Ronnie is a well experienced trainer of both private and groups. He has a passion for fitness and health and is constantly absorbing more information that will benefit his clients.

He is a competitor. A hockey player for over 20 years since the age of 3 he learned the value of winning at all costs. Having a father that owned a bunch of old “fix up” houses he forcefully learned the value of hard work. Ronnie knows that anything is possible. He does not accept and is highly intolerant of anything that goes against that viewpoint.

Before adapting CrossFit and other group classes into his gym (established in 2006) Ronnie had his own private training gym in Los Angeles focusing on high intensity training. He now focuses his efforts coaching top level CrossFit athletes. his specialities are in Diet, Biomechanics training, WOD strategy, and performing maximally at redline levels.

Nina Sugamori

Nina Sugamori is currently:

-Level One CrossFit Certified Trainer
-CrossFit Kids
She is also AFAA certified as a Group Exercise instructor and Personal Trainer.

She has taught aerobics and fitness since 1989 and yoga since 1998. Class formats included belly dance, seniors, sculpting, step, high-low, kickbox and exercise ball.

Her involvement in sports began in junior high with cross country running, soccer and softball. Later she pursued body building in Venice Beach at World’s Gym operated personally by Joe Gold himself.

She originally was introduced to a traditional 6-day/week split routine by Arnold Schwarnegger’s cousin Jo Jo. She credits her muscle mass from the split routine for allowing her to survive a motorcycle versus drunk driver collision in 1983 that took her right biceps, radial nerve and one inch of her right humerus.

Brief ventures into Muay Thai, acrobatic yoga, the Alexander Feldenkrais technique, adult gymnastics, and snow boarding have taught her the value of integrated neuromuscular synchronization and proprioceptive skill development.

Her childhood with her painter/sculptor grandmother and bachelors degree in mechanical engineering have given her a keen eye for refined observation of body mechanics and the applied physics of humans executing exercise.

She has taught as many as 26 classes per week which is a form of endurance training.

Nina has an artist’s view of the human form and considers physical training to be a sculptor’s tool for perfecting nature’s living art work. Functional training as CrossFit exemplifies is the most direct route to a balanced enviable physique that performs optimaly and reliably.

At age 16 Nina had an in depth knowledge of human anatomy

Nina coaches WODs, offers one-on-one CrossFit Elements, has extensive experience with scaling and provides assisted torque and stretch sessions.

Zacq has a well-established blend of interpersonal skills and familiarity to sports and fitness combined with a personal philosophy that is foundational to good coaching. He conducts himself with two key ideas in mind:

1] Kaizen: Continuous self-improvement
2] The Golden Rule

He arrives to Downtown LA with years of coaching/sports experience:
1] 11 years football
2] 11 years wrestling

4] 4 years teaching kids swimming
5] 2 years study with a strength & conditioning coach (PCC)

Jason Cole

Jason is a Level 1 CrossFit instructor.

Prior to his involvement with CrossFit Jason was a competitive swimmer, swim coach and instructor, and Los Angeles City lifeguard. While on land he trained and competed in Jiu-Jitsu, receiving his blue belt (BJJ) and another blue belt (Quantum Jiu-Jitsu). He also dabbled in MMA. His first exposure to “constantly varied, functional movement performed at high intensity” was watching fellow Banana Slug Greg Amundson (original CrossFit firebreather) slam med-balls into the asphault and do kipping pull-ups and thinking “what the hell is this guy doing?” and “I have to try that.” The rest is history. Jason only wishes he had encountered CrossFit earlier, as it would have made pulling folks out of the water, or into armbars, that much easier.

Jason is a graduate of UC Santa Cruz and USC. When he’s not fighting through WODs (or helping clients do so) he’s fighting for justice in the courts.
