OUR
STORY
Gnarl·y :(ˈnärlē/ )- something or someone awesome, cool, excellent, wonderful, amazing, radical, incredible, tough, great, intense, extreme, or fantastic.
Gnarly Fit is a concept that has evolved over the last 7 years. Health and fitness has been a passion of ours for over 13 years and we have worked on and off in the fitness industry throughout that period of time. It has been a goal that one day we would open up our own fitness facility that embodies our values to help create the ultimate environment for one to come and better themselves. Rather its to lose weight, gain weight, look better, feel better, stress relief, or making friends, Gnarly Fit has been designed to be the place where one can come to work to be their best selves.
It has been a passion of ours to design our own gym wear that reflects everything we stand for. All of our apparel is custom cut and designed to make you look good, feel good, and have the ability to withstand even the toughest workouts.

Jesse DeLavern
Owner
B.S. Exercise Science
NASM Certified Nutrition Coach
Bodybuilding Contest Prep Coach
HYROX Coach
Born and raised in Plainwell, Michigan, Jesse has been an athlete his entire life. In high school, he competed in soccer, track, cross country, and swimming, while also pursuing snowboarding, surfing, motocross, and bodybuilding — where he became a multi-show winning competitor. His passion for performance and training led him to graduate from Western Michigan University with a Bachelor’s degree in Exercise Science.
Jesse’s career began in bodybuilding as both an athlete and prep coach, guiding competitors to the stage with proven systems for training, nutrition, and mindset. Over the years, his vision expanded beyond bodybuilding into a multi-faceted approach to fitness and community building.
Today, Jesse is the owner and head coach of Gnarly Fit, a one-of-a-kind training facility in Kalamazoo, Michigan. The gym is home to Gnarly60, a signature functional fitness class that follows Mayhem Affiliate Programming and it blends barbell strength, conditioning, and skill work in an accessible but challenging format. Jesse is also a dedicated HYROX and GNARLY60 coach, and Gnarly Fit is proud to be one of the only official HYROX affiliate gyms in Southwest Michigan, preparing athletes for the unique combination of endurance and strength that HYROX demands. He continues to coach bodybuilding contest prep athletes, carrying forward his roots in physique sport with a modern, evidence-based approach.
In addition to coaching, Jesse founded Gnarly Vision, the creative and media branch of Gnarly Fit. Gnarly Vision produces professional event coverage, behind-the-scenes storytelling, and promotional content for athletes and brands. The Gnarly Fit YouTube channel is the hub for long-form storytelling, including athlete features, event coverage, and the ongoing Gnarly Fit Chronicles series.
Gnarly Fit also extends into lifestyle and performance apparel, with custom collections that reflect the culture, grit, and identity of the community Jesse has built.
With decades of athletic experience, a deep foundation in exercise science, and an entrepreneurial drive, Jesse is building more than a gym — he’s creating a movement that fuses fitness, media, and culture into one vision: to inspire, connect, and push people to be their very best.

Michael Collier
NASM Certified Personal Trainer
Precision Nutrition Certified Nutrition Coach
Functional Movement Systems Certified- FMS 1/ SFMA 1 & 2
ISSA Certified Kickboxing Instructor
My fitness journey started early after seeing the movie Karate Kid. The scene at the end where he wins the trophy, has a cute girlfriend, and everyone is cheering…I was thinking, “Sign me up!” From there I would go on to compete in local, state, and national level competitions before opening my own dojo and teaching while attending Western Michigan University.
I maintained my fitness as I graduated from WMU then went into law enforcement and after years of working night shifts, work stress, and life events like getting married, having children, and all of the other things, found myself not prioritizing my health and getting more and more out of shape.
Then in my early forties, and 70 pounds overweight, I finally had enough. I got winded climbing a flight of stairs, lost my self confidence, and felt trapped in my own body. It was time to make a change. I spent years getting myself back in shape while trying every fad diet, workout program, and shiny new gadget, until finally developing a program that would work for my goals, my schedule, and my lifestyle.
However, I knew that if I wanted to keep my progress, that I would need to be held accountable. And, that’s why I became a personal trainer. Knowing that no one wants to work with a personal trainer that doesn’t look the part or practice what they preach was the accountability piece that I needed to keep me in shape. Now, I love helping other people do the same thing, whether they’re finding fitness for the first time, or regaining their health to become the best version of themselves.
I have a passion for my athletes to achieve their goals, whether it’s a weight loss or strength goal, participating in their first 5K race, or just feeling and moving better now and as they get older. I want them to have an improved quality of life in every aspect.
