How can I play Wii Sports Tennis to make it burn more calories/energy? Notes:
I realize that, even played differently, Wii Tennis doesn't qualify as exercise.
One way to burn more energy is to never serve, and always receive. That way, you don't get the "power serve" advantage where you "automatically" win the point w/ virtually no effort when the opponent can't return the serve.
Another way: I'm right-handed, and now play with my left hand, on the theory it requires more energy to co-ordinate my weaker hand (true?).
These methods help slightly, but are there others?
I considered taping the WiiMote to my arm and then swinging my arm to control the racket, but I'm guessing that won't be very playable.
I realize the Wii Fit qualifies as exercise, but find the games boring after a while.
Another game I'd like to "burn more energy" in is Wii Mario Kart.
