I love wii step and hula hoop,start off with those, 30 mins a day. Now I've bought wii fit plus really cheap £10 and there's lots more on it,especially unlock able games. I jog now 30 mins daily on my wii,I've unlocked all the cycling challenges too,it gives you a goal,determined to unlock stuff. I've clocked up 50 hours or more since Oct. I hated exercise,I love it telling me daily how many hours I've done. Free step and jogging is good for watching tv whilst doing it.
I've gone on to buy a reebok trampoline now to do Instead or as well.
