What We Do

At The Sweat Box we are focused on three primary services:  Personal Training, Group Fitness, and Nutrition Coaching.  Many of our members choose to "double dip" and combine two (or even all three) of our services to achieve their personal goals.

Each of our services is broken out below, along with their respective pricing options.

Group Fitness & Kickboxing

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 best part is that our Group Fitness and Kickboxing classes are FREE TO TRY!  We won't ask for any billing info.  Hit the button below to get started.


Personal Training

Tired of wandering the gym floor with little or no results?  Looking for specific results but uncertain how to achieve them?  Need a little extra motivation and accountability?  Consider experiencing a personal training session with one of our Certified Personal Trainers.  We love working with men, women, and teens to help you get fit, stay motivated, build more muscle and feel great about what you see in the mirror.  A healthy body equals a healthy mind.  We can help you reach your goals.

Nutrition Coaching

Habit based nutrition coaching on your terms.  No calorie counting, no restrictions, just good habits for life.

Our programs are delivered primarily online and include everything needed to keep you accountable and moving towards your goal.  You will access the program through the mobile app or your web browser.  You will also have a one-on-one accountability call every week with your coach (over Zoom or FaceTime).

Once you sign up, you will receive an email with the link to access the program.
