Garba “Mister G” Onadja

For over three decades, Garba “MisterG” Onadja has made it his mission—both personally and professionally—to inspire and empower individuals of all backgrounds and fitness levels to transform their bodies and their lives. His journey began in West Africa, where he was raised with a deep respect for the power of a healthy, active lifestyle—a philosophy that became his life’s calling.

While living in France, Mister G envisioned a revolutionary fitness system that would go beyond trends and tap into the true essence of mind-body connection. His goal: to create a method that delivered not just results, but transformation. That vision ultimately became gTonnicks—a uniquely integrated workout drawing from the disciplines Mister G has mastered and taught for years, including classical ballet, gymnastics, and martial arts.
