Our Promise

There’s no other studio that delivers a low-impact and high intensity workout the way we do. From our studio aesthetics, our curated music, and our top-notch team of caring coaches, our promise is to deliver an epic experience every time, with no detail left to chance. We believe it’s not just about what we do, but about how we deliver results that truly makes us the most effective workout.

We pride ourselves on being innovative, and that includes the equipment. Our Megaformers® were created as an extension of your body, so the carriage is smooth and light, like driving a luxury car.

Along with the equipment, we add a unique mindfulness element into our classes, because we believe the mind is inextricably connected to the body. Our instructors are trained in meditation to really tap into your mental strength throughout class, because we believe that a Strong body + a Strong mind = an Epic life.



Hardcore. Effective. Efficient. Safe. What’s not to love? Our signature class, using the revolutionary Lagree Fitness® Method, was developed to give you the best possible workout in the shortest amount of time. Use slow movements (to target slow twitch muscle fibers, scientifically proven to burn more fat), resistance training (to build muscle strength), continuous tension (via spring resistance) and constant engagement of your core (on a moving platform) to push your muscles to maximum exertion and keep your heart rate elevated throughout. Stretch your limits as you burn 500-800 calories per class.
