Forum Thread: Fitness game for my dad?

I recently purchased a new Xbox Kinect and love the way it performs. Now I am looking at buying a new fitness game for my Dad (He is 70 yrs old). I really have no ideas which one would be perfect for a 70 yrs old man. Can anyone recommend me the best one? I searched online for awhile, but found not much information on Kinect games, so I thought to ask other Kinect owners.

Thanks for your inputs.
