Darren Cook – Level 1 CrossFit Trainer
Hi everyone my name is Darren Cook! I am a coach at Rio City CrossFit. I obtained my CF-L1 Trainer Certificate in June 2023. Prior to becoming a trainer, I had been doing CrossFit for three years and quickly grew a passion for the sport.
From a young age, I’ve had a love for athletics, where I competed in baseball and basketball. Later on, I became involved in other sports such as skateboarding and snowboarding. When I was introduced to CrossFit, I began to notice improvements in my strength and endurance, which made me want to keep coming back for more! Another reason why I've stuck with CrossFit is the community. We have an amazing group of people who strive to support one another.
As a coach, my goal is to provide assistance to each athlete to help them improve their fitness. My main focus is teaching proper form and mechanics. And also, I want to ensure each class is a fun and enjoyable experience!

Jon Sou – Level 1 CrossFit Trainer
I grew up playing basketball from a young age and spent a while trying to find my way at big-box gyms. That eventually led me to running and doing many half marathons, but I was still missing something. I wanted to try CrossFit, and walked into a box a block away from me, not realizing it was the well-known gym Invictus. That was it for me. Over ten years later, I'm still at it.
Along the way I've worked through a severe back injury. Coming back from that taught me more about training smart than anything else, and I've come back stronger than I was before.
Basketball taught me early on that working out is better as a team sport, and that's a big part of what's kept me coming back to CrossFit. I'm a husband and dad first, and that's shaped how I coach as much as anything. Fitness isn't about chasing perfect, it's about showing up consistently for the people who matter most.
Moving back to Sacramento, I was able to join Rio City and have it made it my home for many years. Arthur and Heather are welcoming to everyone and the community has been fantastic! Getting my Level 1 certification was about sharing what CrossFit gave me. I'm looking forward to helping others and making fitness accessible to all.
