The Workouts

Experience The Difference.


Credentialed & Caring Trainers.

Whether you’re a beginner or expert, our trainers keep you safe, challenged, and smiling throughout class.

Everyone is a VIP.

Classes are big enough to be high energy, but small enough so trainers can teach proper form and modify for individual needs.

Smart & Complete Programming.

Classes combine HIIT, cardio, and strength training to deliver the most efficient workout with the best results in 50 minutes.

Every Day is Different.

While every class has a total body focus, our programming varies daily to prevent fitness plateaus. You’ll progress with each and every class and look forward to the next one.
