How often do you let yourself be coached? For many adults, it's something we miss out on far too often.

But the benefits of being coached are profound - you train yourself to continue learning, improving, and deciphering how to embrace new perspectives.

At Coefficient, every class is guided by an expert coach. By showing up regularly, you'll continue to build the habit of being coachable which will improve your abilities in the gym, but just as importantly, it will improve how you grow and develop outside of the gym too.

CrossFit is the most effective way to develop comprehensive fitness and general physical preparedness (GPP), but only when trained correctly and safely. Coaching is THE product at Coefficient and we don't stray from the critical order of 1) mechanics, 2) consistency, and THEN (AND ONLY THEN) 3) intensity. Failing to follow that order is how injuries and burnout happen, and that's why we are here to keep you on track.

Be coachable. Join us and see for yourself how that will improve your fitness, health, and beyond.

Once a year we send out a survey ✅ to our members, asking how we can make our community better for them. 🤔 Well, you suggested and we delivered. 🙌🏼

Our members told us they wanted more strength and circuit-style training. 💪🏼 They wanted to be more flexible and mobile 🤸and they needed a way to recover. 🧘

So, ALL of our members now have access to FIVE ✋🏼 new classes as part of our Unlimited Membership. 😳😍 We want our community to be as healthy and fit as possible and we’ll never stop working to help you achieve that!

Being uncomfortable is hard, but it's worth it. At Coefficient, we're going to help you create a habit of pushing yourself outside your comfort zone, so you can build a grit to handle anything that life throws your way.

Be uncomfortable. Practice that in a community to keep you accountable and under the guidance of expert coaching.
