Nichole Harris is the Treadmill Dancing Queen, and she's found a way to make her workout fun.   She's a hometown girl and has been dancing on the treadmill for more than two years.  The video was recorded by Robert Gonzalez, who says the video has been watched more than a million times.   Nichole has already been on "Inside Edition", and plans to appear on "Ellen" and "The Today Show".    I know if I tried this at home I would end up breaking a limb or a lamp or something, but I'm sure I would have fun!
