I love the wild flow in this Equinox video. This guy's dance-like movement reminds me of capoeira. My favorite parts are when he flips his downward dog effortlessly, and that insane vaulted leap off the log.
Talk about using your own body to tone in a way that's both manly and graceful!
PS For another kick-ass video by the same group, check out this one of Briohny Smyth.
