Happy to break the cycle that was going on :)

Are you a lazy bum? If so I agree.

Perhaps it appeals to gamers, casuals, and non-gamers.

I probably just blew your mind.

Sadly yes but I've just got back in the gym. Fast Food is a motherfucker. Glad you finally agreed with me also lol. 

I believe the focus of these apps is not just targeted at non gamers, its tageted at a late 20s on up who have a wife and family.  All of these apps seem to be a concerted way for MS to make purchasing a 500 device an easier sell for the game playing Dad.  When you have a family you start to look for value, especially when you are trying to sell something like this to the wife.  Do not be surprise if MS comes out with a E-learning app for the kids and probably some type of language app because it just makes sense to use Kinect in those ways.

So you're not a lazy bum, at least not any more, and hence you can't claim the fitness app has caused you to overcome the lazyness of your bum (or is it lazy bumness) as you are dealing with it already. I think you need to go back to your unhealthy ways for a few more months to give your Kinect Fitness evangelism more credibility.

Edit:

You started this BS by writing a post that had nothing to do with mine. Agree?

In what way is this workour routine personalised? With all due respect to the awesome products that these routines are, nothing here is personalised and since these are just gonna be the same movies you get on a DVD played with just a couple of nice gimmicks for motivation I see no justification for calling it a "personalised workout routine". The only thing could be watching your personal progress, but that doesn't turn this app into a personalised workout routine, neither does this require a monthly fee. Plus I already do that with a piece of paper :P

Kinect and Fitness is a natural fit. I've always said that Fitness and Dancing are the two things that Kinect is great for, because that's where Kinect is obviously superior to any other available input device.

But I don't quite understand what's special about this Xbox fitness app that would justify spending a periodical subscription fee? I mean, what does this app offer that the other Kinect fitness software (like "Your Shape", my personal favourite) just can't?

Now don't get me wrong, I actually see great potential for an online Kinect Fitness program. I've even thought about it myself a long time and thought it was a great idea. Because an online-supported fitness program could really offer significant motivational benefits over passive/dumb solutions like "workout DVDs" (which I consider to be much less unlikely to actually have positive effects than say, going to a gym).

It's definitely possible to make a great online-supported Kinect fitness app that would be so motivational that it would easily justify a certain periodic subscription fee. But I've seen nothing really interesting in the Kinect Fitness announcements so far.

What is the difference between me not being able to do an exercise because of a physical limitation or just not successfully doing it properly?

I'm not implying that a sophisticated algorithm can't be employed to help determine this or determine other exercises that may be possible instead, but more often than not people in an exercise routine do better with human to human feedback.  They stick to it longer and try harder.  Insulating someone entirely from the human interaction won't have the same effect.
