We are a small gym focused on building a great fitness community in Southside. We are big on coaching, education and the right people. We study and teach the mechanics of good movement, and focus on consistency and intensity. Our programming is based on the foundational principles of CrossFit, and peppered with technique and mobility work so that every level of member can not only participate but grow.

I’ve had the opportunity to travel the country teaching and lecturing at CrossFit Certifications as part of the HQ team. We have borrowed from dozens of quality facilities, programs and coaches. This gym is what we believe to be the very best parts of CrossFit. . . right here in Southside.
