I'm a martial artist, a lazy martial artist, I like fighting but I have very little motivation to do sit ups etc. I've not really paid much attention to the DS's releases when it hasn't been a big game that interests me, I've ignored most health/brain training games. I was wondering if the DS has a version of Wii Fit, something like it or something coming out in the future to help make training a bit more structured and interesting. It was that walking game that was just released that made me think about this.
