CrossFit 405 South

Gym/Physical Fitness Center

CrossFit 405 South is a fitness facility designed to help any individual reach their health & fitness goals!


We are the original CrossFit facility in Norman Oklahoma in operation since 2007. CrossFit is many things. Primarily, it’s a fitness regimen developed by Coach Greg Glassman over several decades. He was the first person in history to define fitness in a meaningful, measurable way (increased work capacity across broad time and modal domains). CrossFit itself is defined as that which optimizes fitness by using constantly varied functional movements performed at relatively high intensity. CrossFit is also the community that spontaneously arises when people do these workouts together. In fact, the communal aspect of CrossFit is a key component of why it’s so effective.
