What Is Crossfit?

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.

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. (Courtesy of CrossFit Inc.)

John san Filippo

John discovered the sport of CrossFit as a 17 year old by stumbling across the CrossFit games on ESPN, but wouldn't step foot into a CrossFit gym for 5 more years. After a high-school career that culminated in being named an All-American in wrestling, John attended Wesleyan University, where he played football and wrestled. After his collegiate athletic career was cut short by two shoulder surgeries, he decided that he was interested in starting CrossFit, and began an individualized program with CrossFit Milford, in Milford, Connecticut. The physical therapist on staff at Milford worked in conjunction with the coaches to provide him with the proper progressions and rehabilitation from his surgery in order to ensure that his repaired shoulders would function properly. This experience convinced him that CrossFit can play a vital role in helping overcome injuries and dysfunction in order to lead a more fulfilling life, and lead him to pursue a career in the fitness industry.

When he's not at Bladium or working out, John can be found in the mountains, on his motorcycle, or wondering how he managed to spend so much money at his local bookstore on such a short trip. He is pursuing a competitive career in CrossFit and Olympic Weightlifting.

tomi ahearn

My name is Tomi Ahearn and I have been doing Crossfit since 2014 when I moved to Denver from my hometown of Missoula, MT.  I quickly fell in love with the variety of Crossfit and how my body transformed and became stronger.  I am formally educated in Mathematics with a degree from the University of Montana.  I currently teach high school students math, host trivia and coach Crossfit.  I have been active all my life from running (long distance…I can’t sprint with my wiener-dog legs), to volleyball (libero of course…vertically challenged), and even lettering in wrestling.  My other talents include: solving a Rubik’s cube, being the loudest teammate at Crossfit competitions, knowledge bowl tournaments and finding the perfect meme for any situation.  I am excited to have the opportunity to coach at the Bladium and contribute the positive atmosphere created by all who work out here.

Aaron Brill Crossfit Coach

I 'found CrossFit' when I was assigned from patrol to the police academy as an instructor in 2009. I was the typical big arms/little legs cop. The Captain of the academy saw the arms and said, "You're a big guy. You're going to be in charge of fitness. Apparently we do this CrossFit thing so get certified." 

I coached everyone that walked into the academy for the next year, whether they wanted it or not, went to some more seminars then opened my own gym in 2010. I knew of, and respected, Scott Olson so in 2016 I joined Bladium CrossFit.

Emily Wall.jpg


Emily began coaching weightlifting in 2011 while teaching high school science in Orlando, Florida. After moving to Colorado in the summer of 2015, she earned her CF-L1 and began coaching CrossFit. As an educator, coaching quickly and naturally became her full time job.  In her younger years, Emily was a competitive dancer, with an affinity for tap, but the subjective nature of the sport fueled her involvement in her next athletic interests, weightlifting and distance running.  She has always enjoyed the objective measure of success in these sports; the numbers on the clock and the numbers on the bar never lie, and this objective and measurable nature drove her to CrossFit. 

Additionally, her experience in coaching youth weightlifting fueled her desire and love for coaching CrossFit. She was always inspired by her athletes’ ever-growing confidence and the effect that the sport had on their lives outside of the gym, and that’s what she loves most about CrossFit.  Beyond the numbers measured at the gym, she finds no greater passion than helping individuals of all ages improve their physical, and more importantly, their mental health, through the community of CrossFit.

Michael Sevilla Coach

Michael Sevilla

A few years ago while practicing Krav Maga, Michael started to look for a way to cross condition and improve overall strength, stamina, and flexibility. Starting with MMA inspired workouts he added yoga, bootcamp cardio and body weight workouts to my overall routine. In late 2010 he attended his first CrossFit class. Even though he could barely breath after the 12 minute workout, he was hooked. Based on his love for all things CrossFit he decided to become a CrossFit coach and share that passion with others who want to transform their lives and improve their fitness.

In 2016 at age 26, Jason weighed 65 more pounds. Motivated for change, he explored exercise as a healthier way to alleviate stress than eating pizza and drinking beer. Although he initially saw results, he struggled to find a program that didn’t get stale, and he struggled with low back and hip pain, which caused him to have long absences from the gym. Reaching his thirties, Jason believed that being somewhat over-weight, in pain, and being generally stressed-out was just part of getting older. Then, in 2013, Jason decided to take a friend’s advice and give this CrossFit thing a try. He was hesitant. He had pictured going to a gym where they just told him to throw a bunch of weight around and leaving on day one with debilitating back pain. To his surprise, he discovered a program that was welcoming to people of all fitness levels.

He considers himself in better shape now than at any point in his twenties. After discovering what a truly remarkable and life changing program CrossFit is, Jason knew he had to give back to the community. To pursue this goal, he obtained his Level 1 CrossFit certificate in 2016.

He is passionate about teaching CrossFit to others and showing what a great program and welcoming community there is here at Bladium. He also loves spending time with his wife and two-year-old son, snowboarding, and working to achieve his goal of climbing all of Colorado’s fourteen thousand foot peaks

In 2013 when she had her son, Jackie started to go from chubby to “fat”. She and her husband went to Maui at the end of 2014 for New Year’s, and she couldn’t buckle the seat belt on the plane – getting bruises on her thighs from where the seat dug in. She weighed 310 lbs. After getting back, she evaluated what was important - being be able to play with Rainer, and walk up stairs without feeling like dying. Changes needed to be made: starting with changing her diet a little, and then let a friend talk me into trying CrossFit here at Bladium. She couldn’t do a full squat, let alone even knew what a burpee was and she’d never even touched a barbell before. Jackie fell in love with CrossFit, the community, the intensity, and the empowerment. CrossFit, coupled with solid nutrition, made it possible for Jackie to lose 120 lbs.

Soon she realized that she needed to coach: to give back to the community that had given her so much, and to pass on the knowledge that fitness can be fun, nutrition doesn’t have to be a “diet”, and that your mindset is where everything begins. She’s excited to be coaching at Bladium, where it all started for her! Jackie no longer tries to blend in, but loudly and unapologetically his herself, and inspires others to do the same. She truly believes that fitness can help strengthen the mind, body, and soul, and is passionate about helping teenagers and adults unleash a great untapped power they hold inside themselves.

Jack was born and raised in Ireland but moved to Denver last summer to be with his American wife. He began his fitness journey with rugby at an early age, eventually moving on to represent his province of Munster and to captain of his senior club by the age of 19. Forced to retire from rugby early due to a serious injury, Jack quickly realized that he needed to find something else to fill the void left behind.. He began training and competing in cycling, distance running, and triathlons. Jack started CrossFit to supplement his endurance training, but it wasn't long before he fell in love with the philosophy and began to CrossFit full-time. Then and now, Jack's loves the way CrossFit challenges him daily across many domains as well as how it helps him feel part of a team once again.

Outside of the box, Jack is a middle school science and math teacher. His passion for teaching and helping with others is what led him to start coaching; he has been coaching CrossFit since 2014 when he helped set up a CrossFit box in his local town. He thrives on helping people to be better versions of themselves, meet their goals, and achieve more than they ever believed possible.

Chandelle Stone

My love for health and fitness started over the course of my military career. While serving overseas, I first experienced CrossFit on Bagram Air Base in Afghanistan. It was a whole different level of challenge for the body and mind that I never before experienced, and I was instantly hooked. Over the course of my military career I sustained a couple of minor injuries that have turned into the best gifts allowing me to develop greater techniques for recovery, mobility, and overall functionality. It is now my passion to teach others how to live healthy, happy, and fit lives. Outside of coaching I am a full-time student at CU Boulder studying physiology. My plan is to continue my education by applying for medical school in the next couple of years- ultimately I’d love to go on to complete a Phd and MD in neurology. 

I enjoy learning to the max and tell everyone I’m the coolest nerd you’ll ever meet. I listen to lots of Podcasts to discover esoteric and controversial topics that challenge and expand my own beliefs and consciousness.

I’m an open book, please ask me anything! Look forward to helping everyone on their fitness journey!
