Let's face it: most of us are going to pig out this Christmas before promising to lose a lot of weight. New Year's resolutions can be a pain, but the Wii U Fit Meter makes daily exercise a bit more fun and can be yours for just a tenner at Tesco Direct.
You'll need a copy of Wii Fit U in order to fully utilise this basic piece of wearable technology, which tracks your activity, calories burned and steps taken throughout the day. You can then sync this data wirelessly with your Wii U GamePad when you get home. Interestingly, it's also much the same as the PokeWalker (remember that thing?), only with more advanced software.
