Are you giving your child (or your spouse or yourself) a Wii for Christmas in hopes that they'll get more physical activity in their day? Though Wii has been touted as the "active" video game that gets gamers up and off the couch, it's no replacement for real sports, says a recent study.

Wii users burn about 60 more calories per hour than those playing a sedentary video game, but that's nothing compared to what they would burn if they were out playing real-life games. Video games have their place, say experts, but kids and teens (and grown-ups) need more exercise than they can get in front of a TV screen.

What do you think -- do you work up a sweat when using a Wii?
