A champion from the start
Before coaching others, Garba “MisterG” Onadja built his own foundation through competition, discipline, and performance.
He became a three-time National High School Basketball Champion, earned a place on the Niger National Taekwondo Team, and achieved his early black-belt ranking through Kukkiwon, the World Taekwondo Headquarters in Seoul.
Those competitive years shaped the principles that still define his coaching: precision, control, resilience, discipline, and purposeful progression.
Over the decades, that athletic foundation evolved into a coaching system centered not on random workouts, but on building a body that is stronger, more capable, and more reliable over time.

Three Decades of Transforming Lives
For more than three decades, Garba “MisterG” Onadja has coached individuals to become stronger, move with greater control, improve physical confidence, and build bodies capable of performing well over time.
His journey began in West Africa, where sport, discipline, and physical mastery were central to his early life. Basketball, martial arts, and years of competitive training established a foundation that would later shape his approach to coaching.
While living in France, MisterG began developing a movement philosophy centered on the connection between muscular engagement, intention, posture, balance, and control.
That philosophy evolved into gTonnicks®, an integrated movement system influenced by disciplines he has spent a lifetime practicing and teaching — from martial arts and conditioning to classical movement, balance, and body control.
After establishing himself in Southern California, MisterG became an Independent Fitness Consultant for the City of Calabasas for more than thirteen years and continued building a private clientele spanning entertainment, business, athletics, and everyday individuals committed to performing at a higher level.
Today, his coaching is centered on a simple principle: strength should serve your life. Every session is designed around the individual; their body, goals, abilities, lifestyle, and the capability they want to preserve for the years ahead.
A Legacy of Excellence
MisterG's career has been shaped not only by athletic achievement, but by decades of teaching, leadership, service, and the pursuit of mastery.
From martial arts and community fitness to work with military personnel, his experience reflects a consistent standard: develop capability, lead with discipline, and help people discover what they are capable of becoming.
That commitment has earned recognition across martial arts, public service, fitness, and motivational leadership.

More Than Exercise.
A Method for How the Body Performs.
Created by MisterG over decades of coaching, athletic practice, and movement study, the gTonnicks® Method is built around a simple principle: movement becomes more effective when the body performs it with intention.
Rather than simply moving through repetitions, gTonnicks® develops an awareness of how the body engages, stabilizes, controls, and completes each movement.
Strength, balance, posture, stability, coordination, body control, and muscular engagement are developed together; creating training that is purposeful, precise, and adaptable to the individual.
At the foundation of gTonnicks® is IPCM — Intentional & Purposeful Contraction of the Muscles: teaching the body to remain actively engaged throughout movement, rather than simply moving from one repetition to the next.
Intention
Every movement has a purpose. The body is taught to engage deliberately rather than move passively through exercise.
Control
Quality of movement comes before quantity; developing stability, precision, awareness, and command of the body.
Capability
Training should improve what your body can do: building strength, movement confidence, performance, and long-term physical capability.
Stronger · More Capable · Built to Last
Work With MisterG Strength. Performance. Longevity.
Private coaching begins with understanding where you are, what you want your body to be capable of, and what may be standing between the two.
Whether the goal is greater strength, improved movement, renewed athletic capability, body composition, or staying exceptionally capable as you age, the process is personal from the beginning.
MisterG brings decades of coaching experience, athletic discipline, and the principles of the gTonnicks® Method into a private training experience designed around your body, your objectives, and your lifestyle.
Just focused coaching built around you.
