We can't believe it's been it's already been more than a month since we wrapped up the second annual Chaos Theory Throwdown competition! The day lived up to the hype - fast and furious! Each team completed five workouts in less than an hour, and they brought the intensity for each and every workout. Congrats to all the competitors and our podium finishers!

The Chaos Theory Throwdown will definitely be back in 2027, we'll see you there!

Do Hard Things. Succeeding at any endeavor - fitness, business/work, parenting, friendships, sports, and so on - requires you to be COACHABLE. At Coefficient CrossFit, we create a culture that allows you to embrace a coachable mindset every single day you walk into our facility.

Coaching is the foundation of everything that Coefficient CrossFit offers. The benefits can be obvious and straight-forward, like ensuring that our athletes are learning how to move safely and optimize their workouts, but what’s less obvious is the mentality you develop, and that becomes equally important. Join our community, let yourself be coached every single day, and watch your mindset of coach-ability expand to the rest of your life. Create a habit of learning and improving.

Be Coachable.
Do Hard Things at Coefficient CrossFit.
