Case in point: the MX9 Workout Master by Motivatrix is a full-body workout machine in which sensors on a platform and in a ring above detect a user's movements and input them into a monitor. There are a variety of games, exercises and choices of music to choose from, and the display will keep track of the user's performance. Sound like a video game? Well, that's the point.
"Your body is a joystick...this is a way to take those Nintendo kids and give them a reason to get a sweat," Parrish Graumann, fitness director at Motivatrix, told the San Francisco Chronicle.
The MX9 was on display at last week's International Health, Racquet & Sportsclub Association convention in San Francisco.
