Usually, when we show you parkour, it's footage of successful, awe-inspiring runs. The point is to highlight finesse in movement. But actually getting to that skill level takes a lot of practice—and failed runs.

And boy, do those failed runs look painful judging from this compilation video by Uniformedia. I couldn't help but cringe at nearly all of these. It kind of makes me wonder what the casualties of awesome, injury-less parkour videos actually are—cause the 'fails' aren't the sort of thing we typically get to see!
