Our Coaches

Marcus Dedina

Co-Founder and Coach, Marcus Dedina lives in Leucadia, Ca. He started his CrossFit journey in Hawaii in 2006, when there were less than 70 CrossFit Affiliates. “I was approached by a couple doing a workout in a park and they asked me to join. After a couple weekends of working out with them, they invited me to their home to WOD in their garage and have dinner. This turned out to be the first location of the now massive CrossFit Oahu family in Honolulu Hawaii and the man that invited me to work out on that first day in the park happened to be a Chief Navy Seal.” He spent many years working as a CrossFit Oahu coach and had the chance to work with and even train many members of the “badass” elite special forces.

Since then, Marcus has owned three CrossFit businesses, coached for nearly a decade, and competed at the CrossFit Regionals. “I owe a lot to CrossFit, as it has allowed me to be far healthier and more focused while also giving me an amazing community to be a part of that I consider family.”

Alex Nabor

Alex "Nacho Friendly" Nabor has what cannot be taught - he cares. Alex is always striving to improve his coaching and make his classes as fun as humanly possible. Alex tried CrossFit at Dynamis three years ago after becoming bored with "regular" fitness. "CrossFit provided me with exactly what I wanted: real fitness, real results and real fun!" he says.

"CrossFit has transformed my life for the better and I want to share it with this community," he says. "It is my goal to help you all reach levels of fitness you’d never imagined, and I welcome everyone to come see just how far you can go!"
