Group Fitness & Kickboxing Classes

Jump To The Free Trial

Come find your tribe and get your sweat on with a group training session.  Sessions are ever-changing to bring new challenges and better results.  Focusing on functional training, group fitness sessions are built upon proven modalities such as TRX, kettlebells, barbells, bodyweight and resistance training in a bootcamp format.  Our group training sessions are open and accessible to participants of all abilities - no previous experience required!

For that extra cardio kick (literally!) we offer our Intro to Kickboxing classes.  High energy and so much fun, Intro to Kickboxing sessions focus on partner drills and padwork.  Open to all ages & stages, no previous experience needed.

The Sweat Box is hands down THE BEST. Christine and Marc are meticulous in every aspect of how they run their modern, clean and safe fitness studio. Workouts are designed to challenge you to push further than you think you can go, and if you ever waiver in that progression they are there to encourage you as you need it.
