Our 'WHY'

The pursuit of excellence through commitment and unrivaled efficacy guides our every move at G-Theory CrossFit.
Age and athletic ability don't matter here. YOU matter here. What is important to remember is that attitude is everything and determines how active we remain to be while we age. It is the effects of a sedentary lifestyle, not age, that cause functional decline and illness, and quality of life is significantly better for those who remain fit and active throughout the course of their lifespan. Becoming and athlete and remaining an athlete creates a 'survival advantage.'

We've created a safe place of community and personal growth, from the inside out.

Whether you come in for one trial visit, or become a lifer, you will walk away with an experience that will make a difference in your day, and hopefully your life. Everyone has a home at G-Theory, no matter your age, race, gender, or athletic ability.

EXPECT unparalleled coaching through compassion, empathy, and understanding while being pushed harder than you've ever been pushed. Challenged in ways you've never thought were possible (mentally, emotionally, and physically). The result: the strongest, best version of yourself-a complete transformation and better quality of life. Our mission going in to every workout is to leave each member injury free, prepared to tackle any challenge in life they may face that day, and hungry to come back for more through the mastery of the fundamentals; good mechanics with consistency leads to intensity. THIS is the magic and this is how we all become 'BETTER EVERY DAY' at G-Theory CrossFit.

COME IN FOR A FREE TRIAL and see what you think. It's easy. Click on the NEW ATHLETE TAB and fill out the required information, and sign the waiver. As soon as you do, we will receive your information and will be able to approve you in our system. From there you will be able to log in and sign up for a class under the class schedule tab. We can't wait to meet you and welcome you to your 2nd home, where friends become family, and transformation is undeniable.

I've been doing CrossFit for about two years now and have tried out several different gyms. G-Theory is outstanding-- coaches are more attentive and knowledgeable about proper form and mobility than any other gyms I've tried. Lots of personal a

Coach Ginger, owner of G-Theory, has literally changed my life. As a 66 year old woman, I entered Cross Fit with some trepidation. It didn't look like other gyms. There were no machines plugged into outlets and all around me were weights, barbel

I am a new member. I was nervous to start, having never done CrossFit before. I was also intimidated, worried about my ability to do the challenging workouts. I am writing to share while the workouts are still extremely difficult for me, I feel l
