Nintendo has announced that it will be giving Wii U owners the chance to fight the flab for free with a entirely gratis one-month trial of the forthcoming Wii Fit U.

From November 1st, North American and European Wii U owners will be able to download the game from the Wii U eShop and take part in 77 different activities — including 19 new training activities — many of which take advantage of the Wii U's GamePad.

If you want to keep playing beyond the month trial period, then you'll have to purchase a Fit Meter accessory — which will go on sale November 1st for $19.99 — and sync it to the game. The Fit Meter is a device you carry around with you which monitors your progress through the day and then reports back to the Wii Fit U software when you return home.

The download trial offer expires January 31st, and Wii Fit U will go on sale as a retail game and eShop download on Decemeber 13th. We've not heard if a similar offer will be made available in Europe, but we'll update this story if anything comes to light (UPDATE: the offer is confirmed for Europe, too — as you can see from the video below).

Here's what Nintendo President Reggie Fils-Aime had to say about the offer:

Wii Fit U is all about ‘fun fitness’ for everyone in the family. With this special offer, Nintendo is making it easier than ever for families to get active and stay active, making now the perfect time to upgrade to Wii U. This is another example of the kind of value and variety that only Nintendo can offer.
