Taylor Swift’s ‘Shake it Off’ Plus This Epic 1989 Aerobic Dance Off Will Make Your Day [VIDEO]

This mashup gives 'Shake it Off' a brand new meaning! The original footage from this video came from the Crystal Light World Aerobics Championship back in the '80's, which was a) actually a real thing and b) apparently involved obscene amounts of spandex. In the OG version, the aerobics team dances to some synth pop, but the internet decided that wasn't good enough... and so, on this cold November day, this NATIONAL TREASURE was bestowed upon us.

Just watch and be amazed.
