1. ROSA ACOSTA

Fitness video: Rosa Acosta! (2009)

It’s been nearly two years since we first watched the infamous Rosa Acosta stretching video, and our reaction is still the same: jaws on the floor and hands in our...actually, nevermind.

Seriously, this video is five minutes' worth of sweaty, stretchy, wood-creating flawlessness. It’s amazing—so much so, in fact, that we won’t even bitch about the DVD's $40 price tag. As for Acosta herself, we’re not sure what other talents she might have other than stretchy videos, but, trust, she has done enough already.
