When you find your why, your limits don't exist

The Premier CrossFit Facility on the South Shore

When you know "why" you want to get stronger, leaner, and healthier, all that hard work it takes to get there doesn’t seem so hard after all. At CrossFit Kells, we’re going to help you find your "why." Then we’re going to push you harder than you ever thought you could go.

And you’re going to love it.

The close-knit community in and around CrossFit Kells is just as important as what our physical gym has to offer. We’ve got people from every walk of life and athletic ability here: teenagers, seniors, moms, armchair athletes and a bunch in-between., who share a common goal of being better.

Our world-class coaches help our members reach their goals safely and effectively, and they have a blast doing it. While we are serious about CrossFit, we don't take ourselves too seriously, which people seem to like. We think you’ll like it, too.


What are you waiting for?


Our 5,000-square-foot facility is located less than four minutes off of Exit 10 on Route 3 in Duxbury, MA. Inside, you’ll find all the space, high-end equipment and experienced coaches you’d expect from the best box on the South Shore.

We’ve got everything: exciting classes, challenging WODs, all the cool CrossFit tools you love (and sometimes love to hate), and so much more. The only thing we’re missing is the most powerful machine of all ... you.

  • You guys rock. CFK has become the 6th member of our family. The people at CFK are my friends, my supports, and my motivators. The workouts are great – at 8:33 p.m. EVERY night we race to our phones to see the next day’s WOD.
