#TBT: Kris and Bruce Jenner get physical in naff '90s workout vid

Warning: Your eyes may sting from all the spandex in this video.

Thanks to Khloe Kardashian's brilliant Vine up top, the whole world has been reminded of Kris and Bruce Jenner's naff workout vids from the '90s…which is a lycra-filled trip down memory lane for us at FIX HQ.

Coordinating in black, watch as the Olympic gold medallist instructs the reality TV momager on how to 'stand erect' on a treadmill. Erm, isn't that a given?

The short footage is from the former couple's first workout vid Power Walk Plus: Getting Started with Kris and Bruce Jenner, which is still available on VHS for $20. Yep, that's still a thing.

Sigh… we guess the couple that exercises together, doesn’t always stay together.
