Why is everyone harping on about Usain having a "killer physique" ?
To me, he's just a lean person with no more muscle mass than the average gym rat and as for that video of him "training" and then kissing his 13" arms, I'd say he's no better in the gym than your average gym rat, but obviously extremely gifted genetically to run fast, (I haven't seen any videos of him [on youtube] squatting big or doing *any* big weights in the gym that would imply he's "built it", which is why I say extremely genetically gifted). It's like asking a cheetah what makes it run so fast - what's its diet, what's its training, what suppliments does it take etc, ..it doesn't do any of that, it's a cheetah, its just genetically made to run fast.
Not hating, just trying to rationalize what I see...
