Comparing this to other console fitness products out there, Your Shape seems so much more intense and geared up to 'serious' fitness - I was really surprised at how intense some of the workouts were (especially the toning ones), so don't be tempted to dismiss this one as 'play' fitness - it's definitely a credible home fitness product.
It's quick and easy to get up and running with, and you can be doing workouts within minutes and tracking your progress. Working on the workouts themselves is not dissimilar to using a workout DVD - you watch and copy the actions on screen in time - with the difference that they're more tailored to your own needs, and you get constant feedback throughout. Brilliant!
Despite the serious edge and the demanding workouts, there are lots of fun activities as well - one of my favourites is the block-punching game, which quickly works up a good sweat at the higher levels. Together with the workouts, they make this a pretty comprehensive fitness tool for the XBox.
