Before the world was Keeping Up with the Kardashians, it was working out with Bruce and Kris Jenner.
Kris' daughter Khloe Kardashian tweeted the humorous flashback Vine video, with the caption reading: "Who knew that Kris & Bruce Jenner had their very own tape? #PowerWalkPlus."
In the clip, Bruce is really selling the Power Walk Plus, saying, "You can pick it up, but you control the pace, as long as you stay nice and erect, you're gonna be OK."
The former reality star couple both seem to be in great shape as they sport matching all-black exercise outfits in the vintage video.
