no my wife doesn't need a wii to learn to box, she learnt that from her dad , but it means she can get back in to shape
2 birds with one stone, the misses will be happy you bought her a wii fit, in a week or so she will give up and you'll have it all to yourself to play footy and she will not say anything to you, caz if she does, ask her to start using the wii fit again
