Mine is to do more exercise too, i used to do quite a bit when i was at Uni, however that kinda stopped once i graduated. All i do now is walk 10 mins for the bus, then walk 5 mins when i get off the bus at work. Then of course the same again going home.
I wouldn't say i'm out of shape, but i do spend all day sat in front of a computer at work, so it cant hurt to be more active.
