Sorry - something esle that has crossed my mind. On all these Wii games, although you can set up a customised work out to do nothing but step, jumping jacks and running, if you do one of the pre-set work outs you are only really going to have say three lots of one to two minutes of these kind of exercises in a half hour workout. The rest is going to be things like weights, squats, lunges, boxercise and activities like tennis, water skiing etc. You would have to have a pretty sensitive neighbour to really disturb them I think.
