Gritty toughness meets manic, crazed fun. 80s-tinged Disco/Rock aerobic music that I find ultra-positive and empowering, regardless of the fact that when I wear spandex, I look like a balloon animal. Edgy electric guitars create a driving ostinato of pelvic thrusts, while a four-on-the-floor kick drum, vocal grunts/"whoo hoos" and hi-hats create propulsive squat-thrusting that @:12 explodes into a brass-accented flurry of enthusiasm, motivation and a confusing mix of metaphors. The cut starts again @:35, but this time the guitar-driven gruffness remains aggressive and rough-sounding longer, appropriate for sports bravado, overconfidence and image spots. The full, celebratory mix returns @1:28 with driving drums and extra Latin percussion.
