Just another Wii related injury

My ribs are KILLING me! I went over to a friend's house yesterday before we went out to see a movie. Well, he got a Wii for Christmas from his girlfriend. This is the first time I had the chance to play with a Wii, so I slipped on the wrist strap and tried Wii sports. I thought that boxing might be fun. It was fun, by the way, but what's NOT fun is the pain I'm in today. My ribs hurt like hell from the bobbing and weaving I was doing while fighting in this game. The game reacts to real movements you make, so I was bobbing around and punching and jabbing. Now, my ribs hurt because I wasn't used to that type of movement. I guess I'm just another Wii related injury to add to the websites, eh?
