In the latest video showcasing Wii Fit U, Nintendo introduces the long-lost cousin on the Pokéwalker, the Fit Meter.

Using the Fit Meter, Wii Fit U players will be able track and monitor their athletic activity throughout the day, and then upload the data to their Wii Fit U progress.

The video shows players using their Fit Meter data to progress an avatar up tall, iconic landmarks like the pyramids or the Eiffel Tower.

Wii Fit U is available to download now on the eShop. It's available as a free game for a month, and if you sync a Fit Meter with your game, it will unlock the full game permanently. The game will be available at retail on December 13 and it will include a Fit Meter, but it will also be sold separately.

The last time we spent any real time with Wii Fit U was at E3 2012. You can check out our preview here.
