What is ONE Nation?

We are a CrossFit facility dedicated to the pursuit of excellence through Community, Effective Coaching and Fitness. But, we are also much more…we are a tight knit group, a family. CrossFit is more than just an effective way to workout and get in shape. CrossFit is a way of living life to be your best. This includes training your body mentally and physically, as well as eating appropriately to sustain an active lifestyle. This also includes the camaraderie and support of those around you.

What is CrossFit?

CrossFit prepares you for whatever life may throw your way. Our workouts are designed to maximize your results in the gym and improve your quality of life outside of the gym. The CrossFit program delivers a brand of fitness that is broad, general, and inclusive. Our speciality is not specializing. We are generalists. At ONE Nation, you will learn how to safely, effectively and efficiently squat, lift, press, run, jump, row, throw, and move your body through space. The workouts are challenging yet rewarding. We will help you realize your human potential, and each day that you enter, you will leave better for it. For more information, visit our CrossFit program page.

Is CrossFit ONE Nation for Me?

Yes! CrossFit ONE Nation is for people of all age. We help improve the lives of everyone from children to grandparents and all in between through fitness and fun! CrossFit is universally scalable so everyone can participate. We do movements that you do in your everyday life, such as standing up and sitting down, picking things up off the ground, and putting things over your head. What this really means is, in addition to helping you maximize your athletic performance, we will also help you be better prepared to tackle any daily challenges you may face – from unloading groceries to carrying your little-one down a flight of stairs. We just make sure you do it safely, effectively and efficiently. This is what makes CrossFit so special. No matter your abilities or experience, our coaches will tailor the workouts just for you. Whether you opt for small group classes or private one-on-one coaching sessions, we are confident you will reach your full athletic potential, and have fun in the process.

What’s Special About the Community?

Lots of things separate CrossFit from other programs, but most important is our unique and supportive community. People join for the fitness, but stay for the long haul because of the friendships and bonds they develop within our walls. Aside from building better human beings, ONE Nation works to develop a community of like-minded individuals who support, encourage, motivate, and assist one another in reaching their personal goals. In fact, the communal aspect of CrossFit is a key component of why it’s so effective. It’s not uncommon for an intense training session to be followed by a full on ladies night, bro-session, or both combined! Community is what we are about, we are ONE family working together toward ONE goal, united in fitness – we are ONE Nation! Come join us!
