who’s been around the sport his whole life. He had a strong amateur career representing Australia and was part of the AIS. As a pro, he stayed undefeated and was based in Sydney, training under legends like Johnny Lewis, Jeff Fenech, and Billy Hussein. He learned from the best and now brings that knowledge into his own unique coaching style.
Throughout his boxing journey, Tassie sparred 12 world champions, including big names like Kostya Tszyu, Anthony Mundine, Vic Darchinyan, Billy Dib, and Daniel Geale. That kind of experience shows in the way he trains others.
As a coach, he’s helped guide fighters like Luke Jackson—who he trained for 14 years and took all the way to the 2012 Olympics and a professional world title shot. He also coached Bo Belbin, who stayed undefeated until he faced Nikita Tszyu live on Fox Main Event.
Tassie brings serious knowledge, energy, and passion to every session. Whether you're just starting or already fighting, he'll help you sharpen your skills, improve your technique, and get in great shape.
