Who needs a working hip anyway?
There's a plethora of videos on YouTube showing the technical wizardry of athletes performing amazing stunts and tricks, which is fine, but what about the dedication that goes into those tricks? This b-side from Emerica's Stay Gold video shows the work that rider Heath Kirchart put into landing the perfect trick.
It's an almost painful video to watch, as Heath repeatedly throws his body down stairs and off a humongous mega-ramp in order to get the perfect part. Somebody get the man an ice pack and a cold beer!
