Let’s Work Together


Ryan Watkins, Pro Overseas

"Coach O is the definition of a real trainer, his approach to training athletes is multifaceted. Combining strength and agility work off the court, with moves that translate to in game situations on the court. Personally Coach O has helped me become more versatile with my game and what I have learned from him has played a pivotal role in my success at professional level."

Namon Wright, University of Missouri

"Coach Olin has helped my game tremendously on and off the court. Showing me what it takes to be a complete player and helping mentor me off the court. With every workout he demands the best out of me and the rest of his players which helps better our game. He is one of the best guys in the game."

Jordan Dallas, Weber State University

"Coach O help me take my game to another level it helped me get stronger to finish at the rim and finish plays in the post. Also helped my ball handling working on my weak hand. All these things helped me become a better basketball player and contributed to me getting a division one scholarship."

Roman Davis, University of California at Berkeley

"Coach O workouts are the foundation of my basketball identity. Without his training and workouts I wouldn't be close to where I am now. All other workouts haven't come close to what he taught me."

Imani Boyette, University of Texas/Atlanta Dream

"Olin Simplis is a great trainer. He has not only grown my love for the game but he makes working out and getting better competitive and fun. I started working with him in high school once I began to take basketball more seriously. The first thing I do when I return home from school is work out with O. As I enter my senior campaign at the University of Texas at Austin, with hopes and a realistc possibility of playing professional there is no doubt in my mind I could not have made it thus far without Olin.p>

The hard but yet beneficial work that he puts you through in his workouts makes the transition to an in game setting that much more easier.

When college didn’t go as planned, Olin played professionally in South America before leading the Belizean National team to a gold medal in 1999. He then shifted his focus on being a father to his son, Kahlil Simplis, and turned his passion into an opportunity to mentor his son and future generations of ballplayers.

GirlsRock is Olin’s newest venture, launched to engage and enhance the professional lives of girls in basketball.

GirlsRock does not only lean into training fiercely competitive female players, but also provides the mentorship, professional guidance, and commercial placements that they deserve. With more than 20 years of coaching experience, training precision, and expertise, Olin is considered one of the most recognized basketball trainers on the west coast. As a personal trainer, Olin’s focus has been on taking a systematic approach to his client’s goals, while simultaneously rectifying muscle imbalance that will help with long-term injury prevention. By formatting a comprehensive training program, Olin targets fitness goals such as fat loss, muscle tone, bodybuilding, and overall health and wellness. He delivers transformative results through fun and creative workout sessions, not your routine gym workouts.

He works with young athletes, celebrities, corporate executives, collegiate, and professional athletes.
