Pretty much everything Kelly Starret puts on youtube and his blog, www.mobilitywod.com, is awesome. Every once in a while, his stuff is super awesome. His most recent video definitely falls under the 'super-awesome' category:
A lot of lifters and athletes have very lousy ankles from years of hard running, jumping, and just the basic demands of their given sport. A general rule I like to follow is if you can't squat well, then you probably can't run well. And you definitely have bad landing mechanics. And probably just aren't a good person in general. Just kidding... but not really. So fix your f-ed up ankles and become a better human.
