What is CrossFit?
CrossFit is a fitness regimen developed by Greg Glassman over several decades. Glassman, CrossFit’s Founder and CEO, was the first person in history to define fitness in a meaningful, measurable way: increased work capacity across broad time and modal domains. He then created a program specifically designed to improve fitness and health.
CrossFit is constantly varied functional movements performed at high intensity. All CrossFit workouts are based on functional movements, and these movements reflect the best aspects of gymnastics, weightlifting, running, rowing and more. These are the core movements of life. They move the largest loads the longest distances, so they are ideal for maximizing the amount of work done in the shortest time. Intensity is essential for results and is measurable as work divided by time—or power. The more work you do in less time, or the higher the power output, the more intense the effort. By employing a constantly varied approach to training, functional movements and intensity lead to dramatic gains in fitness.
The community that spontaneously arises when people do these workouts together is a key component of why CrossFit is so effective, and it gave birth to a global network of CrossFit affiliates that number over 13,000. Harnessing the natural camaraderie, competition and fun of sport or game yields an intensity that cannot be matched by other means.
The CrossFit program is driven by data. Using whiteboards as scoreboards, keeping accurate scores and records, running a clock, and precisely defining the rules and standards for performance, we not only motivate unprecedented output but derive both relative and absolute metrics at every workout. This data has important value well beyond motivation.
Overall, the aim of CrossFit is to forge a broad, general and inclusive fitness supported by measurable, observable and repeatable results. The program prepares trainees for any physical contingency—not only for the unknown but for the unknowable, too. Our specialty is not specializing.
While CrossFit challenges the world’s fittest, the program is designed for universal scalability, making it the perfect application for any committed individual, regardless of experience. We scale load and intensity; we don’t change the program. The needs of Olympic athletes and our grandparents differ by degree, not kind.

My entire life I have had a passion for fitness and human performance. From my earliest memories I played every sport I possibly could find, constantly finding new ways to compete and challenge myself. In November 2011 I was working out at the California State University, Fresno Rec Center and saw my friend doing a crazy workout he later told me was called “Fran.” He explained to me it was a CrossFit Benchmark WOD and I found myself the next day doing the same workout. After completing “Fran” I was hooked. Somewhere in between finding my breath and the intense burn in my forearms I had found a connection, a connection that would continue to challenge me as I moved forward.
From that point on CrossFit has been a way for me to express and practice my passion for health, fitness and human performance. I believe that CrossFit’s broad definition of fitness makes it inclusive for all people regardless of abilities, previous athletic history and goals. My favorite aspect of CrossFit, however, is the sense of Community behind it. Every day at the box is a new day to hang out with members, learn more about them and develop the bonds we create through finding fitness together.
After I realized CrossFit was my avenue to express myself and my passions, my hunger for knowledge and learning grew tremendously. I worked on cultivating my intelligence and coaching abilities through completing the CrossFit level 1 coach’s course, United States of America Weightlifting level 1 coach’s course and earning a Bachelor’s degree in Kinesiology from California State University, Fresno.
My passion for coaching others in their individual journey through fitness and life has allowed me to build relationships with others as well as given me the chance to do what I love every day. It is a true joy for me and I intend on continuing my pursuit of knowledge and applying what I learn in my life and in others to create happier, healthier, and fit people.

I have always been active, even as a kid I played every sport I could. Enter high school and I played Football, Basketball, and track and field. I was active every day, that being said I have always been overweight, struggling with weight my whole life. After a year of college football I entered the working life and was no longer active, eating bad and sitting around led me to weigh over 525 lbs. shortly after I met an amazing coach who helped me transform my life and lose over 130 lbs. I was doing CrossFit 6 days a week and eating healthy. This helped me feel like an athlete again and reignite my passion for coaching and helping people.
Why CrossFit? What has CrossFit in general done for me? Everything. It’s given me my life back. It pushes you every day with new challenges. New workouts. CrossFit shows you your boundaries. It shows you that you are able to push through those boundaries. It is functional movements. Something like getting off the floor or standing up out of a chair. It’s not a repetitive movement every day. It changes like life changes. CrossFit gives you confidence, whether it’s making you feel like an athlete again or showing you that you are able to achieve a long sought goal. It shows you that you haven’t hit your prime yet. That age is only a number and not a limit. It’s made me love myself again. It has improved me as a father, husband and friend. CrossFit has given me drive. Motivated me beyond weight loss and lifting. It’s the one sport that the person who finishes last gets the most cheers. It’ll pick you up. Help you better not only yourself but others as well. CrossFit has shown me my dream of coaching athletes has not died. I thought my goal of becoming a coach was long past. Now that CrossFit has become such a part of my life I’m refocused on coaching.
In February of 2016 I received my CrossFit Level 1 Certification and in March I became a certified CrossFit Kids Coach. Attaining these has made me want to learn more ways to help kids and adults alike. Learning new techniques and methods to help people reach their full potential and become healthy and fit. My wish list for future certifications includes CrossFit Football and CrossFit Weightlifting courses. I am extremely happy and proud to represent Certus CrossFit and to have been a part of it from the very beginning, in a one-car garage doing workouts in driveways, at schools, parks and swimming pools.
In June 2023 James was in a mountain biking accident causing a spinal injury he is recovering from. For more info and to support James, please visit his GoFundMe.

CrossFit Rowing Trainer
I have been an athlete for as long as I can remember. I grew up doing gymnastics and track. My senior year of high school I was devastated by a series of injuries that ended my gymnastics career and collegiate dreams (or so I thought.) I was soon recruited by the Women’s Rowing Team at the University of Oklahoma as a walk-on. I went from never having touched an erg in my life to completely falling in love with the sport. My boat even went on to earn two Big XII Conference titles for the university.
I found CrossFit in 2011 by happy accident. I was looking for a fun way to train in the offseason. I was quickly hooked once I realized that both gymnastics and rowing could be incorporated into workouts. My favorite part of CrossFit has to be the community and being able to push each other through every workout. You can be complete strangers at the beginning of class and walk out of the gym as teammates.
I love challenging the ideal of what an athlete is. I started coaching because I love helping people discover their own inner athlete. I previously coached at CrossFit 405 and Koda CrossFit Deer Creek in Oklahoma and love continuing my coaching journey in Clovis.

I grew up playing soccer and enjoyed running, anything that kept me moving. After having three kids I became a busy mother and I put my fitness on hold as most mothers do. I moved from Orange County to Fresno in 2017 and CrossFit was recommended to me to give me what I was looking for: functional strength and community. I hit the jackpot when I came to Certus.
As a mother, I want to set a good example for my kids and their health. I’ve learned so much about myself as an individual athlete. Our bodies are capable of so much, there is no limit. In CrossFit, I found my passion, and in Certus, I found a whole new family. I look forward to helping others reach whatever goal they have set.

I played a bunch of sports growing up, soccer, track, baseball, and volleyball. When high school came around and sports got more serious I had to decide on a sport so I stuck with volleyball. Played that year-round, valleys my junior year. I loved the teamwork and community it came with. Outside of practice and games, I always found myself in the gym.
I started CrossFit because of the constant mental and physical challenge it brings you every day. With so many different movements and variations it brings it’s almost impossible to be great at everything, and being someone that loves to always work on myself and things I’m not good at, CrossFit gives me the opportunity to do that every day. On top of that, the workouts are killer, and my favorite thing is to go into that dark mental space in the middle of a workout and be able to push past that to get it done.
There are many great things about Certus; The coaching, programming, equipment, and most importantly the greatest thing is the community. Nothing beats it. No matter what class you go to everyone knows everyone and it’s just a giant family that shares similar goals and interests that come together to get their fitness on and I love it. There’s nothing better than SENDING workouts with your closest friends next to you.
I love the positive interactions it allows me to have with members Seeing the spark in someone’s face when they go from struggling with a movement to being able to perform it properly because of 1) them being an insanely great athlete! and 2) because of some cues I gave them, makes me happy to be able to serve the community in that aspect. “Being of service to others is what brings true happiness” – Marie Osmand

I have played sports my whole life and have always been into fitness and working out. Towards the end of high school, I knew I wanted to do something different related to sports. I found CrossFit through my dad, who had been doing it for about a year at that time. After completing my first CrossFit workout, I was hooked.
After about a year, I wanted to coach others and help them along their fitness journey. I really enjoy helping those around me and pushing them to be better versions of themselves. CrossFit has not only given me an avenue to stay competitive but a way to connect with others and build a great community of friends and extended family.
