Yes, the wii can help you lose weight, but how much enjoyment can you get out of it? I’m beginning to think it’s for kids because of the cartoony avatars. Thank God for our kid who makes use of the wii with me. Now comes the PS3 move, the wii killer. I recently purchased sports champion, the wii equivalent of wii sports, and boy was I sweating after finishing just the bronze cup for gladiators! Even under airconditioning!
