I founded 5280 CrossFit after turning my own health around with CrossFit in my late 30’s. Now I get to help others achieve their own health and fitness dreams. Whether you have your sights set on The CrossFit Games, or just want to stay active with your kids (or both, like me!), I can’t wait to help!

Why 5280 CrossFit?

One Goal: Plenty of Options

Our aim is to discover the right path to a healthy life for you! Many of our members enjoy expertly coached CrossFit group classes!

Our approach is to find the right path to help you reach your goals effeciently and effectively.

This Is Not Your Typical Gym

Do you hate working out? Then you’ve never worked out with us! Starting CrossFit can feel like a big step, but we promise that our tailored programming, experienced coaching, and sense of humor will change your opinion about working out forever!

Living our Passion

We love introducing absolute beginners to fitness just as much as we enjoy creating new challenges for our most experienced members. Your health is our passion and our mission is to make fitness a fun, collaborative experience.

What Are People Saying about 5280 CrossFit?


My husband and I started going to 5280 in May and over the past 6 month, this place has changed our lives! We are in the best shape we’ve been in for a long time! We owe everything to the coaches for making working out fun (and safe – there is so much focus on good form) and the members for being awesome and encouraging. Love this place!

5280 Crossfit has become a community for myself and my husband. I have never wanted to “go work out” before, but I find myself looking forward to my workouts. The coaches, members, and the relaxed atmosphere keep me coming back for more. I have never stuck with a gym or workout routine more than a couple months until I started here!

Jessica K.

The amazing coaches at 5280 Crossfit foster a warm and welcoming environment. The sense of community that develops over time is motivating as we cheer each other on in our milestones of fitness. I am proud of my accomplishments and am hungry for MORE!!! I would recommend 5280 Crossfit to anyone looking for a healthier happier life.

Brandon P.

From the minute I started at this gym I felt welcomed. All of the coaches are so friendly, knowledgeable and truly there to help. The community is kind and caring and supportive. The gym itself is super nice and clean inside! I love being a member at 5280 CrossFit. Highly recommend this place for ALL skill levels! Jenna C.

5280 Crossfit has changed my life – it is not just about lifting weights or losing weight, it is about being healthy and physically able to REALLY live life. I drive past a dozen other gyms to get to 5280 because the coaches are fantastic and the amazing group of people who work out here are super supportive. It’s motivating. It’s fun. Try it! Lori G.

5280 CrossFit has turned working out from something I felt like I “should” do to something I look forward to literally every day. Why?

As a runner, I found a welcoming atmosphere to those without a strength training background, and outstanding coaches who consistently give you encouragement and actionable feedback on your technique. More importantly, they emphasize doing things the right way, safely.

Frequently Asked Questions

Myths About Exercise

I have an injury, so I can’t workout.

Strenth training will make me bulky

I’m not fit enough to start group classes.

I don’t have time to workout.

Exercise is just for young people.

Do I Need To Be In Shape First?

Absolutely not. The best way to get ready for CrossFit is to do it! Most of our members had never done CrossFit before joining 5280.

Is CrossFit Safe?

Yes. CrossFit utilizes everyday fundamental movement patterns. Our primary mission is to help people learn the mechanics of fundamental movements; establish a consistent pattern of practicing these same movements; and, only then, ratchet up the intensity of workouts incorporating these movements.

‘Mechanics,’ then ‘Consistency,’ and then ‘Intensity’– this is the key to the effective and safe implementation of CrossFit.

Our Nutrition Program is designed to provide individuals with an easy, science-based approach to nutrition and wellness. Imagine the confidence you could have walking into the grocery store or a restaurant knowing exactly what you should eat to feel and look great!
