The Full Story
Three Decades of
Transforming Lives
For more than three decades, Garba ‘MisterG’ Onadja has dedicated his life to inspiring and empowering individuals to transcend limits — transforming not only their bodies, but their entire way of living. His journey began in West Africa, where he was raised with a profound respect for the discipline and vitality of an active lifestyle — a philosophy that evolved into his lifelong mission and legacy.
While living in France, MisterG envisioned a fitness system that transcended fleeting trends to unlock the true essence of the mind–body connection. His mission was clear: to craft a method that delivered more than results — one that sparked lasting transformation.
More than results — a method that sparks lasting transformation.
That vision became gTonnicks — a uniquely integrated practice rooted in the disciplines MisterG has spent a lifetime mastering and teaching: from classical ballet and gymnastics to the martial arts.
MisterG’s influence spans the globe. Among his many accolades, he was named by Los Angeles Daily News readers as one of the city’s most motivational instructors. He served as an Independent Fitness Consultant for the City of Calabasas for over 13 years, was a member of the Tae Kwon Do exhibition team at the 1988 Seoul Olympics, and was inducted into the USA Martial Arts Hall of Fame in Los Angeles in 2004.
His career includes roles as a self-defense and body-conditioning instructor for the U.S. Marine Corps Detachment Guard and the U.S. Peace Corps. Most recently, he was awarded the Medal of Excellence by a U.S. Army Commander for his powerful motivational work.
