Tuesday's unnerving visit to the set of Sweatin' Your 15 Minutes Away, with Heidi Montag was accompanied by an even more debilitating ebb of confidence in popular culture to ever make us smile again. So imagine the overwhelming (if perhaps coincidental) sense of joy that came along with revisiting Jane Fonda's early-'80s workout-video heyday — a brain-exploding, pre-ironic throwback to an era when only two-time Oscar winners were entitled to such garish Lycra supremacy. Sam Sparro's anthem "Black and Gold" provides the mid-tempo counterpoint, the entirety of which can be observed at Vimeo; our brains are full. Grateful, but full. And does she ever hit the spot.
