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.

Do Hard Things.

Give it a try at our FREE Saturday Community WODs every Saturday at 8:30am https://www.coefficientcrossfit.com/freesaturdays

We are so proud of members Kristie Lee Mankowich Tawny Willis and Jacob Willis for their exceptional performances at Heart Of America Competition this past weekend. They showed up and did hard things, and it seems like they learned a little along the way. Kristie Lee Mankowich literally met her teammates there, and Tawny and Jacob joined forces with friends from another gym. Fitness is fun, and brings people together yall! Way to go friends!!
