Things don't get much better than hooking a Nintendo Wii and a Wii Fit up to an enormous flatscreen television in an empty meeting room, then inviting the entire office to come and have a go on Nintendo's new fitness-training game.

Following the Life & Style channel's week-long diary of a Wii Fit beginner, MSN collectively had a bash on the sensor mat, showing off our yoga techniques. Evidently, some of us have better natural balance than others.

I was pleasantly surprised by the accuracy and sensitivity of the combined Wii sensor bar and Wii Fit mat, and I definitely will mull over the prospect of adopting this game as a fitness regime rather than getting down to finally joining a new gym.

Actually, when I say things don't get much better than an office- wide Wii Fit trial, I mean to say that it could possibly be topped by a trip to the Rockstar London pad and getting a three hour demonstration (and hands-on) with Grand Theft Auto IV.

Which is what I did yesterday. These are exciting times, people. You can catch Tech & Gadgets' first impressions on GTA IV over here: A first look at GTA IV.
