CF 215 Information NOTE: While CrossFit 215 is not about reinventing the wheel, we do hope to breakdown and leap over the traditional model of fitness built on body-building mentalities, isolation movements, and extended aerobic sessions. CrossFit is about shedding the "big box" stigma of the traditional gym settings and turning back to the rugged and raw foundations of exercise. Most importantly, this means removing the machines from the gym floors and opening up space for movement and true fitness.
