Wii and Physical Therapy

[Tadao]

So... I'm thinking of getting a Wii for the main purpose of physical therapy.
What I need is to keep my neck, back and hips moving. I'm sure bowling is a good one for that, as would tennis.

Why am I asking you then? Well, I figured you guys who play all the games could clue me into some fun ones that would help as well. I might get into the bowling one, but I don't think I'd play tennis much. I've never played the Wii so I don't know what games I should get with it.
