Wii Fit U has just been debuted at Nintendo's E3 conference.
It features a host of new mini games - we spotted trampolining, bobsleigh and something where you have to spray people covered in mode by lunging forward with the controller.
There's also a new Fit Meter that keeps track of how many calories you're burning.
You'll need to have a Wii Balance Board to play. No word on whether it's avWii U launch game.
