For far too long I've heard people misrepresent CrossFit as a jocks-only club for crazy people that just throw around kettlebells, do muscle-ups, and half-assed versions of olympic lifting. I've had well-respected colleagues scoff at it as a patient(injury)-generating machine, and have had patients assume they'd never be able to do anything "as intense" as CrossFit.
Honestly...I even had some of these misconceptions myself.
