We blame our under indulgence in late night foreign infomercials, but still, how did we all miss the Jackie Chan J-Mat Fitness? Released back in 2005—two years before the world exploded over Wii Fit—the J-Mat featured four buttons that allowed users to follow along Chan's aerobics routine while software tracked fitness over time. It was fairly expensive, costing $90 and requiring a $80 XaviXPORT console to operate. And, of course, Nintendo didn't package it with the Wii global phenomenon.

Thanks to YouTube, we even have a clip of the product in action:

Oh, but before all the fanboys freak out, we just wanted to clarify that we realize Jackie Chan didn't really invent Wii Fit's Balance Board. That honor goes to Amiga.
