The sun is out and my mind has wandered to the bikini sitting in the drawer, challenging me to put it on and head down to the beach. After a winter of desk-sitting and potato-eating, I don't dare.

Thankfully, help is at hand with fine videogame apparati. In no time I shall be fit as a fiddle.

My six week fitness regime is inspired by two blokes who have used WiiSports to lose poundage. JR aimed to lose 80lbs (approx. 5.7 stone) and has just about done it in the six weeks he's been going, by changing his lifestyle habits and playing on his Nintendo console daily. hey_suburbia lost 9lbs (just over 1/2 a stone) by playing the Wii for 30 minutes extra per day. No lifestyle change, just Wii play.

So I'm going to mash up the two experiments, by cutting out snacking (I love snacking) but otherwise keeping my lifestyle the same. I'm also going to make things more interesting, by integrating two days of Sony's Nike EyeToy Kinetic workouts into my daily Wii-playing regimen. I aim to lose one stone - more than JR's loss - in six week's time. Can it be done? If PE classes are integrating dancing games into their lesson plans and research suggests the Wii has health benefits, why not?

You can follow the progress at Traineo, which actually offers a "Wii" category for type of exercise. Marvellous. Expect some hilarious vids on the gamesblog's YouTube channel, once I get the courage to show you.
