I picked up a “Fuelband” (a bluetooth accelerometer, among other things) which syncs to all manner of digital apps, and the Nike Kinect Training thing, which is not in any way a game and actually feels very much like having a personal trainer. It will run a test on you, score you, and then create a schedule based on what you want to do. It’s the most sensible, functional, robust Kinect experience this side of Dance Central, the sort of thing that makes you say, “Oh. Right. Maybe I shouldn’t shove this magical camera deep, deep in the garbage.”
I can’t really make time for the gym right now; that’s not time I’m comfortable taking away from work or family. But I can make time for a workout I do in my living room, one that only counts good reps, one that keeps things sufficiently varied. My daughter will sometimes lie on my back when I’m trying to do a push-up; those are pretty hard. But this is something I can and will and have done.
