Now some of those same people are lining up at the doctor's office.
What sets the Wii games apart is the motion sensitive controllers that require players to act out movements.
Players use the Wii remote to mimic the actions of swinging a racket, bat or club.
What they often forget is that it is not the real thing.
Kristyl Sunderman was on the golf team in college and does yoga every week, so she thought playing Wii golf and Wii yoga would not be a big deal.
She was wrong.
"After playing the Wii on two occasions my lower back is hurting, and my right knee," Kristyl said.
Dr. Ralph Gambardella says he is seeing people come in with injuries caused by playing Wii, and the potential for more is huge.
For example, he says that a Wii golf club is weighted differently than a real golf club, so that it is putting a strain in a different way.
"So what we have here is we have a combination of something that is in a way mind addictive, if you've ever played any of those things and you've got any competition in you. so that the time frame gets lost very quickly, and you think that you're doing it for 15 minutes and the next thing you know it's an hour later," Gambardella said.
After an examination, Dr. Gambardella found that Kristyl aggravated a degenerative disk condition in her back, and hurt her knee.
She will undergo physical therapy, and she has advice for other Wii players.
"Just be careful use caution, don't get overexcited," she said.
