MisterG served 13 years as a Fitness & Wellness Consultant to the City of Calabasas and has instructed U.S. Marines in body conditioning and self-defense. He is the founder of Elements Of G, a private performance space built on one principle:
Fitness. Wellness. Mastery.
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.
During his competitive years, Onadja became a three-time National High School Basketball Champion, earned a place on the Nigerien National Taekwondo Team, and achieved his 2nd Degree Black Belt accredited by the World Taekwondo Headquarters (Kukkiwon) in Seoul, South Korea. His lifelong pursuit of mastery later elevated him to a 10th Degree Master Black Belt and a Doctorate in Oriental Studies.
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. 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, impacting thousands through his innovative methods and unwavering drive to inspire. Among his many accolades, one honor remains especially meaningful: being named by Los Angeles Daily News readers as one of the city’s ‘Most Motivational Instructors. Through every chapter of his journey, MisterG has led by example—energizing, challenging, and inspiring all who step into his presence.
